Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a program signal recording apparatus for recording a program partially including a commercial on a recording medium, and a program signal recording / reproducing apparatus for reproducing such a program recorded on the recording medium.

[0002]

2. Description of the Related Art In the field of a video tape recorder (hereinafter, referred to as a VTR) for recording and reproducing a program signal on a magnetic tape, a commercial portion included in a program is detected, and only a main program portion excluding the commercial portion is detected. Is recorded on a magnetic tape, or the entire program including a commercial portion is recorded on a magnetic tape, and a commercial portion is detected during reproduction, and only the commercial portion is fast forward reproduced.

Recently, a private video recorder (hereinafter, referred to as a PVR) for recording and reproducing program signals using a hard disk has been developed and commercialized. A process of skipping the commercial part and reproducing only the main part of the program at times can be performed relatively easily.

As described above, in the field of VTR or PVR, recording or reproduction of a commercial portion is not performed,
Techniques for recording or reproducing only the main part of the program are being established, but such techniques have become a major problem for commercial providers.

[0005] In the future, instead of watching the broadcasted program in real time, a viewing method in which the program is temporarily stored in a home server or the like and time-shifted and played back according to the user's convenience becomes mainstream. However, when such a viewing method is adopted, there is a large problem that the commercial portion is not reproduced.

[0006] Under such circumstances, with the bidirectionality of information transmission by digitalization of television broadcasting, a discount system of viewing fee according to the viewing situation of a commercial part is being studied. Is introduced, it is considered that the entire program including the commercial part is recorded on the recording medium, and the commercial part is reproduced based on the user's intention.

[0007]

However, commercials often have timeliness in which the value of watching is lost unless viewers watch the video within a certain period, and it is timely. Watching a commercial that did not make sense. For example, even if a commercial related to a new product or a commercial related to a bargain sale is recorded by a recording device, if it is reproduced one year later, there is almost no advertising effect.

[0008] In addition, commercials are often replaced with new ones at predetermined time intervals so as to always provide a fresh image to the advertising object. However, if the recorded old version of the commercial continues to be reproduced, the old image is added to the advertising object. The advertiser's advertising effect diminishes.

[0009] In addition, commercials are often broadcasted over and over again, and when many programs are recorded, the same commercial is recorded many times in accordance with this. If the recording is repeated many times, the recording capacity of the recording medium is wasted.

[0010] As described above, in a recording / reproducing apparatus for recording and reproducing a commercial, how to record and manage the commercial on a recording medium while making use of the effect of the commercial will be a major issue in the future. I was

[0016]

FIG. 1 is a block diagram for explaining a program signal recording apparatus and a program signal recording / reproducing apparatus according to an embodiment of the present invention, in which an incoming program signal is recorded in a digital signal form. . Note that this program signal is transmitted together with the additional information, and the additional information includes various information as described below.

[0017] Here, the transmitted program can be roughly classified into a program title portion, a program main body portion, and a commercial portion. As additional information, a title name and a title version are added in the program title portion. In the main part, performers and program genres are added, and in the commercial part, commercial names, company names, expiration dates, and commercial versions are added.

In FIG. 1, reference numeral 1 denotes an additional information acquiring unit for acquiring additional information added to an incoming program signal, and 2 denotes a recording signal processing to be described later, which is input with the additional information acquired by the additional information acquiring unit 1. , A microcomputer that controls the operation of the recording, reproduction control unit, and the reproduction signal processing unit.

Reference numeral 3 denotes a recording signal processing unit which receives a program signal, performs a modulation process or the like necessary for recording on the program signal under the control of the microcomputer 2, and outputs the recording signal. A recording medium 5 on which a program signal to be output is recorded is a recording / reproduction control unit 5 for controlling a recording operation when recording the program signal on the recording medium 4 and a reproduction operation when reproducing the program signal from the recording medium 4. A reproduction signal processing unit outputs a program signal reproduced from the recording medium 4 under the control of the microcomputer 2 after performing demodulation processing and the like necessary for reproduction. Note that a large-capacity hard disk or the like is used as the recording medium 4.

