Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / playback system for recording or playing a broadcast program in a storage device capable of random access to moving images, and more particularly, by utilizing the free space of the storage device of this recording / playback system. Accumulate CM programs
Regarding the function to search.

[0002]

2. Description of the Related Art In conventional CM programs, only video and audio are broadcast, and it has been very difficult for a viewer to select and store CM programs and retrieve and reproduce them as necessary. From the standpoint of a program provider, it is desired that when a CM program recorded with a normal program is played back, it should be replaced with the latest CM program at the time of playback, but this is also difficult. there were.

In recent years, it has become possible to broadcast not only video and audio but also information incidental to a program by data broadcasting using a part of analog broadcasting waves such as character information and digital broadcasting. For CM programs, it is possible to broadcast and receive the supplementary information, and it is possible to store it as long as a recording medium is prepared.

Conventionally, as a recording medium for accumulating video and audio of a program, that is, recording, in a general home,
A magnetic tape represented by the VHS method has been used. However, in order to play back the program recorded on the magnetic tape, it was necessary to send the tape to the recording location by fast-forwarding or rewinding, which took a very long time. Also, since the storage capacity per medium is small, the free capacity for recording CM programs is not so large. Also, because the storage capacity is small,
The recording medium is frequently exchanged every time recording or playing, and CM
Even if a program is automatically recorded, it cannot be searched immediately unless the recording medium used for recording is set when needed.

On the other hand, in a storage device using a disk-type recording medium such as a magnetic disk or an optical disk, the cost per storage capacity is currently high, but by moving the recording / reproducing head in the radial direction, it is possible to arbitrarily Since data can be read and written in a short time, the desired program can be started to be reproduced in a short time.

In particular, the magnetic disk device can read / write data at any position on the recording surface by moving the read / write head in the radial direction while keeping the disk rotation speed constant.

On the other hand, in the case of the optical disk device, since the read / write head has a large mass, the seek time of the head is long, and since the allowable linear velocity relative to the medium is narrow, the optical disk device moves largely in the radial direction. In this case, it may take time to accelerate or decelerate the rotation speed of the disk.

This difference also affects quietness, power consumption, and device size. Therefore, it can be said that the magnetic disk device is more suitable for applications in which random access is frequently performed. Further, since the magnetic disk has a storage capacity per recording medium larger than that of the optical disk, the frequency of exchanging the recording medium is small. In this way, data such as video and audio can be randomly accessed at high speed,
And by applying a large-capacity magnetic disk to a recording medium, recorded programs can be instantly searched and played, or multiple programs including the searched programs can be seamlessly spliced together and played. Expected to be possible.

[0009] By the way, in general, since the tastes and demands of viewers are wide, various CM programs are broadcast. Although the length of a CM program is shorter than that of a normal program, the point that the CM program is occasionally interrupted may be neglected. However, it is also true that it affects our lives and values in various ways. It is considered that the value can be increased if a user can extract and listen to a TV program that matches his / her lifestyle and interests from the various commercial programs.

[0010]

However, in addition to automatically accumulating and retrieving the CM programs that one needs, based on the preferences that can be registered in advance, the residential area, etc., the broadcasted CM programs can also be retrieved. It was also very difficult to accumulate everything and find it by browsing from there.

On the other hand, from the point of view of the broadcast provider, the conventional method of broadcasting a CM program to all viewers is wasteful because only some viewers accept the information. I can say.

Further, even if the CM program is recorded together with the normal program, only the CM at the time of recording is reproduced every time it is reproduced thereafter. From the point of view of the broadcast provider, it is desired that this be replaced with the latest CM program and played back, but this was not possible.

From the viewpoint of a recording medium for accumulating CM programs, even if each CM program has a length of about 10 to 20 seconds, it is possible to record all CM programs that are variously and repeatedly broadcast. Requires a huge amount of storage capacity, but it was not possible to make a selection such as recording only the required CMs or not recording CM programs that were repeatedly broadcast.

