Description

  The present invention relates to a technique for efficiently erasing dubbing source data after dubbing data in a video recording apparatus.

Currently, various video recording devices such as HDD recorders and next-generation DVD recorders are provided. In such a video recording apparatus, for example, a function of dubbing data recorded in the HDD of the video recording apparatus to another recording medium such as another HDD or next-generation DVD for the purpose of securing a recording capacity or backup. Is also provided. With regard to digital broadcast video data, recording data that has not reached the limit of dubbing due to so-called “dubbing 10” started in July 2008 is no longer subject to “move” processing. Therefore, even if the video data has been dubbed a plurality of times, the operation is changed so that the original video data remains in the recording medium without being erased as in the prior art. As described above, dubbing of data in the video recording apparatus can now be performed relatively freely. By the way, the original data that has been dubbed or the like is basically unnecessary, but there is also data that you want to keep on the contrary. For this reason, after the data dubbing process, the user must sequentially determine whether or not to erase each piece of data and take an erasure procedure. For this reason, for example, in Patent Document 1, attribute data such as a dubbed flag is added to the data dubbed in the video recording apparatus and managed. A technique is proposed in which dubbed data is listed as deletion candidates using the attribute data and proposed to the user.
JP 2004-297427 A

  However, even in the above conventional technique, after the data dubbing process, the user needs to select data to be deleted while viewing the deletion candidate list again. In other words, although the number of determination targets is narrowed down by the deletion candidate list, there is a possibility that unnecessary trouble may occur with respect to the data in the list such as, for example, fast-forwarding and viewing and reconfirming the contents. As described above, in the conventional technique, there is a problem that the user is forced to do unnecessary work when determining whether to delete dubbed data. In addition, in the so-called “dubbing reservation” in which the dubbing process is executed especially during the user's sleep by reserving the execution time, is the actual dubbing process performed after the user decides the dubbing, and then deleted? Time will elapse until a decision is made. For this reason, with regard to data erasure after the dubbing reservation, there is a high possibility that the user will have to troublesomely review and judge the data contents again.

  In order to solve the above problems, the present invention has a dubbing reservation function for performing dubbing of data by reservation, and further, a GUI (graphical) for selecting whether to delete original data after dubbing by reservation. (User interface) A video recording apparatus having a function of causing a user to select data erasure in advance by outputting a screen during a dubbing reservation operation is provided.

  Specifically, a first recording unit having a first recording medium, a second recording unit having a second recording medium, a control unit for controlling the recording unit, a user interface unit, and an operation result on the user interface unit And a holding unit for holding the video recording apparatus. Further, the user interface unit outputs a screen for allowing the user to input whether to make a reservation for control to record the data of one recording medium on the other recording medium, and the first GUI means includes the user When receiving the input, a screen is output that allows the user to select whether to control whether or not to delete the data recorded on the one recording medium according to execution of the reservation. And a second GUI means. Such a video recording apparatus allows the user to select the dubbing reservation and delete the dubbing source data without taking the time, thus causing unnecessary trouble such as confirming the data contents again in detail. You do n’t have to.

  The present invention also provides a video recording apparatus having a function of automatically erasing dubbed original data after a predetermined time has elapsed when data is dubbed. Specifically, a first recording unit having a first recording medium, a second recording unit having a second recording medium, a control unit for controlling the recording unit, a user interface unit, and an operation result on the user interface unit And a holding unit for holding the video recording apparatus. Further, when the control unit has dubbing control of data by the control unit, the elapsed time measuring means for measuring the elapsed time after the dubbing, and the elapsed time measured by the elapsed time measuring means are a predetermined time. And a post-elapse erasing unit for controlling the recording unit so that the dubbing source data is erased. With such a video recording apparatus, the user can erase the dubbed data that has been dubbed once without any unnecessary effort by the user.

  The present invention also provides a video recording apparatus having a function of counting the number of times data has been dubbed and automatically erasing the original data after dubbing a certain number of times. Specifically, a first recording unit having a first recording medium, a second recording unit having a second recording medium, a control unit for controlling the recording unit, a user interface unit, and an operation result on the user interface unit And a holding unit for holding the video recording apparatus. Further, when the control unit has dubbing control of data, the control unit counts the number of times the data is dubbed, and a predetermined number for controlling the recording unit to erase the dubbing source data The erasing scheduled dubbing number holding means for holding the erasing scheduled dubbing number, which is the number of times of dubbing of the recording, and recording so as to erase the dubbing source data when the number counted by the number counting means reaches the erasing planned dubbing number A number erasing unit for controlling the copy unit. With such a video recording apparatus, the user can erase the data that has been dubbed a predetermined number of times and has been sufficiently backed up without unnecessary effort.

  In addition, in the video recording apparatus having the above function and configuration, a video recording apparatus is also provided in which the user can arbitrarily change the number of scheduled deletions for dubbing, which is a criterion for whether or not to delete. Specifically, the user interface unit of the video recording apparatus having the above-described configuration further includes third GUI means for outputting a user interface screen for changing the scheduled deletion dubbing count held in the scheduled deletion dubbing count holding means. It is characterized by that.

  In addition, even when data is dubbed, for example, video data with HD (high definition) image quality is reduced to SD (standard) image quality and recorded on a DVD. For example, data may not be dubbed as it is. Therefore, in the case of dubbing accompanied by a reduction in the amount of information that degrades the video quality of the original data, the video is configured such that the data is left with a low priority for automatic deletion of the original data. A recording device is also provided. Specifically, a first recording unit having a first recording medium, a second recording unit having a second recording medium, a control unit for controlling the recording unit, a user interface unit, and an operation result on the user interface unit And a holding unit for holding the video recording apparatus. The user interface unit further includes fourth GUI means for outputting a screen for allowing the user to input recording conditions when performing control for recording data of one recording medium onto the other recording medium.