The operation of the program signal recording device and the program signal recording / reproducing device configured as described above will be described with reference to FIGS. 1 and 2. When the recording of a program is started, the additional information obtaining unit 1 obtains additional information from an incoming program signal and outputs this additional information to the microcomputer 2. Then, based on the additional information from the additional information acquisition unit 1, the microcomputer 2 determines whether the incoming program signal is a program title portion, a main program portion, or a commercial portion.

Here, the microcomputer 2 controls the operation of the recording signal processing unit 3 and controls the recording / reproduction control unit 5,
Of the program signal output by the recording signal processing unit 3, the program title portion, the main program portion, and the commercial portion are respectively recorded in separate recording areas on the recording medium 4, and the additional information is also recorded in another recording area. Each part is controlled so as to be performed.

That is, when it is determined that the incoming program signal is a program title portion based on the additional information from the additional information acquisition section 1, this program signal is recorded in the recording area for the program title. If the recording and reproduction control unit 5 is determined to be the main program part, the recording and reproduction control unit 5 is controlled so that this program signal is recorded in the recording area for the main program, and the commercial part is controlled. If it is determined that the program signal exists, the recording / reproduction control unit 5 is controlled so that the program signal is recorded in a commercial recording area.

Further, the additional information transmitted together with the program signal is:
The microcomputer 2 controls the recording / reproduction control unit 5 so that all of the information is recorded as file management information in the recording area for file management information. For each part and file management information forming a program signal, a recording area may be individually provided as described above, and each may be recorded in the recording area.
Each part and file management information may be recorded without providing such a dedicated recording area.

FIG. 2 is a diagram schematically showing a state of a program A recorded on the recording medium 4, in which a program title portion, a main program portion, and a commercial portion are recorded in separate recording areas. ing. The program signal is recorded in file units as shown in the figure, and each of a program title portion, a main program portion, a commercial CM1, a main program portion, a commercial CM2, and a main program portion is formed in one file. Information indicating the recording position of each file is recorded in the file management information recording area as a part of the file management information.

The arrows shown in the figure indicate links, for example, indicating that the last part of the program title and the first part of the main program are continuous. This link information is also recorded in the file management information recording area as a part of the file management information.

When recording the program A, for example, with the program A already recorded on the recording medium 4, first, the file management information on the recording medium 4 is read out, and the Not stored in the memory area. Then, the microcomputer 2 compares the additional information of the incoming program signal with the additional information stored as file management information, so that the microcomputer 2 does not record the same program signal.
Control.

That is, the additional information of the incoming program B is compared with the additional information in the memory, and if the program title and the title version match, the same program title is already recorded on the recording medium 4. The program signal is not recorded during the period when the program title is added. Also, if the commercial name, company name, expiration date, and commercial version all match,
Assuming that the same commercial is already recorded on the recording medium 4, the program signal for that period is not recorded.

[0028] Therefore, the first drama of the drama that was broadcast program A yesterday
If the program B is the second broadcast that is a continuation of the drama broadcast yesterday in the first broadcast, the program title and title version are the same, so that the program of program B broadcast today is The title part is not recorded. Also, when the same commercial is broadcast, this commercial part is not recorded.

Then, along with this, as file management information,
A program main part of the program B and a program title part shown in FIG. 2,
Since the link information to the commercial parts (CM1 and CM2) is newly generated, when the program B is reproduced, the program title part and the commercial part are reproduced in addition to the main part of the program. Since the link information of the program A is not deleted, after recording the program B, the program A
Can be played back, the program title portion and the commercial portion can be played back.

[0030] In the case of a serial drama, the program title part may be replaced with a new one from the broadcast partway through. In such a case, the program title in the broadcast program signal matches the program title in the memory, but the title version does not match, so that the program signal in the program title portion is stored as a new file in the program title on the recording medium 4. Is recorded in the recording area for use.

[0031] Even a commercial related to the same product may be replaced with a new commercial from a certain time. In such a case, the commercial name and the company name match between the additional information in the broadcasted program signal and the additional information in the memory, but the commercial version does not match, so that the commercial program signal is added to a new file. Is recorded in a commercial recording area on the recording medium 4.

At this time, the old version commercial is overwritten and erased by the new version commercial. For example, if the viewer likes the old version commercial and wants to keep the old version commercial as it is. If there is, you may be able to leave this.

[0033] Also, when the commercial name, company name, and commercial version match between the additional information in the broadcasted program signal and the additional information in the memory, and only the expiration date does not match, similarly, The program signal is recorded in a commercial recording area on the recording medium 4. In this case, the commercial recorded on the recording medium 4 remains.

