Description

METHOD OF PROVIDING MISSING-CATCHABLE REPRESENTATION OF BROADCASTING CONTENTS USING BACKGROUND-STORING IN DIGITAL BROADCASTING RECEIVERS, AND COMPUTER-READABLE RECORDING MEDIUM FOR THE SAME}

The present invention relates to a broadcast reproducing technique for supporting a missing catch function using background storage in a digital broadcast receiving apparatus. More specifically, when a channel is repeatedly changed according to the viewer's preference in a digital broadcasting receiver (eg, digital TV, digital set-top box, digital smart box), the previous channel is automatically stored in the hard disk area in the background. The present invention relates to a broadcast reproducing technology that supports a missing catch function, which enables a user to revisit a selection even when a user misses an important part in the middle of a channel change.

With the rapid development of engineering techniques for digital image compression such as MPEG, H.264 and digital modulation and demodulation such as QPSK and QAM, commercialization of digital broadcasting is rapidly progressing worldwide. Now, each country sets its own schedule, gradually stopping analog broadcasting and completely switching to digital broadcasting.

Such digital broadcasting can compress information data compared to analog broadcasting, and has high transmission speed, excellent sound quality and image quality. In addition, digital broadcasting has the advantage that it is possible to create a plurality of virtual channels in one physical channel through the digital modulation and demodulation technology, which makes it possible to efficiently use broadcast frequencies. Through this, various information can be broadcasted through hundreds of channels, and viewers can receive various services through television.

A broadcast receiving device (eg, digital TV, digital set-top box, or digital smart box) that receives digital broadcasts restores the broadcast program selected by the user to original A / V (Audio / Video) data using a decoder provided in the receiving device. And, by displaying through the internal or external display device allows viewers to watch the broadcast program according to their choice.

Viewers often change channels while watching a broadcast program. If you are interested in watching a program on a particular channel and you are not interested in it for a while, you can change to another channel. Or, if you are broadcasting a program you want to watch on more than one channel, you can't miss both, so you can watch the broadcast by moving back and forth through the channel. Picture-in-picture (PIP) technology was once proposed to aid this situation, but its practical utilization was not high. People are still watching between programs, switching back and forth between two or more channels.

However, if you go back and forth between two channels and watch a broadcast program, you may miss important scenes in the broadcast program. For example, you miss out on the scores of professional baseball, goals in football, boxing downs, and critical events in dramas. Missing these scenes in the broadcast program is not only a pity for the viewer, but also a problem of not properly understanding the future development. As a result, the viewer's interest in the broadcast program is rapidly deteriorated, which is also a loss to the viewer, but the loss is also great because the viewer rating is lowered from the position of the broadcaster or the broadcast service provider (SO).

In order to prevent this situation from falling in the future, the replay service is provided through the Internet homepage in the case of a drama or a survival program. However, the effect is limited. After a certain time elapses, the viewer has to regain his memory and enter the Internet homepage to search for services. Not only is it not easy to raise interest once it has been degraded, but it is not particularly attractive to viewers to watch the scene again after the final result has been achieved in live broadcasts.

As such, the review service through the Internet homepage is not very effective to solve the above problems. Accordingly, there is a need for a new way of developing technology to solve this problem.

Hereinafter, the present invention will be described in detail with reference to the drawings.

1 is a diagram showing an entire system to which the present invention is applied, and FIG. 2 is a block diagram showing an internal configuration of a broadcast receiving device 30 supporting a missing catch function according to the present invention.

The entire system to which the present invention is applied includes a broadcast system 10, a broadcast communication network 20, a broadcast receiving device 30, a remote controller 40, and a display device 50. At this time, the broadcast receiving device 30 includes a broadcast receiving unit 31, a remote control receiving unit 32, a storage unit 33, a control unit 34, the control unit 34 is a broadcast channel setting module 34a, the background storage Module 34b and background output module 34c.

First, the overall system shown in FIG. 1 will be described.

The broadcasting system 10 is a concept that includes a system for transmitting digital broadcasting through the broadcasting communication network 20, and examples thereof include terrestrial broadcasting stations, cable broadcasting companies, satellite broadcasting transmitting systems, and IPTV operators.

The broadcast receiving device 30 is a device for converting a digital broadcast into a form that a viewer can see by wired or wireless, and may include, for example, a digital TV, a digital set-top box, an IPTV, a smart box, and a smart TV.