An object of the present invention is to put a CM in an empty area of a storage device.
A program and its accompanying information are automatically recorded so that they can be easily searched and browsed. Another object of the present invention is to select a CM program that suits a viewer's taste or a CM program recommended by a broadcaster, and record a more useful CM program in a smaller storage capacity range. Still another object of the present invention is to allow a CM program inserted into a normal program to be automatically updated after recording, or a CM program to be newly inserted.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 shows a basic configuration example of a program recording / playback system. The reception signal 20 is a signal in which a plurality of signals are frequency-multiplexed. Tuner 1
Is a signal 21 of a specified frequency from the received signal 20.
Is input to the demultiplexer 2. In the signal output from the tuner 1, not only one or more programs but also various types of packets are time-division multiplexed.

The type of packet is distinguished by an identification number. Each packet is roughly divided into a packet containing a list of correspondences of identification numbers for each program like a program table and a packet relating to the program itself. Further, the latter packet of the program itself contains video and audio of the program. Packet 22
And the packets 23 containing the incidental information of the program. The demultiplexer 2 extracts and outputs the packet designated by the identification number from the signals multiplexed into the input signal 21 as a packet.

The disk device 3 respectively receives a video / audio packet 22 which is a signal including video and audio of a program extracted by the demultiplexer 2 and an auxiliary information packet 23 which is a signal including auxiliary information of this program. It is stored in the program file 10 and the program supplementary information table 11.

The video / audio output means 4 decodes the video / audio packet 22 output from the demultiplexer 2 or the disk device 3 and outputs analog video and audio 24 to the viewer 5.

Next, the basic operation of this program recording / playback system will be described. When the viewer 5 activates the program recording / playback system, the program recording / playback system displays the program currently being broadcast. To display the program currently being broadcast, the video / audio output means 4 decodes the video / audio packet 22 output by the demultiplexer 2. Here, if the viewer 5 requests recording of the program currently being broadcast, the disk device 3 causes the video / video extracted by the demultiplexer 2 to be recorded.
The voice packet 22 is stored on the disc.

By viewing the content of the program supplementary information table 11, that is, the supplementary information packet 23, the viewer 5 refers to what program is recorded in the disk device 3 and commentary information of the program. be able to. If the viewer 5 requests the disc device 3 to reproduce the recorded program, the disc device 3 reads the video / audio packet 22 from the program file 10 and reproduces the video / audio packet 22.
It is decoded by the audio output means 4 and displayed to the viewer 5.

FIG. 2 shows a configuration example of an embodiment of the present invention. In addition, in the following description, it is assumed that incidental information is also broadcast for CMs. The normal program incidental information table 12 stores incidental information of recorded ordinary programs and a correspondence relationship between the incidental information and the program file 10. cm
In the program supplementary information table 13, recorded CM programs and their supplementary information as shown in FIG. 5 are stored together with their corresponding relationship.

As shown in FIG. 6, the recording condition table 14 is a table in which items and contents of incidental information when determining whether or not to record a CM program are described.
CM programs can be registered. Recording condition table 14
Examples of the search condition registered in are the search condition 41 specified by the viewer 5, and the search condition described in the normal program supplementary information table 12 or the CM program supplementary information table 13.

As shown in FIG. 7, the reproduction condition register 15 is a register that describes the items and the contents of the incidental information when determining whether or not to reproduce the CM program. Here, the search condition of the CM program that the viewer 5 desires to reproduce, or the normal program currently being received or reproduced, desires to be reproduced.
One of the search conditions of the CM program is temporarily stored.

The CM program recording determination means 6 sets the program incidental information packet 23 of the received CM program in the recording condition table 14
The recording request signal 43 is output so as to record the received CM program if the recording condition 25 is output.

The CM program reproduction judging means 7 compares the CM program supplementary information table 13 with the reproduction condition 26 output from the reproduction condition register 15, and if there is a match, it responds.
The reproduction request signal 44 of the CM program is output.