And an overwriting control means for overwriting the data on which the dubbing control of the data has been controlled by the unit. With such a video recording apparatus, dubbed data can be efficiently erased without the user's trouble with respect to data that is repeatedly recorded such as a continuous television drama.

  According to the present invention configured as described above, the user can easily erase the data that has been backed up by dubbing or the like without unnecessary effort. In addition, if the dubbing is a recording format that involves deterioration of video quality, the data can be preferentially left.

  The “control unit” (0203) has a function of controlling the recording unit, and can be realized by a CPU, a main memory, a control program, or the like, for example. Specifically, in the control unit, for example, video data received by the tuner on the first recording medium or the second recording medium or input from an external device in response to a recording operation command input by an input device such as a remote controller or an operation panel. To control the recorded video data. In addition, the video data recorded on the first recording medium or the second recording medium is read in accordance with a reproduction operation command input by the input device, and control is performed for reproduction to the decoder. Of course, the control of the control unit may be executed according to instructions automatically generated by, for example, a task scheduler or other programs, as well as control according to various operation instructions input by the input device.

  Further, the control unit performs dubbing control for recording the video data recorded on the first recording medium on the second recording medium (or conversely recording the video data from the second recording medium to the first recording medium). It has a function. The video recording apparatus according to the present embodiment further displays a GUI screen for designating whether or not to delete the dubbing source data with the following configuration when performing an operation input for performing the dubbing control in the controller by reservation. It is characterized by that.

  The “user interface unit” (0204) has a function for receiving an operation input from a user, and includes, for example, an input device such as a remote control device (transmitter and light receiver) and operation buttons, and a user interface program including various GUIs. Etc. can be realized. The user interface unit outputs two types of linked GUI screens as will be described later.

  The “holding unit” (0205) has a function of holding an operation result for the user interface unit, and can be realized by, for example, an HDD, a non-volatile memory, or another recording medium. “Operation result” refers to information related to an operation accepted by the user interface unit. Specifically, for example, an operation result corresponding to an operation command received by an input device of the user interface unit is recorded on the various recording media. It is a state of doing. The operation results to be recorded include, for example, identification information indicating an input operation command, processing contents actually controlled by the control unit according to the operation, and identifications indicating calculation results and processing results of the processing Information. Further, the operation reception time, the control execution time according to the operation, or the control execution time according to the reservation if the operation is a reservation operation may be held as the operation result.

  In this embodiment, the “dubbing reservation operation result” and “deletion / non-erasure of video data to be reserved dubbed” input via the following GUI are held in this holding unit.

  The “first GUI means” (0206) has a function of outputting a screen for allowing the user to input whether to make a reservation for control of recording data of one recording medium onto the other recording medium. For example, the first GUI program Etc. As a specific screen example, for example, a display screen as shown in FIG. In this screen example, for example, a dubbing mode selection input is performed by a user operation. At this time, for example, when dubbing reservation 1 is selected, the screen is changed to an instruction input screen for dubbing data and a dubbing reservation execution time input screen, and an operation input related to dubbing reservation is accepted.

  Whether the “second GUI means” (0207) controls to erase the data recorded on the one recording medium in response to execution of the reservation when the first GUI means accepts the user's input , Has a function of outputting a screen for allowing the user to select whether to control to not erase, and can be realized by, for example, a second GUI program. As a specific screen example, for example, a display screen as shown in FIG. This screen is displayed on the display after the input screen transition for the dubbing reservation, and accepts a selection operation as to whether or not to delete the dubbing source data after the dubbing is executed. The input screen by the first GUI unit and the input screen by the second GUI unit may be displayed as separate pages as shown in FIG. Alternatively, as shown in FIG. 3, a screen for receiving a dubbing reservation selecting operation and a dubbing source data selecting operation for deleting the dubbing source data may be displayed together in one page.

As shown in this figure, for example, an operation of performing dubbing processing on the second recording medium at 02:00 on August 9, 2008 regarding the video data recorded on the first recording medium identified by the ID “2007 — 1228 — 1902 — 08ch” The result is retained. Further, after the dubbing process is executed, an operation result indicating that the dubbing source video data erasing process is executed is held. Then, for example, a task scheduler is generated according to the operation result held in the holding unit, and video data dubbing control of the first recording unit and the second recording unit by the control unit is reserved and executed at a specified time. Then, after executing the dubbing control, the control unit can further control the recording unit of one of the recording media on which the dubbing source data is recorded to erase the video data.

  As described above, the video recording apparatus according to the present embodiment enables the user to select dubbing reservation and delete data of the dubbing source without taking time. In other words, after the dubbing by reservation has been executed, there is no need to generate unnecessary trouble such as forgetting the details of the data contents and checking again because the time has passed.

<Hardware configuration>
FIG. 5 is a schematic diagram showing an example of the configuration of the video recording apparatus when the above functional components are realized as hardware. The operation of each hardware component in the dubbing reservation and the subsequent video data erasing process will be described with reference to FIG. As shown in this figure, the video recording apparatus is a control unit, and includes a “CPU (central processing unit)” (0501) for executing various other arithmetic processes, and a “main memory” (0502). ing. In addition, a “first recording circuit” (0503) that is a first recording unit and an HDD, a “second recording circuit” (0504) that is a second recording unit, a next-generation DVD, a drive thereof, and the like are also provided. Of course, the second recording medium may be the same HDD as the first recording medium, and the types of both recording media are not limited. In addition, the “flash memory” (0505) as a holding unit, the “VRAM” (0506) and “display” (0507) as a user interface unit, and a “photoreceptor” that receives an operation signal from a remote control ( 0508). They are connected to each other via a data communication path such as a “system bus” to transmit / receive information and process information. A program is read out to the “main memory”, and the “CPU” refers to the read out program and executes various arithmetic processes according to the procedure indicated by the program. In addition, a plurality of addresses are assigned to each of the “main memory”, “HDD”, “next generation DVD”, and “flash memory”, and the addresses are specified and stored in the arithmetic processing of the “CPU”. By accessing the data, it is possible to perform arithmetic processing using the data.

