Description
The present application claims priority to the filing of japanese patent application having application number 2020-.
The present invention relates to a receiving apparatus having a video recording function and a sound recording function, and a nonvolatile storage medium.
Conventionally, video recorders that receive broadcast waves and record programs have been widely used. In recent years, receiving devices such as televisions having a video recording function and a sound recording function have been proposed. In order to realize such a video recording function, a large-capacity storage medium such as a Hard Disk Drive (HDD) or a solid state drive (SDD) is required. In a receiving apparatus having a video recording function and a sound recording function, there has been proposed a configuration in which a storage medium is externally connected without being built in the receiving apparatus, and a user can connect an arbitrary storage medium.
The performance of storage media is increasing and users may also reuse older storage media. This means that the performance of the storage medium connected to the receiving device is unknown. On the other hand, the performance of the storage medium may depend on the bit rate and the recording function of the program received by the receiving apparatus. Therefore, in the case where the storage medium of the receiving apparatus is configured to be freely selectable by the user, it is necessary to suppress the video recording performance and the like so that any storage medium can be handled. However, the performance of the storage medium and the performance of the video recording function cannot be fully exhibited.

(embodiment 1)
Hereinafter, embodiments will be described in detail with reference to the drawings. As shown in fig. 1, a receiving apparatus 1 according to embodiment 1 is, for example, a digital television receiving apparatus having a video recording function. The receiving apparatus 1 includes: an antenna 11, a tuner 12, a demultiplexing module 13, a storage control module 14, an interface (I/F)15a, an input section 15b, a storage device (HDD)16, a video decoder 17, an audio decoder 18, an image processing module 19, a voice processing module 20, a display section device 21 capable of displaying a digital video signal, and a speaker 22 having a D/a conversion function and capable of outputting a digital voice signal.
The tuner 12 is a circuit block for selecting a desired broadcast wave (broadcast station) from, for example, a digital broadcast wave acquired by the antenna 11. The broadcast wave is not limited to being acquired from an antenna, and may be acquired from a cable television station or the like via a cable. The demultiplexing module 13 is a circuit block that separates and outputs a video signal and an audio signal multiplexed on a broadcast wave to the video decoder 17 and the audio decoder 18, respectively.
The video decoder 17 is a circuit block that decodes the video signal separated by the demultiplexing module 13 and outputs the decoded digital video signal to the image processing module 19. On the other hand, the audio decoder 18 is a circuit block that decodes the voice signal separated by the demultiplexing module 13 and outputs the decoded digital voice signal to the voice processing module 20. The image processing module 19 and the voice processing module 20 are circuit blocks that perform predetermined image processing and voice processing on the decoded digital video signal and digital voice signal, and output the processed video signal and voice signal to the display unit 21 and the speaker 22, respectively.
The storage control module 14 is a circuit block that causes the storage device 16 to store (record) the contents of a broadcast program or the like received before being decoded by the video decoder 17 and the audio decoder 18, and reads (plays) the broadcast program or the like stored in the storage device 16. The storage control module 14 is capable of controlling the storage device 16 via the interface 15 a. Further, the storage control module 14 can cause the display section device 21 to display an image display for the user, receiving an instruction of the user from the input section 15 b.
The storage device 16 is, for example, a hard disk drive device, an optical disk drive device capable of writing to a recording-type optical disk, or the like. The storage device 16 can record a broadcast program or the like by control from the storage control module 14. The interface 15a is, for example, an interface of the USB standard, and connects the input unit 15b and the storage device 16 to the storage control module 14.
The storage device 16 may be an external storage device such as a DVD (registered trademark) recorder or an external HDD, or may be an internal storage device such as a built-in HDD or a flash memory. The storage device 16 can be arbitrarily selected by the user and connected to the interface 15 a.
The input unit 15b is an interface that receives an instruction from a user and converts the instruction into an instruction signal, such as a switch or a touch panel disposed in the housing, and is connected to the memory control module 14 via the interface 15 a.
Next, the structure of the storage control module 14 will be described in detail with reference to fig. 2. As shown in fig. 2, the storage control module 14 of the embodiment includes: an HDD detection unit 141, a performance measurement unit 142, a determination unit 143, an operation setting unit 144, a setting storage unit 145, and a recording/playback processing unit 146.