The remote controller 40 is a device for controlling the functions of the broadcast receiving device 30, and is not limited to the remote controller provided as a package when purchasing the broadcast receiving device 30, and may be a universal remote control or a software remote control (smartphone remote control program). It installs and drives).

The display device 50 is a device for displaying a screen generated by the broadcast receiving device 30 to the viewer, which may be independent of the broadcast receiving device 30 or may be integrated with the broadcast receiving device 30.

Next, the broadcast receiving device 30 disclosed in FIG. 2 will be described.

The broadcast receiver 31 is configured to receive a digital broadcast signal transmitted from the broadcast system 10 through the broadcast communication network 20 and to perform various processing for selecting a specific broadcast channel.

The remote control receiver 32 is configured to receive a wired / wireless control signal provided from the remote controller 40 and identify a control command therefrom.

The storage unit 33 is a component for storing various data, and is preferably implemented as a hard disk (HDD) in consideration of storage capacity and device price. In the present invention, the storage unit 33 supports a background storage function and a missing catch function using the same, which will be described later with reference to FIGS. 3 and 4.

The controller 34 is configured to control the overall operation of the broadcast receiving apparatus 30 to implement the present invention, and includes a broadcast channel setting module 34a, a background storage module 34b, and a background output module 34c. .

The broadcast channel setting module 34a controls the broadcast receiver 31 to receive broadcast content for the channel when a user request for a specific channel is provided through the remote controller receiver 32. It is common for a user to perform a number of channel changes while watching a broadcast program. As such, whenever a channel change request is input through the remote controller receiver 32, the broadcast channel setting module 34a is configured to achieve a channel change according to the request. To control (31).

The background storage module 34b performs background storage on the channel before the change ('previous channel') whenever the broadcast channel is changed. For example, when the user presses the channel-up button on the remote control 40 and requests the change of the broadcast channel from the current CH 6 to the CH 7, the broadcast channel setting module 34a displays the broadcast content for the current channel CH 7. While being displayed on the display device 50, the background storage module 34b implements an operation of storing broadcast data for the previous channel CH 6 in the storage 33 in a background manner. That is, the broadcast data for CH 6, which is a broadcast channel that the user no longer watches, is continuously received and stored for emergency.

The background output module 34c is activated when the user presses the channel down button of the remote controller 40 to return to CH 7 and then requests the missing catch function according to the present invention. The background output module 34c uploads and plays back the broadcast data stored in the background 33 by the background storage module 34b in the storage unit 33 in relation to CH 7 which is a channel that has been returned to the display device 50. do. That is, the background output module 34c means 'a module for outputting data stored in the background method to the display.'

3 is a diagram conceptually illustrating a missing catch function used in the present invention, and FIG. 4 is a block diagram conceptually illustrating an operation of the broadcast receiving apparatus 30 implementing such a missing catch function.

First, referring to FIG. 3, it is shown that the user changed the broadcast channel to CH 6, CH 7, CH 6, CH 7, and CH 8 in chronological order. In other words, channel 6 and channel 7 are alternately moved to channel 8.

Referring to T3, the user recognized that he missed an important scene on channel 6 after changing from channel 7 to channel 6. In other words, while watching channel 6 from T1 and going to channel 7 for a while (T1 → T2 → T3), channel 6 scored professional baseball, goal shots of football, boxing down and important events in drama. There were important scenes such as accident scenes.

In the present invention, in this case, by pressing a specific button (missing catch button) provided in the remote controller 40, a missing catch function may be used. That is, when the user presses the missing catch button, the broadcast receiving device 30 uploads the broadcast data stored in the background at the time T2 for channel 6 so that the missed part can be immediately confirmed. In this specification, since there is no conventional name for a function that enables the user to immediately check a part missed in the channel change process, it is called a 'missing catch' function.

Referring to FIG. 3, when a user changes a broadcast channel to CH 6, CH 7, CH 6, CH 7, CH 8, the broadcast reception device 30 may confirm that the channel immediately before the change is storing in the background. . For example, referring to T2, when the user changes from channel 6 to channel 7, while the user watches the channel 7 after the change, the broadcast receiving device 30 is configured for the channel 6 immediately before the change. The broadcast data is stored in the storage unit 33 in the background.