As described above, in the program signal recording apparatus according to the present invention, when the same program title portion or commercial has already been recorded on the recording medium 4, this program title portion or commercial is not redundantly recorded. Therefore, the recording capacity of the recording medium 4 is not wasted.

Each time the microcomputer 2 reads out the file management information from the recording medium 4, the microcomputer 2 checks whether there is any commercial whose expiration date has passed. In other words, each commercial has a date of expiration date, but a commercial whose expiration date has passed can be deleted from the recording medium 4 or can be overwritten.

For example, the commercial (C) of the program A shown in FIG.
M1 and CM2), and if the expiration date has passed, CM1 and CM2 are deleted first, and the link information of the program A is changed so that the main part of the program A is continuously reproduced. Updated and recorded as file management information.

That is, a commercial that has passed its expiration date and is considered to be unable to obtain the original advertising effect is automatically deleted from the recording medium 4, so that it is not necessary to see useless commercials. Not only
The recording capacity of the recording medium 4 is not wasted.

Next, the deletion of a commercial according to the number of times of reproduction from the recording medium 4 will be described. When reproducing the program A from the recording medium 4, the microcomputer 2 controls the recording / reproduction control unit 5, and the file management information on the recording medium 4 is read. The file management information is stored in the microcomputer 2
The program A is stored in a memory area in the storage medium and is reproduced from the recording medium 4 based on the file management information. That is, the recording / reproduction control unit 5 is controlled based on the information on the recording position of the file of the program A included in the file management information and the link information, and the program title portion, the main program portion, and the commercial portion are respectively reproduced.

When the commercial portion (CM1, CM2) is reproduced during the reproduction of the program A, the number of reproductions of the commercial is counted, and when the same commercial is reproduced a predetermined number of times, the number of reproductions is increased. Commercials can be deleted or overwritten.

[0040] Here, if the commercial part is a commercial to be reproduced for a plurality of programs,
Instead of allowing the commercial to be deleted or overwritten, the link information is updated so that the commercial is not reproduced.

For example, the commercial portion (CM) shown in FIG.
1, CM2) is a commercial broadcasted by both the program A and the program B, the commercial portion cannot be deleted or overwritten only by playing the program A a predetermined number of times. Only the link information is updated.

That is, when the program B is reproduced, the commercial portions (CM1, CM2) are reproduced.
Is reproduced a predetermined number of times, the commercial portions (CM1, CM2) can be deleted or overwritten for the first time.

In the above description, as shown in FIG. 2, an example is shown in which the program title portion, the main program portion, and CM1 and CM2 are all recorded on the recording medium 4 as separate files. However, the present invention is not limited to this. If it is necessary to record the entire program A in one file and delete the commercial part and the like, a new file excluding the commercial part may be generated at that time. If it is necessary to record the entire program A in one file and delete the commercial part and the like, the entire program A is divided into several files at that point, and the parts other than the commercial part are linked information. You may connect.

In the above description, the commercial name, the company name, the expiration date, and the commercial version information are added as the additional information of the commercial part. When it is difficult to determine whether or not the genre of the product to be advertised is added as additional information, the information may be used.

[0045]

According to the first or fifth aspect of the present invention, a commercial or a program title identical to a commercial or a program title already recorded on a recording medium is not recorded in duplicate. It does not waste the recording capacity of the recording medium even in the case where the same commercial or program title is inserted every time a drama or the like that is broadcast continuously is repeatedly recorded in the drama. It works.

According to the second aspect of the present invention, the program signal on the recording medium can be erased or overwritten based on the information on the expiration date. In addition to not only watching old commercials having no advertising effect, it is also possible to secure free space on the recording medium.

According to the third aspect of the present invention, even if the commercial recorded on the recording medium and the incoming commercial are the same commercial, if the commercial version is newer, the new commercial is replaced by the old commercial. Since the commercial is overwritten and erased, it is possible to prevent an old image from colliding with the advertisement target, and it is possible to enhance the advertisement effect.

According to the fourth aspect of the present invention, a commercial that has been viewed a predetermined number of times is deleted from the recording medium or can be overwritten. , The free space on the recording medium can be secured.