The HDD detection unit 141 is an arithmetic block that detects connection of the storage device 16. When detecting the connection of the storage device 16, the HDD detection unit 141 sends the detection result to the performance measurement unit 142. The performance measurement unit 142 is an operation block that measures the performance of the storage device 16 connected to the interface 15. When HDD detection unit 141 detects connection of a new storage device and when an instruction for performance measurement is received from the user via input unit 15b, performance measurement unit 142 performs a performance test of storage device 16. As the performance test of the storage device 16, a write rate, a read rate in writing, and the like of the storage device as a target are exemplified. In particular, the read rate in writing indicates the performance of a function for simultaneously performing a writing operation and a reading operation to a storage device.
The determination unit 143 is an operation block that determines the performance of the storage device 16 connected to the interface 15 based on the measurement result of the performance measurement unit 142. The determination unit 143 determines a video recording/playing function (for example, any one or more of a video recording function, a playing function, a transfer function, a simultaneous video recording/playing function, a dubbing (dubbing) function, a video recording/simultaneous distribution function, a function of writing/reading contents into/from a storage medium, and a function realized by combining the writing function and the reading function) suitable for a receiving apparatus of the storage apparatus 16, based on the performance (write rate, read rate during writing, and the like) of the storage apparatus 16. The operation setting unit 144 is an arithmetic block for setting the recording/playback function, the recording mode, and the like of the receiving apparatus 1 based on the determination result of the determining unit 143 and storing the setting in the setting storage unit 145. The setting storage unit 145 is a memory for storing setting information and the like set by the operation setting unit 144. The recording/playback processing unit 146 is an operation block that records and records content in the storage device 16 and reads and plays back the recorded content.
(operation of receiving apparatus)
Next, the operation of the receiving apparatus 1 according to the embodiment will be described with reference to fig. 2 to 8. The following description is an operation example in the case where a hard disk device is newly connected to the interface 15a as the storage device 16. In the following description, the write rate and the read rate during writing are measured as the performance of the storage device, and the video recording function and the simultaneous video recording and playing function are determined as the video recording and playing function of the receiving device.
(selection of storage device)
The HDD detection unit 141 monitors connection of a new storage device 16 (storage medium) via the interface 15. When a new storage device 16 is detected, the HDD detection unit 141 displays an image for prompting selection of the storage device 16 to be subjected to the performance test on the display unit device 21 via the demultiplexing module 13 or the like. The user selects a storage device to be tested through the input unit 15b in accordance with the display of the display unit device 21 (S300).
Fig. 4 is an example of image display displayed on the display unit device 21. As shown in fig. 4, the image display 300 shows "hard disk 1" as the registered name of the storage device 16, and shows "connected" as the connected state. When the user selects "hard disk 1" via the input unit 15b (shown in a black frame in fig. 4) and selects "determination" of the two commands 302a "determination" and "return", the performance measurement unit 142 receives an instruction signal for determining the storage device 16 to be tested.
(Performance test of storage device)
Upon receiving the instruction signal for specifying the storage device 16, the performance measurement unit 142 performs a performance test on the specified storage device 16 (in the example of fig. 4, "hard disk 1") (S302).
Fig. 7 is a flowchart showing an example of the performance test. In the example shown in fig. 7, the write rate and the read rate during writing of the target storage device are measured. By testing these two performances, it is possible to determine the write speed that can be performed by the memory device and the read speed that can be performed during writing. (S320)
As a result of the test, when the write rate of the storage device 16 is less than 33Mbps (yes in S322), the determination unit 143 determines that the storage device 6 does not have the capability of withstanding the 4K video recording (S324). When the write rate is 33Mbps or more (no in S322) and the read rate during writing is less than 24Mbps (yes in S326), the determination unit 143 determines that the storage device 16 can only perform 4K video recording (S328).
As a result of the test, when the write rate of the storage device 16 is 33Mbps or more (no in S322) and the read rate during writing is less than 33Mbps (yes in S330), the determination unit 143 determines that the storage device 16 can record 4K video and play 2K simultaneously (S332). When the write rate is 33Mbps or more (no in S322) and the read rate during writing is 33Mbps or more (no in S330), the determination unit 143 determines that the storage device 16 can record 4K video and play 4K simultaneously (S334).