Next, the operation of the program recording / playback system according to the embodiment of the present invention shown in FIG. 2 will be described. First, a case will be described in which a CM program desired by a viewer is automatically recorded or searched. In order to automatically record the CM program desired by the viewer 5, first, the viewer 5 starts the desired CM.
The program search condition 41 is registered in the recording condition table 14.

FIG. 3 shows an example of a user interface that realizes this operation with a menu on the screen and cursor keys of the remote controller. In this example, among various items stored in the incidental information of the CM program, the item that matches the recording condition can be selected from the hierarchical menu.

The flow of processing from the reception of the CM program to the recording of the received CM program is shown in the flowchart of FIG. However, S1 and the like in the following sentences represent steps in the flowchart. When it is detected that the reception of the CM program is started (S1), it is checked whether it is explicitly recorded by reservation or manually (S2).

If it has been explicitly recorded, jump to S6 and record the CM program. If it is not explicitly recorded, the CM program supplementary information is acquired (S3), compared with the CM program recording condition table (S4), and it is detected whether they match (S5). For example, a CM program is recorded (S6). Finally, the CM program incidental information is registered in the CM program incidental information table (S7).

The CM program recording determination means 6 first obtains the program incidental information packet 23 from the demultiplexer 2, compares this with the search condition registered in the recording condition table 14, and determines that they match and the disc If the device 3 has sufficient free space, a recording request 43 is issued to record this CM program.

Another implementation method is for the broadcaster to also describe the broadcast schedule of the CM program in the program guide. As a result, the time and frequency at which the CM program registered in the recording condition table 14 is broadcast can be known, so if there is no need to make another recording at that time, the tuner 1 automatically selects this CM program. Can be recorded.

In order to search and reproduce the CM program desired by the viewer 5, the viewer 5 first registers the search condition 42 of the desired CM program in the reproduction condition register 15. FIG. 4 is an example of a user interface for realizing this operation with a menu on the screen and a cursor key of the remote controller. When a selection condition is input on this reproduction CM selection screen, it is set in the reproduction condition register 15 and searched immediately, and a list is displayed on this reproduction CM selection screen.

The flow of processing for reproducing the recorded CM program is shown in the flowchart of FIG. However, S11 and the like in the following sentences represent steps in the flowchart. It is detected whether or not the CM program reproduction condition register is updated (S11), and if it is updated, the CM program reproduction condition register and the CM program supplementary information table are compared (S1).
2) It is detected whether or not they match (S13).

If they match, it is detected from the search result whether or not a CM is selected (S14). If so, the viewer is made to select a CM program to be reproduced (S15), and the CM program is reproduced. Yes (S16). If no selection is made in S14,
Jump to S16 and play the CM program.

The CM program reproduction determining means 7 determines whether or not the CM program matching the search condition is recorded in the disk device 3, and the CM program incidental information 27 which is the contents of the CM program incidental information table 13 and the reproduction condition. Search is performed by comparing the contents of the register 15. If found, the matching CM program list is displayed on the playback CM selection screen of FIG. 4, and the disk device 3 is used to play the CM program file selected by the viewer 5.
To the reproduction request 44.

Next, a case will be described in which a CM program desired by the broadcaster is automatically recorded or searched.
By using this function, for example, a broadcaster can broadcast a commercial program that is targeted at an area in advance and record it, and when the commercial program for the whole country is broadcast, the above-mentioned recording is performed. It will be possible to replace the CM program for the reserved area and present it. Similarly, even satellite broadcasting, which has a low broadcasting cost, will be able to broadcast CM programs for the same area as terrestrial broadcasting.

In order for the broadcaster to record the CM program in the disk device 3 in advance, the broadcaster broadcasts the search condition of the CM program desired to be recorded in advance as the supplementary information of the program, and the demultiplexer 2 is set. It is registered in the recording condition table 14 via this. CM program recording determination means 6,
The reception of the CM program matching this search condition indicates that the program accompanying information packet 23 output by the demultiplexer 2
When it is detected from, the recording request 43 is transmitted to the disk device 3 so as to record the CM program as a program file.