  Here, the video recording apparatus according to the present embodiment records video data acquired by a “broadcast reception tuner” or an “external video input circuit” (not shown) in the “HDD”. Thereafter, an operation signal from the remote controller is received by the “light receiver”. When the received operation signal is demodulated, the “CPU” interprets the user interface program, and reads data for displaying the first GUI screen on the display in accordance with the user interface program, to the address 1 of the “main memory”. Then, the first GUI screen is drawn on the “VRAM”, and the screen as shown in FIG. 1A is displayed on the “display”. The user operates the remote controller while viewing the first GUI screen displayed on the display. Then, when the user inputs an operation for dubbing reservation, the video recording apparatus according to the present embodiment displays data for dubbing reservation, for example, identification information of video data to be dubbed, execution time of dubbing reservation, and the like. The operation signal shown in FIG. When the dubbing reservation data indicated by the received operation signal is stored at address 2 of the “main memory”, the “CPU” interprets the user interface program and displays the second GUI screen accordingly. Data to be read is read out at address 3 of the “main memory”. Then, the second GUI screen is drawn on the “VRAM”, and the screen as shown in FIG. 1B is displayed on the “display”. (Of course, as shown in FIG. 3, the first GUI screen and the second GUI screen may be displayed together in one screen.)

  Subsequently, while viewing the second GUI screen displayed on the display, the user performs a selection input operation for determining whether or not to erase the dubbing source data after executing the dubbing reservation. Then, the video recording apparatus accepts the operation result at the “light receiving unit” and stores it at address 4 of the “main memory”. Then, data relating to the dubbing reservation is written in the “flash memory” in association with information indicating the presence or absence of the erasure reservation operation. Thereafter, referring to time information from an unillustrated built-in clock or the like, when the reserved time comes, the “CPU” interprets the control program, and reads out the video data designated as the dubbing source from the “HDD” accordingly. Then, the “second recording circuit” is controlled, and the read video data is written to another recording medium such as “next generation DVD”. In addition, if an erasure reservation “present” flag is associated with this dubbing reservation process, the “CPU” controls the “first recording circuit” according to the control program, and the dubbing source recorded in the “HDD” is recorded. For example, the video data is deleted immediately after the dubbing process is completed.

<Process flow>
FIG. 6 is a flowchart illustrating an example of a processing flow in the video recording apparatus according to the present exemplary embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care. As shown in this figure, first, the first GUI screen is output to the display in accordance with, for example, an operation input from the user (step S0601). Then, in accordance with the first GUI screen output and displayed on the display, when the dubbing reservation operation result input by the user using an input device such as a remote control is received (step S0602), the second GUI screen is displayed on the display (step S0602). Step S0603). Note that the first GUI screen and the second GUI screen may be configured to be simultaneously displayed in step S0601 so as to fit within one screen as shown in FIG. Then, according to the second GUI screen, when an operation result indicating the presence / absence of erasure reservation input by the user with the remote controller or the like is received (step S0604), the operation result is recorded for holding in a holding unit such as a flash memory (step S0605). .

  Thereafter, referring to the built-in clock or the like, when a determination result indicating that the current time has reached the reservation time specified in the dubbing reservation is output (step S0606), one of them is determined according to the dubbing reservation held in the holding unit. The video data of the other recording medium is recorded on the other recording medium (step S0607). Subsequently, it is determined whether or not the operation result indicating “reservation erased” is held in the holding unit with respect to the dubbing reservation (step S0608), and if held, the data of one recording medium as a dubbing source is deleted. (Step S0609).

<Brief description of effect>
As described above, the video recording apparatus according to the present embodiment enables the user to select dubbing reservation and delete data of the dubbing source without taking time. In other words, after the dubbing by reservation has been executed, there is no need to generate unnecessary trouble such as forgetting the details of the data contents and checking again because the time has passed.

<< Example 2 >>
<Overview>
This embodiment also has two recording media as in the first embodiment, and has a function of automatically erasing the dubbing source video data when data is dubbed from one to the other recording medium. It is a recording device. The difference from the first embodiment is that the elapsed time after video data is dubbed is measured, and the dubbing source data is erased when a predetermined time has elapsed. As described above, the video recording apparatus according to the present embodiment enables the user to automatically delete data that has been dubbed once and has been backed up or the like according to the elapsed time without unnecessary effort.

<Functional configuration>
FIG. 7 is a diagram illustrating an example of functional blocks in the video recording apparatus according to the present embodiment. As shown in this figure, the “video recording apparatus” (0700) of the present embodiment is similar to the first embodiment in that “first recording section” (0701), “second recording section” (0702), “ It has a “control section” (0703), a “user interface section” (0704), and a “holding section” (0705). Since these constituent elements are the same as those described in the first embodiment, description thereof is omitted. Further, in combination with the first embodiment, a “first GUI unit” or a “second GUI unit” (not shown) may be provided. In this embodiment, the control unit of the video recording apparatus further includes an “elapsed time measuring unit” (0706) and an “erasing unit after lapse” (0707).