(display of Simultaneous action Specifications)
The operation setting unit 144 displays the determination result of the determining unit 143 on the display unit device 21 via the demultiplexing module 13 (S304). Fig. 5 is an example of the determination result displayed on the display unit device 21. The display unit device 21 displays the determination result 302b of the determination unit 143, the simultaneous operation specification 304 to be set by the operation setting unit 144, and the command 306b as an image display 306 a. In the example shown in fig. 5, the determination result 302b indicates that the storage device 16 has the capability of performing 4K recording and 2K simultaneous playback, and as the simultaneous operation specification 304, three simultaneous operation specifications of 4K-only recording, 4K-only playback, 4K-only recording, and 2K simultaneous playback are indicated to the user. The simultaneous operation standard is a video recording function for simultaneously performing writing and reading to and from the storage device, and is different depending on the performance of the storage device. Generally, a load of performing operations of writing and reading to and from a storage device at the same time is high, and is used as an operation index of the storage device in a video recording function.
When the user selects "update setting" as the command 306b via the input unit 15b (yes at S306), the operation setting unit 144 stores the content of the simultaneous operation specification 304 displayed on the display unit device 21 in the setting storage unit 145 (S308). This is data indicating the maximum video recording function that can be performed when the recording/playback operation is performed by the recording generation processing unit 146. When the user selects "return to the previous screen" as the command 306b (no in S306), the performance measuring unit 142 moves to the previous screen shown in fig. 4 and stands by for an instruction of the performance test.
(Performance test in video mode)
The receiver 1 according to the embodiment may perform the performance test and determination of the settable video recording mode as the performance test of the storage device 16, together with the simultaneous operation specification shown in fig. 7 or independently of the simultaneous operation specification shown in fig. 7 (S310). Fig. 8 shows an example of a performance test relating to the recording mode, specifically, a reading rate in 4K recording is measured.
AS shown in fig. 8, when the performance measurement unit 142 performs the performance test related to the recording mode (S340), and when the reading rate in 4K recording of the storage device 16 is less than 12Mbps (yes in S342), the determination unit 143 determines the recording mode that can be set by the storage device 16 AS "(S344). When the read rate in 4K recording is less than 24Mbps (yes in S346), the determination unit 143 determines that the recording mode settable in the storage device 16 is "AN" (S348). When the read rate in 4K recording is less than 33Mbps (yes in S350), the determination unit 143 determines the recording mode that can be set by the storage device 16 as "AF" (S352). When the read rate in 4K recording is 33Mbps or more (no in S350), the determination unit 143 determines the recording mode of the storage device 16 as "DR" (S354).
(display of video mode)
The operation setting unit 144 displays the determination result of the determining unit 143 on the display unit device 21 via the demultiplexing module 13 (S312). Fig. 6 is an example of the determination result displayed on the display unit device 21. The display unit device 21 displays the determination result 302c of the determination unit 143, the recording mode 312 to be set by the operation setting unit 144, and the command 314b as an image 314 a. In the example shown in fig. 6, the determination result 302c indicates that the recording mode has a performance of 4K video recording and a playable bit rate of 30Mbps as the measurement result of the storage device 16, and it is preferable to present each of the modes of DR mode for 2K video recording, AF mode for 4K video recording, and AF mode for 8K video recording to the user as the video recording mode (S312).
When the user selects "update setting" as the command 314b via the input unit 15b (yes at S314), the operation setting unit 144 stores the contents of the recording mode 312 in the setting storage unit 145 (S316). When the user selects "return to the previous screen" as the command 314b (no in S314), the performance measuring unit 142 moves to the previous screen shown in fig. 4 and stands by for an instruction of the performance test.
In this way, the receiving apparatus according to the embodiment presents the simultaneous operation specification and the video recording mode updated in accordance with the result of the performance test of the storage apparatus to the user. This enables the setting of a recording function and the setting of a recording mode according to the performance of a connected storage device (storage medium).
(embodiment 2)
Next, the operation of embodiment 2 will be described with reference to fig. 2 to 9. The reception device according to embodiment 2 is added with a step of inquiring a user in addition to the operation of the reception device according to embodiment 1. The functional configuration of the receiving apparatus according to embodiment 2 is common to embodiment 1 shown in fig. 1 and 2. In the following description, the same reference numerals are given to the same components and operations as those of embodiment 1, and redundant description is omitted.
(selection of HDD)
The HDD detection unit 141 monitors the connection of the new storage device 16 via the interface 15. When a new storage device 16 is detected, the HDD detection unit 141 displays an image for prompting selection of the storage device 16 to be subjected to the performance test on the display unit device 21 via the demultiplexing module 13 or the like. The user selects a storage device to be tested through the input unit 15b in accordance with the display of the display unit device 21 (S300).