The background stored broadcast data is utilized when the user requests the missing catch function, otherwise discarded. Referring to T3 and T4, as the user requested the missing catch function, broadcast data about channel 6 and channel 7 stored in the background in T2 and T3 were used, respectively. Meanwhile, referring to T5, since there is no broadcasting data previously stored in the background regarding channel 8, even if a user requests a missing catch function, service is not possible.

Subsequently, referring to FIG. 4, a configuration of the broadcast receiving device 30 for implementing the above missing catch function has been conceptually disclosed.

First, the broadcast receiver 31 includes not only a current channel receiver 31a for receiving a broadcast signal for a current channel but also a previous channel receiver 31b for receiving a broadcast signal of a previous channel for background storage. do. In the present invention, there may be a plurality of channels to be stored in the background. In this case, a plurality of previous channel receivers 31b are also provided.

For example, when the user views channel 8 at T5, the background storage module 34b may store only the immediately preceding channel 7 times, but may configure the previous channel 6 to be stored in the background. When the plurality of channels are to be stored in the background, a plurality of previous channel receivers 31b must be provided, and the background storage space 33a of the storage 33 must be set to match the number of channels to be stored in the background. The background storage module 34b may set the number of storage for the previous channel content according to the multi-channel broadcast reception performance of the broadcast receiver 31 and the storage space capacity of the storage 33.

Subsequently, the storage unit 33 has a background storage space 33a and a foreground utilization space 33b. The background storage space 33a is a space for the background storage module 34b to store broadcast data received from the previous channel receiver 31b in a background manner. Since the storage space allocated for the broadcast data backup is finite, it is desirable to operate the storage space in a ring structure in order to use it efficiently. By operating the storage space in a ring structure, it guarantees a backup of the latest fixed time (eg 10 minutes) and the previous broadcast data is deleted by overwriting.

The foreground utilization space 33b is a space used by the background output module 34c and is utilized when the sewing machine catch function is used. That is, referring to T3 in FIG. 3, the background storage space 33a is a space for background storage of broadcasting data currently being input for channel 7, and the foreground utilization space 33b supports a sewing catch function. This is a space for uploading and reproducing broadcast data stored in the previous (T2) channel 6. Optionally, when the missing catch function is enabled, broadcast data previously stored in the background for the channel is uploaded and reproduced in the foreground utilization space 33b, and the broadcast data currently being input for the current channel is also pore. It is also preferable to prevent the user from being missed by storing it in a predetermined area of the ground utilization space 33b.

5 is a flowchart illustrating the overall process of the missing catch support broadcast reproduction method according to the present invention. Since the technical matters of the present invention have been described in detail with reference to FIGS. 1 to 4, the overall flow of the process will be described with reference to FIG. 5.

First, the user starts the broadcast receiving device 30, and performs the setting related to the missing catch function according to the present invention (S110). As a setting for the missing catch function, a selection of whether or not to use the missing catch function and a selection of how many broadcast channels are to be stored in the background can be considered. Since the storage capacity of the background storage space 33a is limited, as the number of broadcast channels to be stored in the background increases, the time covered by the missing catch function will decrease. In some implementations, as the number of broadcast channels increases, the video quality may be degraded and stored in the background.

Next, as the user selects the broadcast channel to watch through the remote controller 40, the broadcast receiving device 30 receives the digital broadcast through the broadcast communication network 20 and displays it on the screen of the display device 50 (S120). ).

Subsequently, the remote controller 40 waits for a broadcast channel change request (S130).

When the user requests a broadcast channel change through channel up / down, the broadcast receiving device 30 receives a digital broadcast for the changed channel (current channel) and displays it on the screen of the display device 50 (S140). .

At this time, the background storage module 34b of the broadcast receiving device 30 stores the digital broadcast data for the channel (previous channel) before the channel change in the background in the background storage space 33a (S150). This background storing operation is performed for the previous channel whenever the user changes the broadcast channel.

Subsequently, the broadcast receiving device 30 determines whether a missed catch request is provided from a user (S160). When the user presses, for example, a missing catch button provided on the remote controller 40, the broadcast receiving device 30 receives a missing catch request. If there is no missing catch request, the display device 50 displays the broadcast screen for the current channel as in the related art.

On the other hand, when there is a missing catch request, the broadcast receiving device 30 enables the missing catch function and accordingly performs a function of supporting a user to check a missing part of the current channel. That is, the background output module 34c uploads and reproduces the broadcast data stored in the background before the channel change by the background storage module 34b for the current channel (S170).

Then, the broadcast receiving device 30 is provided by waiting for the missing catch release request from the user (S180).