  The “elapsed time measuring means” (0706) has a function of measuring the elapsed time after dubbing when the control unit performs dubbing control of data. For example, the “elapsed time measuring means” (0706) This can be realized by a clock information receiver, an elapsed time measurement program, or the like. Specifically, when a dubbing operation from the user (including a dubbing reservation operation in addition to an immediate execution dubbing operation) is accepted by the function of the user interface unit, video data dubbing control designated by the operation is executed ( In the case of dubbing reservation, dubbing control is executed when the current time reaches the reservation time). When the dubbing process by the dubbing control is completed, the elapsed time is counted using the clock information received from the built-in clock or the external clock with the time as the count start time. Note that the timing of counting the elapsed time may be any timing as long as it is related to dubbing control, as well as the video data dubbing completion time. For example, in the case of dubbing reservation, it may be configured to start counting elapsed time from the time when the reservation operation is accepted (in this case, of course, the time when video data is deleted comes after the execution time of dubbing reservation). Configured).

  In this embodiment, the “user interface unit” is configured to output a screen that allows the user to select whether to control the original video data dubbed over time or not to delete it. You may do it. In this case, for example, on the input screen for the dubbing operation, the operation result indicating whether or not the erasing is performed is received and held in the holding unit. Alternatively, an operation result indicating protection from data erasure on the video data management screen or the like is held in the reception holding unit. Then, the operation result is managed in association with the identification information of the video data as shown in FIG. 8, and the elapsed time is counted for the video data associated with the “no erasure” or “protection flag present” data. It is good also as a structure of not performing.

  The “erasing unit after lapse” (0707) has a function of controlling the recording unit so as to erase the dubbing source data when the elapsed time measured by the elapsed time measuring unit reaches a predetermined time. For example, it can be realized by a CPU, a main memory, an erasing program after progress, or the like. Specifically, for example, the elapsed time measured by the elapsed time measuring means in a cycle such as 1 minute is compared with a predetermined time, and whether the elapsed time has reached or exceeded the predetermined time is determined by the CPU logic. Judgment is made by arithmetic processing. Then, when the determination result that it has been reached (exceeded) is output, the recording unit in which the dubbing source data is recorded is controlled to delete the video data. The predetermined time may be determined in advance and held in a flash memory or the like. The user interface unit may be configured to output a screen for accepting the change operation for the predetermined time.

  As described above, the video recording apparatus according to the present embodiment enables the user to automatically delete the data that has been dubbed once and completed the backup or the like according to the elapsed time without taking time and effort.

<Hardware configuration>
FIG. 9 is a schematic diagram illustrating an example of a configuration of the video recording apparatus when the functional components described above are realized as hardware. The operation of each hardware component in the dubbing source data erasing process over time will be described with reference to FIG. As shown in this figure, in the same way as in the first embodiment, the video recording apparatus includes a “CPU” (0901), a “main memory” (0902), a “first recording circuit” (0903), an HDD, Recording circuit "(0904), a next-generation DVD and its drive, and the like. In addition, a “flash memory” (0905), a “VRAM” (0906), a “display” (0907), and a “light receiver” (0908) for receiving an operation signal from a remote controller are also provided.

  Here, the video recording apparatus of this embodiment records video data received by a “broadcast reception tuner” or the like in, for example, an HDD. Thereafter, when an operation signal from the remote controller is received by the “light receiver”, GUI screen data for accepting a dubbing operation, for example, a recording list, etc. is read to address 1 of the “main memory” accordingly. Then, the GUI screen is displayed on the “display” via the “VRAM”. Then, the result of the dubbing operation received via the displayed GUI screen, for example, the designation of dubbing source data and the execution command for starting dubbing are stored at address 2 of the “main memory”.

  Then, the “CPU” interprets the control program and reads the video data designated as the dubbing source from the “HDD” accordingly. Then, the “second recording circuit” is controlled, and the read video data is written to another recording medium such as “next generation DVD”. Further, according to the elapsed time measurement program included in the control program, the “CPU” acquires the execution time of the dubbing process from an internal clock (not shown) and stores it in the address 3 of the “main memory”. Subsequently, the “CPU” reads a predetermined time held in the flash memory or the like to the address 4 of the “main memory” according to the erasing program after the elapse. Thereafter, the elapsed time is calculated by the arithmetic processing of the “CPU” from the current time acquired from the internal clock in a predetermined cycle such as 1 minute and the dubbing time stored in the address 3 of the “main memory”. Then, a size comparison process between the calculated elapsed time and a predetermined time stored in the address 4 of the “main memory” is executed by a logical operation process of the “CPU”. As a result of the comparison determination process, when the determination result that the elapsed time has reached or exceeded the predetermined time is output, the “CPU” deletes the dubbing source video data from the HDD according to the deletion program after the elapse of time. The process of performing the process is performed.

<Process flow>

The operation result is recorded for holding in a holding unit such as a flash memory (step S1003). Then, dubbing processing for recording the video data recorded on one recording medium on the other recording medium is executed according to the accepted operation result (step S1004).

  Further, the execution time when the dubbing process is executed is acquired, and the elapsed time from the execution of the dubbing is measured together with the current time acquired from the built-in clock (step S1005). Then, for example, it is determined in a predetermined cycle whether or not the measured elapsed time has passed a predetermined time (step S1006), and if a determination result indicating that the predetermined time has elapsed is output, one of the dubbing sources The data on the recording medium is erased (step S1007).