Fig. 10 is an example of image display displayed on the display unit device 21. As shown in fig. 10, the image display 360 displays "hard disk 1" as the registration name of the storage device 16 and displays "connected" as the connection state. When the user selects "hard disk 1" via the input unit 15b (shown in a black frame in fig. 10) and selects "determination" of the two commands 302a "determination" and "return", the performance measurement unit 142 receives an instruction signal for determining the storage device 16 to be tested.
(Performance test of storage device)
Upon receiving the instruction signal for specifying the storage device 16, the performance measurement unit 142 performs a performance test on the specified storage device 16 (S302). The content of the performance test is the same as that of embodiment 1.
(display of Simultaneous action Specifications)
The operation setting unit 144 displays the determination result of the determining unit 143 on the display unit device 21 via the demultiplexing module 13 (S304). Fig. 11 is an example of the determination result displayed on the display unit device 21. The display unit device 21 displays the determination result 362b of the determination unit 143, the simultaneous operation candidates 364b set by the operation setting unit 144, and the command 366 as an image display 364 a. In the example shown in fig. 11, "record 1 only broadcast" in which only one broadcast is recorded, "W record" in which two different programs are recorded simultaneously, "W record + play" in which two different programs are recorded simultaneously and a recorded program is played, "W record + play" in which two different programs are recorded simultaneously and a dubbing is performed and a recorded program is further played is exemplified as a selection candidate of the recording function. These selection candidates are also determination results 362b and are also setting candidates for the simultaneous operation specification 364 b. The determination unit 143 in the candidate simultaneous operation specification 364b determines that the candidate is the most appropriate to be given a flag ("recommended").
(user's selection acceptance)
At the stage when the simultaneous operation specification is displayed, the user can select any one of the selection candidates displayed on the display unit device 21 through the input unit 15b (S305). In the example shown in fig. 11, "W recording + play" is selected (shown in the black box in fig. 11). Then, the user selects the command 366 displayed on the display unit device 21 (S306).
When the user selects "update setting" as the command 366 via the input unit 15b (yes at S306), the operation setting unit 144 stores the specification selected by the user from the simultaneous operation specifications 364b displayed on the display unit device 21 in the setting storage unit 145 (S308). This is data indicating the maximum video recording function that can be performed when the recording/reproducing processing unit 146 performs the video recording/reproducing operation. When the user selects "return to the previous screen" as the command 366 (no at S306), the performance measuring unit 142 moves to the previous screen shown in fig. 10 and stands by for an instruction of a performance test.
(Performance test in video mode)
In the receiving apparatus according to embodiment 2, as the performance test of the storage apparatus 16, the performance test and determination of the suitability of the recording mode may be performed together with the simultaneous operation specification shown in fig. 7 or independently of the simultaneous operation specification shown in fig. 7 (S310). The specific performance test is the same as in embodiment 1.

The operation setting unit 144 displays the determination result of the determining unit 143 on the display unit device 21 via the demultiplexing module 13 (S312). Fig. 12 is an example of the determination result displayed on the display unit device 21. The display unit device 21 displays the determination result 362c of the determination unit 143, the recording mode 374b to be set by the operation setting unit 144, and the command 376 as the image display 374 a. In the example shown in fig. 12, the determination results 362c "AS (8 Mbps)", "AN (12 Mbps)", "AF (24 Mbps)", "DR (no transcoding)" are exemplified AS selection candidates. These are also the determination results 362c and are also setting candidates for the recording mode 374 b. The judgment result corresponds to the video quality. The determination unit 143 determines the most suitable candidate among the recording modes 374b as the setting candidates to be given a flag ("recommended").
(user's selection acceptance)
While the video recording mode is displayed, the user can select any one of the selection candidates displayed on the display unit device 21 through the input unit 15b (S313). In the example shown in fig. 12, "AF (24 Mbps)" is selected (shown in the black frame in fig. 12).
When the user selects "update setting" as the command 376 via the input unit 15b (yes at S314), the operation setting unit 144 stores the mode selected by the user from among the video recording modes 374b displayed on the display unit device 21 in the setting storage unit 145 (S316). When the user selects "return to previous screen" as the command 376 (no at S314), the performance measuring unit 142 moves to the previous screen shown in fig. 10 and stands by for an instruction of the performance test.
In this way, the receiving apparatus according to this embodiment is configured to present a plurality of candidates to the user for the video recording function and the video recording mode determined based on the result of the performance test of the storage apparatus, and the user can select from among the candidates. Thus, it is possible to realize a video recording function setting and a video recording mode setting according to the performance of the connected storage device while adding the user's intention.