Another implementation method is that the broadcaster requests the viewer to register the residence area or taste in the recording condition table 14 as the search condition 41 in advance, and when the CM program is broadcast, the CM is broadcast. This is a method of broadcasting the audience's living area and taste targeted by the program together as supplementary information of the CM program. As a result, when the CM program recording determination unit 6 detects from the program ancillary information packet 23 output by the demultiplexer 2 that the CM program matching the search condition is received, the CM program is recorded in the disk device 3. A recording request 43 is transmitted so as to record as a program file.

To replace the CM program broadcast by the broadcaster with the CM program in the disk device 3, the following procedure is performed. When broadcasting a CM program, the broadcaster broadcasts the search condition for specifying the CM program prerecorded as described above, as additional information of the CM program to be broadcast. When this search condition is output from the demultiplexer 2, it is registered in the reproduction condition register 15. CM program reproduction judgment means 7
Causes the disk device 3 to reproduce the program file 10 of this CM if it exists. If the program file of this CM is not in the disk device 3, the broadcasted CM program is displayed as it is.

Finally, a case will be described in which a CM program desired by a program provider is automatically recorded or searched. By using this function, for example, when a normal program recorded by a viewer includes a CM program, it is possible to replace the CM program with the latest CM program when the program is reproduced.

The program provider records the CM program in the disk device 3 in advance as follows. The program provider broadcasts, as incidental information of the CM program, a recording condition for recording the latest version of the CM program and a reproduction condition for reproducing the latest version. When the demultiplexer 2 detects this recording condition, the detected recording condition is registered in the recording condition table 14. When it is detected from the program ancillary information packet 23 output from the demultiplexer 2 that the CM program recording determination means 6 has received the CM program that matches this search condition (recording condition), A recording request 43 is transmitted to record the received CM program as a program file.

The reproduction in which the previously recorded CM program is replaced with the CM program desired by the program provider is performed as follows. When the CM program is reproduced, if the supplementary information of the CM program includes the reproduction condition, the reproduction condition is registered in the reproduction condition register 15. The CM program reproduction judging means 7 reproduces the CM program file 10 if the disk device 3 has the program file 10. If the CM program file 10 is not in the disk device 3, the recorded CM program is displayed as it is.

FIG. 10 shows a state in which a normal program and a CM program are stored in at least one disk device 3 in this embodiment. The entire area of the disk device 3 is divided into an area for recording a program and an area for storing various data such as incidental information of the program. In addition, the area for recording programs is
It is divided into an area for recording normal programs preferentially and an area for recording only CM programs. The CM program is first recorded in the area for recording only the CM program, and when it overflows, it is recorded in the empty area in the area for preferentially recording the normal program. The CM program recorded in this area may be deleted when the normal program is recorded.

When the same type of advertisement program exists, it is possible to insert and reproduce the advertisement program having the latest recording time together with the advertisement program to be reproduced. In this case, only the time required for the inserted advertising program,
It is necessary to delay the reproduction timing of the program to be continuously reproduced after the inserted advertising program. Further, in the case of inserting the advertisement program as described above while reproducing the program currently being broadcast, the program to be continuously reproduced after the inserted advertisement program is once recorded in the disc device or the like and is inserted. It is necessary to perform a process of playing the advertisement program, and after the playback of the inserted advertisement program ends, the subsequent program once recorded in the disc device or the like is shifted by the time required for the inserted advertisement program. is there.

[0052]

As described above, according to the present invention, it is possible to immediately retrieve and reproduce a CM program that has been broadcast in advance, when necessary. This is because it is possible to record the CM program in advance, accumulate the incidental information of the CM program, search this according to the desired search condition, and reproduce only the desired CM program. This enables the provision of new services that are attractive to viewers, broadcasters, and program providers.

Further, since it is automatically determined whether or not the received CM program should be recorded, it is possible to efficiently record the CM program which is highly necessary in the limited disk free space. This is because the viewer, the broadcaster, or the program provider specifies the condition of the CM program desired to be recorded, and only the CM program that matches this condition is recorded.