Since these constituent elements are the same as those described in the first embodiment, description thereof is omitted. Further, in combination with the above embodiment, a “first GUI unit” or “second GUI unit” (not shown), “elapsed time measuring unit”, “erasing unit after lapse”, or the like may be provided. In this embodiment, the control unit of the video recording apparatus further includes a “number counting unit” (1106), a “scheduled dubbing number holding unit” (1107), and a “number erasing unit” (1108). It is characterized by that.

  The “counting means” (1106) has a function of counting the number of times data is dubbed when the control unit performs data dubbing control, and is realized by a CPU, a main memory, a flash memory, a number counting program, and the like. can do. Then, the number of times of dubbing counted in each dubbing control is managed in association with the identification information of the video data as shown in FIG. 12, for example, and stored in a flash memory or the like.

  “Erase scheduled dubbing count holding means” (1107) has a function of holding the scheduled erase dubbing count, and can be realized by, for example, a flash memory or other various recording media. Further, “scheduled dubbing count” means a predetermined dubbing count for controlling the recording unit so as to erase the dubbing source data. For example, as will be described later in Embodiment 4, the count can be changed by the user. You may comprise.

  “Number-of-times erasing means” (1108) has a function of controlling the recording unit so as to erase the dubbing source data when the number of times counted by the number-of-times counting means becomes the number of times of scheduled dubbing, It can be realized by a CPU, a main memory, a number erasing program, or the like. Specifically, every time dubbing control is executed, the counted number of times of dubbing is compared with the number of times of scheduled dubbing, and it is determined by CPU logic operation processing whether the number of times of counting reaches the number of times of scheduled dubbing. . Then, when the determination result that it has been reached is output, the recording unit in which the dubbing source data is recorded is controlled to delete the video data.

  As described above, the video recording apparatus according to the present embodiment enables the user to automatically delete data that has been dubbed a predetermined number of times and has been backed up without any trouble. Similarly to the deletion of the dubbing source video data by the elapsed time described above, for example, the user interface unit accepts the presence / absence of protection of the video data. It may be configured not to count and not to be erased.

<Hardware configuration>
FIG. 13 is a schematic diagram illustrating an example of the configuration of the video recording apparatus when the functional components described above are realized as hardware. The operation of each hardware component in the erasing process of the dubbing source data according to the number of times of dubbing will be described with reference to this figure. As shown in this figure, the video recording apparatus includes a “CPU” (1301), a “main memory” (1302), a “first recording circuit” (1303), an HDD, A second recording circuit "(1304), a next-generation DVD and its drive, and the like.

  Here, as in the second embodiment, the video recording apparatus of the present embodiment records the video data received by the “broadcast reception tuner” or the like in the HDD, for example. Thereafter, when an operation signal from the remote controller is received by the “light receiver”, GUI screen data for accepting a dubbing operation, for example, a recording list, etc. is read to address 1 of the “main memory” accordingly. Then, the GUI screen for accepting the dubbing operation is displayed on the “display” via the “VRAM”. Then, the result of the dubbing operation received via the displayed GUI screen, for example, the designation of dubbing source data and the execution command for starting dubbing are stored at address 2 of the “main memory”.

  Then, the “CPU” interprets the control program and reads the video data designated as the dubbing source from the “HDD” accordingly. Then, the “second recording circuit” is controlled, and the read video data is written to another recording medium such as “next generation DVD”. In this embodiment, the “CPU” increments the numerical value of the number of times of dubbing execution of the video data held in the flash memory or the like according to the frequency count program included in the control program, and assigns it to the address 3 of the “main memory”. Store. Subsequently, the “CPU” reads the number of scheduled deletions dubbing held in the flash memory or the like to the address 4 of the “main memory” in accordance with the number erasing program. Then, the process of determining whether or not the number of times of dubbing stored in the “main memory” matches the number of times of scheduled dubbing is executed by a logical operation process of “CPU”. As a result, when a determination result indicating that the two match is output, the “CPU” performs a process of erasing the dubbing source video data from the HDD according to the number of times erasure program.

<Process flow>
FIG. 14 is a flowchart illustrating an example of a process flow in the video recording apparatus according to the present exemplary embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care. As shown in this figure, first, for example, a GUI screen for accepting a dubbing operation, such as a recording list, is output to the display (step S1401). Then, via a GUI screen output and displayed on the display, a dubbing operation result input by the user with an input device such as a remote controller, for example, dubbing source data designation information or a dubbing execution command is received (step S1402). The operation result is recorded for holding in a holding unit such as a flash memory (step S1403). Then, dubbing processing for recording the video data recorded on one recording medium on the other recording medium in accordance with the accepted operation result is executed (step S1404).

  Further, in accordance with the execution of the dubbing process, for example, the video data held in the flash memory or the like is incremented by 1 to obtain a new dubbing number N (step S1405). Then, it is determined whether or not the +1 incremented dubbing count N coincides with (exceeds) the preliminarily held erasure dubbing count α (step S1406), and if a judgment result indicating coincidence (exceeds) is output. Then, the data on one recording medium which is the dubbing source is erased (step S1407).

<Functional configuration>
FIG. 15 is a diagram illustrating an example of functional blocks in the video recording apparatus according to the present embodiment. As shown in this figure, the “video recording apparatus” (1500) of the present embodiment is based on the third embodiment and includes a “first recording section” (1501), a “second recording section” (1502), “Control Unit” (1503), “User Interface Unit” (1504), “Holding Unit” (1505), “Number Count Unit” (1506), “Erase Schedule Dubbing Number Holding Unit” (1507) , “Number-of-times erasing means” (1508).