Upon receiving the missed catch release request, the broadcast receiving device 30 disables the missing catch function and displays the digital broadcast data provided in real time on the current channel in the display device 50 in a general manner (S190).

6 is a flowchart illustrating another embodiment of a missing catch support broadcast reproduction method according to the present invention. Since the technical matters of the present invention have been described in detail with reference to FIGS. 1 to 5, the overall flow of the process will be described with reference to FIG. 6.

First, the user activates the broadcast receiving device 30 and performs a setting relating to the missing catch function according to the present invention (S210). The sewing catch function setting can be selected as to whether or not to use the missing catch function, how many broadcast channels are to be stored in the background, and the like as described in FIG. 5.

Next, as the user selects the broadcast channel to watch through the remote controller 40, the broadcast receiving device 30 receives the digital broadcast through the broadcast communication network 20 and displays it on the screen of the display device 50 (S220). ).

Subsequently, the remote controller 40 waits for a broadcast channel change request (S230).

When the user requests to change the broadcast channel through channel up / down, the broadcast receiving device 30 receives a digital broadcast for the changed channel (current channel) and displays it on the screen of the display device 50 (S240). .

At this time, the background storage module 34b of the broadcast receiving device 30 stores the digital broadcast data for the channel (previous channel) before the channel change in the background storage space 33a in the background (S250). This background storing operation is performed for the previous channel whenever the user changes the broadcast channel.

Subsequently, the broadcast receiving device 30 determines whether a missing catch request is provided from a user (S260). When the user presses, for example, a missing catch button provided on the remote controller 40, the broadcast receiving device 30 receives a missing catch request. If there is no missing catch request, the display device 50 displays the broadcast screen for the current channel as in the related art.

On the other hand, when there is a missing catch request, the broadcast receiving device 30 enables the missing catch function and accordingly performs a function of supporting a user to check a missing part of the current channel. However, in the present embodiment, it is determined whether the change of the broadcast channel is made in an alternating manner (S270). An alternating pattern is an alternating form alternately between two channels. For example, a channel change made in T1 to T4 in FIG. 3 corresponds to an alternating pattern. On the other hand, the channel change of T5 in FIG. 3 does not correspond to an alternating method.

If it is determined in step S270 that the channel is not changed in the alternating manner, the service does not provide the missing catch request and ignores it. This embodiment corresponds to a case of supporting background storage only for one channel, and may be implemented when it is determined to be optimal in consideration of the performance of the broadcast receiving device 30. That is, since only one channel is supported for background storage, if there is no alteration method, there will be no broadcasting data stored in the background, so the missing catch request is ignored.

On the other hand, in the case of the channel change of the alternating method as a result of the determination in step S270, the background output module 34c uploads and plays the broadcast data stored in the background before the channel change by the background storage module 34b for the current channel. (S280).

In the present embodiment, the background output module 34c supports user control of the playback point and playback speed. That is, the user can control the playback time and the playback speed as the user presses a button, for example, a four-way button, pre-assigned on the remote controller 40. Of the broadcast data stored in the background storage space 33a, it is unknown at which point the user wants to catch the important scene, and the connection with the broadcast data currently input to the channel in real time must be taken into consideration, so the background output module 34c is played back. It is desirable to support control of the timing and playback speed.

Then, the broadcast receiving device 30 is provided by waiting for the missing catch release request from the user (S300).

Upon receiving the missed catch release request, the broadcast receiving device 30 disables the missed catch function and displays the digital broadcast data provided in real time on the current channel in the display device 50 in a general manner (S310).

The present invention can also be embodied in the form of computer readable code on a computer readable recording medium. At this time, the computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored.

Examples of the computer-readable recording medium include a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, an optical data storage, and the like, and may be implemented in the form of a carrier wave . The computer-readable recording medium can also be stored and executed by a computer-readable code in a distributed manner on a networked computer system. And functional programs, codes, and code segments for implementing the present invention can be easily deduced by programmers skilled in the art to which the present invention belongs.

As described above, the embodiments of the present invention have been disclosed in the present specification and drawings, and although specific terms have been used, they have been used only in a general sense to easily describe the technical contents of the present invention and to facilitate understanding of the invention. And is not intended to limit the scope of the invention. It will be apparent to those skilled in the art that other modifications based on the technical idea of the present invention are possible in addition to the embodiments disclosed herein.