Example 5
<Overview>
FIG. 17 is a diagram illustrating an example of a GUI screen related to the video recording apparatus according to the present embodiment. As shown in FIG. 17A, for example, an operation for dubbing high-definition video data such as digital broadcast recorded on the HDD onto the DVD is accepted. However, since the high-definition video data has a large data size, it cannot be dubbed to a DVD as it is. Therefore, as shown in FIG. 17B, the resolution is reduced to 640 × 480 SD (standard) image quality, the bit rate is reduced to MV64 (for example, 6 Mbps), and the data size of the video data is set. Is adjusted to be within the recorded data size of the DVD. Thus, when dubbing video data, there may be cases where the amount of information is reduced and the video quality is lowered for dubbing. Therefore, in the case of dubbing accompanied by such a reduction in the amount of information, the video recording apparatus according to the present embodiment sets the priority for erasing the dubbing source data on the assumption that complete backup with video quality is not possible. It is characterized by performing processing such as lowering.

    <Functional structure> FIG. 18: is a figure showing an example of the functional block in the video recording device of a present Example. As shown in this figure, the “video recording apparatus” (1800) of this example is similar to the first example in that “first recording unit” (1801), “second recording unit” (1802), “ It has a “control section” (1803), a “user interface section” (1804), and a “holding section” (1805). Since these constituent elements are the same as those described in the first embodiment, description thereof is omitted. In addition, in combination with the other embodiments described above, the configuration requirements such as “first GUI means” described in each embodiment may be further provided. In this embodiment, the user interface unit of the video recording apparatus further includes “fourth GUI unit” (1806), the control unit includes “information amount determination unit” (1807), “erase priority information generation unit”. ”(1808).

  The “fourth GUI means” (1806) has a function of outputting a screen for allowing the user to input recording conditions when performing control to record data of one recording medium onto the other recording medium. It can be realized by a program. As a specific screen example, for example, a display screen as shown in FIG. This screen example is configured to input conditions such as “resolution”, “bit rate”, “frame rate”, and “compression format” as recording conditions. Other recording conditions include, for example, conditions such as the appearance frequency of I frames (frames encoded without using inter-frame prediction), quantization coefficients, and the like. In the video recording apparatus according to the present embodiment, for example, under the conditions specified here when performing dubbing control, for example, the resolution, bit rate, and frame rate are lowered, or the compression format is changed to a compression format different from the original data. It is possible to perform dubbing after converting data and reducing the amount of information.

  The “information amount judging means” (1807) has a function for judging whether or not the recording based on the recording condition inputted using the fourth GUI means is a recording that reduces the information amount of the data with respect to the original data. For example, it can be realized by a CPU, a main memory, an information amount determination program, and the like. Specifically, for example, information such as “resolution”, “bit rate”, and “frame rate” in the original video data is acquired from the meta tag of the video data and compared with the recording condition received by the fourth GUI unit. . Then, when it is determined by the “CPU” size comparison determination that the reduction rate of any of the numerical values is lower than a predetermined rate, it is determined that the amount of data information has decreased. In addition, the information amount determination processing may be performed before dubbing by comparing various conditions before and after dubbing as described above, or the amount of video data actually dubbed under the above recording conditions may be calculated. It may be determined whether or not the data amount has decreased by acquiring and comparing it with the data amount of the dubbing source.

  As described above, in this embodiment, the reduction in the amount of information is determined in order to determine whether or not video data can be backed up while maintaining the video quality. However, when the compression format is changed to one with high compression efficiency (for example, when the video data in the Mpeg2 compression format is changed to video data in the H.264 / AVC compression format), the bit rate is greatly reduced and the amount of information is reduced. It is said that the video quality will hardly change even if it is reduced. Therefore, if the compression format change due to the recording condition is a change to a format that increases the compression efficiency as described above, the amount of data information has decreased even if the bit rate etc. is significantly lower than the original one. You may comprise so that it may not judge.

  The “erase priority information generation means” (1808) has a function of determining the priority of erasure of the original data after recording is performed according to the recording condition according to the determination result by the information amount determination means. Or a main memory, an erase priority information generation program, or the like. Specifically, if the result of the determination is that dubbing has been executed under a recording condition that reduces the amount of information, it can be assumed that dubbing has been performed in a state where the video quality has deteriorated as described above. Therefore, it is assumed that erasure priority information having a low priority is generated for the dubbing source video data, assuming that the video data is not completely backed up. Further, as a method for calculating the erasure priority information, for example, a method of calculating by substituting a numerical value such as the above-mentioned bit rate decrease width into a predetermined function can be cited.

  Note that the priority of erasure determined here may be used, for example, in the order in which the erasure candidate list is presented to the user. Or you may comprise so that predetermined time may be determined according to a priority, for example in combination with the video recording device of the said Example 2. FIG. In this way, in the case of video data having a low erasure priority, it can be erased after a longer time than otherwise. Alternatively, in combination with the third embodiment, for example, the number of scheduled deletions may be determined according to the priority. As such, video data with a low erasure priority can be dubbed more times than otherwise.

  As described above, in the case of dubbing accompanied by a reduction in the amount of information by the video recording apparatus of the present embodiment, it is assumed that complete backup with video quality has not been performed and the priority order of erasing the dubbing source data is set. Can be lowered.

<Hardware configuration>
FIG. 19 is a schematic diagram illustrating an example of the configuration of the video recording apparatus when the above functional components are realized as hardware. The operation of each hardware component in the generation process of erasure priority information corresponding to dubbing with different recording conditions will be described with reference to FIG. As shown in this figure, the video recording apparatus includes a “CPU” (1901), a “main memory” (1902), a “first recording circuit” (1903), an HDD, 2 recording circuit "(1904), next-generation DVD and its drive, etc. In addition, a “flash memory” (1905), a “VRAM” (1906), a “display” (1907), and a “light receiver” (1908) for receiving an operation signal from a remote controller are also provided.

  Here, the video recording apparatus of this embodiment records video data received by a “broadcast reception tuner” or the like in, for example, an HDD. Thereafter, when the operation signal from the remote controller is received by the “light receiver”, the fourth GUI screen data for receiving the dubbing recording condition is read to the address 1 of the “main memory” accordingly. Then, the fourth GUI screen is displayed on the “display” via the “VRAM”. Then, the dubbing recording conditions received via the displayed GUI screen as shown in FIG. 17, for example, the resolution and bit rate designation conditions, and the dubbing execution command are stored at address 2 of the “main memory”.

  Then, the “CPU” interprets the control program and reads the video data designated as the dubbing source from the “HDD” accordingly. Then, the “second recording circuit” is controlled, and the read video data is written to another recording medium such as “next generation DVD” under designated recording conditions. Further, the “CPU” acquires the resolution and bit rate information from the meta tag data of the original video data according to the information amount determination program included in the control program. Then, a reduction rate indicating how much the resolution and bit rate indicated by the recording conditions are reduced from the original resolution and bit rate is calculated by the calculation processing of the “CPU”, and the information amount determination result is “main memory” "Is stored at address 3. Subsequently, the “CPU” reads a predetermined function stored in the flash memory or the like according to the erasure priority information generation program, and substitutes the numerical value of the above-described decrease rate into the function. Then, a function in which the reduction ratio is substituted by the calculation process of “CPU” is calculated, and the calculation result is stored in address 4 of “main memory” as erasure priority information. Of course, the calculation of the erasure priority information is not limited to the processing using the reduction ratio or function as described above, and may be various, for example, using a table that associates the reduction ratio with the priority value. Then, for example, the order of arrangement of the erasure candidate list is determined using the calculated erasure priority information, and is used for the predetermined time and the erasure scheduled dubbing number determination process in the video recording apparatus of the second and third embodiments. It is a state of doing.

<Process flow>
FIG. 20 is a flowchart illustrating an example of a processing flow in the video recording apparatus according to the present embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care. As shown in this figure, first, for example, a fourth GUI screen for receiving recording conditions for dubbing as shown in FIG. 17 is output to the display (step S2001). Then, via the fourth GUI screen output and displayed on the display, a recording condition input by the user using an input device such as a remote controller, such as resolution or bit rate, is received (step S2002), and the operation result is stored in a flash memory or the like. Is recorded for holding in the holding unit (step S2003). Then, the information amount of dubbing destination data when dubbing is performed according to the received recording condition is calculated (step S2004), and it is determined whether or not the information amount decreases before and after dubbing as a result of the calculation (step S2005).

  If it is determined that the amount of information is reduced as a result of the determination, erasure priority information is generated so that the dubbing source erasure priority is lowered, for example, assuming that complete dubbing with video quality is not possible (step S2006Y). Also, as a result of the determination in step S2005, if it is determined that the amount of information does not change (increased), for example, the dubbing source has a high priority for erasing, assuming that complete dubbing is performed while maintaining video quality. Erase priority information is generated so as to be (step S2006 N). Then, the video data dubbing process is executed according to the recording conditions (step S2007). Note that the calculation of the information amount of the dubbing destination data in step S2004 may be executed by acquiring the actual recording data amount after the dubbing of data in step S2007.

<Brief description of effect>
As described above, in the video recording apparatus according to the present embodiment, when dubbing is accompanied by a reduction in the amount of information, the priority of erasing the dubbing source data is set as it is not possible to perform complete backup with video quality. Processing such as lowering can be performed. Therefore, for example, the order of erasure candidate list is rearranged according to its priority, or in combination with the video recording apparatus of the other embodiments described above, a predetermined time and the number of scheduled erasures are determined according to the priority. Can do.

Example 5
<Overview>
FIG. 21 is a diagram illustrating an example of a GUI screen related to the video recording apparatus according to the present embodiment. As shown in FIG. 21 (a), episodes 1 to 3 of a continuous drama regularly broadcast on Tuesday at 9:00 are recorded and recorded in the HDD of the video recording apparatus of this embodiment. Of the video data stored and held, “drama second episode” α has been dubbed to the next-generation DVD or the like by dubbing control of the control unit. Then, as shown in FIG. 21 (b), when the video recording apparatus of this embodiment records the next “Drama Episode 4” β, as an overwriting record to the dubbed “Drama Episode 2”. It is characterized by processing. In this manner, in the video recording apparatus of the present embodiment, dubbed data can be erased efficiently by overwriting without the user's trouble.

<Functional configuration>
FIG. 22 is a diagram illustrating an example of functional blocks in the video recording apparatus according to the present embodiment. As shown in this figure, the “video recording apparatus” (2200) of the present example is similar to the first example in that “first recording unit” (2201), “second recording unit” (2202), “ It has a “control section” (2203), a “user interface section” (2204), and a “holding section” (2205). Since these constituent elements are the same as those described in the first embodiment, description thereof will be omitted. In addition, in combination with the other embodiments described above, the configuration requirements such as “first GUI means” described in each embodiment may be further provided. In this embodiment, the user interface unit of the video recording apparatus further includes a “fifth GUI unit” (2206) and a “sixth GUI unit” (2207), and the control unit “overwrite control unit” (2208). ).

  The “fifth GUI means” (2206) has a function of outputting a screen for allowing the user to input reservation information for controlling to repeatedly record update data obtained at predetermined intervals on the recording medium. It can be realized with five GUI programs. Specifically, for example, a reservation input screen for program recording as shown in FIG. In such a scheduled recording of a program, for example, “every Sunday” α or “Monday to Friday” may be designated to record a series of dramas, and a predetermined interval for recording video data repeatedly may be designated. it can. Since the video data group repeatedly recorded in this way is highly relevant, when the latest video data is repeatedly recorded, it is recorded by overwriting the old video data with the following configuration. It is a state of doing.

  In this embodiment, a GUI screen as shown in FIG. 23B may be output instead of the fifth GUI. In this GUI, for example, by accepting a designation input such as “keyword” or “genre”, video data matching the designated keyword can be automatically and repeatedly recorded. However, in this case, the video data that is repeatedly recorded is not necessarily updated at a predetermined interval, but the video data group that is repeatedly recorded by this keyword is also highly relevant. It is good to record by overwriting old video data that has been dubbed.

  The “sixth GUI means” (2207) has a function of outputting a screen for allowing the user to input a command for controlling the dubbing of data from one recording medium to the other recording medium. For example, the sixth GUI program Etc.

  The “overwriting control means” (2208) has a function of performing repetitive recording based on the reservation information as overwriting recording to data that has been subjected to data dubbing control by the control unit, such as an overwriting control program. Can be realized. Specifically, the same identification information is added to the video data group recorded repeatedly based on the reservation information α received by the fifth GUI means and managed in the database. When dubbing control is performed according to the operation result received by the sixth GUI means, a recorded flag or the like is added to the video data in the database for management. When the latest video data based on the reservation information α is recorded, the database is referred to, the video data associated with the identification information of the reservation information α and to which the recorded flag is added is specified, and the video For example, the overwriting process is executed on the data. The “overwriting process” is not only a processing mode in which the recording of the latest video data and the erasure of the specified video data are performed simultaneously, but also the above-mentioned specification is automatically performed immediately after the recording of the latest video data. This is a concept including a processing form such as deleting the video data.

  As described above, in the video recording apparatus of the present embodiment, dubbed data can be efficiently erased without the user's trouble.

<Hardware configuration>
FIG. 24 is a schematic diagram illustrating an example of the configuration of the video recording apparatus when the functional components described above are realized as hardware. The operation of each hardware component in the overwriting process related to repetitive recording will be described using this figure. As shown in this figure, the video recording apparatus includes the “CPU” (2401), “main memory” (2402), “first recording circuit” (2403), HDD, 2 recording circuit "(2404), next-generation DVD and its drive, and the like. In addition, a “flash memory” (2405), a “VRAM” (2406), a “display” (2407), a “light receiver” (2408) for receiving an operation signal from a remote controller, and the like are also provided.

  Here, when the video recording apparatus according to the present embodiment receives the operation signal from the remote controller by the “light receiver”, the fifth GUI screen data is read to the address 1 of the “main memory” accordingly and is transmitted via the “VRAM”. Display on the “Display”. Then, the reservation information for repetitive recording received via the GUI screen as shown in FIG. 23 displayed on the “display”, for example, the designated repetitive date and time, channel information, etc. is stored in the address 2 of the “main memory”. Thereafter, the “CPU” interprets the control program, controls the “first recording circuit” according to the reservation information, and repeatedly records video data received by a “broadcast reception tuner” (not shown) on the HDD or the like. At this time, the video data group repeatedly recorded with one reservation information is associated with the same identification information and managed in a reservation management database (DB) in the “flash memory”.

  In addition to the above processing, when the video recording apparatus of the present embodiment receives the operation signal from the remote controller at the “light receiver”, the sixth GUI screen data is read to the address 3 of the “main memory” accordingly. It is displayed on the “display” via “VRAM”. Then, the dubbing operation command received through the GUI screen is stored at address 4 of “main memory”. Then, the “CPU” interprets the control program and reads the video data designated as the dubbing source from the “HDD” accordingly. Then, the “second recording circuit” is controlled, and the read video data is written to another recording medium such as “next generation DVD”. Further, flag information indicating that the dubbing control has been executed is added to the reservation management database and managed.

  Thereafter, when the latest video data is recorded on the HDD according to the reservation information received via the fifth GUI screen, the “CPU” interprets the overwrite control program and performs the following processing accordingly. That is, with reference to the reservation management database held in the “flash memory”, it is determined by logical operation whether there is an old video data group based on the same reservation information to which dubbed flag information is added. When such video data is specified, the “first recording circuit” is controlled so that the recording of the latest video data is overwritten to the specified video data. .

<Process flow>
FIG. 25 is a flowchart illustrating an example of a processing flow in the video recording apparatus according to the present embodiment. The steps shown below may be steps executed by each hardware configuration of the computer as described above, or may be processing steps that constitute a program for controlling the computer recorded on a medium. I do not care. As shown in this figure, first, the fifth GUI screen is output to the display in accordance with, for example, an operation input from the user (step S2501). Then, according to the fifth GUI screen output and displayed on the display, when the operation result of the reservation information for repetitive recording input by the user with an input device such as a remote controller is received (step S2502), the operation result is stored in the flash memory, for example. Etc. for recording in the holding unit (step S2503).

  In addition to the above processing, for example, the sixth GUI screen is output to the display in response to an operation input from the user (step S2504). Then, according to the sixth GUI screen output and displayed on the display, when the dubbing operation result input by the user with the input device such as a remote control is received (step S2505), this operation result is also held in a holding unit such as a flash memory. Therefore, it is recorded (step S2506). Then, in accordance with this dubbing operation command, the video data of one recording medium is recorded on the other recording medium (step S2507). Then, when performing repetitive recording based on the reservation information held in the holding unit thereafter, it is executed as overwriting to the data dubbed in step S2507 (step S2508).
