Hereinafter, embodiments of the present invention will be described with reference to the drawings.

(Embodiment 1) FIG. 1 is a block diagram showing a basic configuration of a program recording / reproducing apparatus according to Embodiment 1 of the present invention. In FIG. 1, 1 is a signal input terminal for inputting a signal such as a broadcast signal, 3 is a signal receiving means having a function of extracting a desired signal from a received signal, and 4 is a signal extracted by the signal receiving means 3 as recording information. Recording means for recording, 5 is a recording medium medium, 6 is a recording medium reproducing means for reproducing recorded information, 8 is a related information medium medium having information related to a recorded received signal, and 7 is a related information medium medium 8 is reproduced. The related information reproducing means 2 is a reproduction signal output terminal for outputting a signal reproduced by the recording medium reproducing means 6.

A representative example of a signal input from the signal input terminal 1 is a broadcast signal. This includes broadcast signals such as radio signals, light and coaxial cable signals. It also includes signals transmitted on a one-to-one basis in the form of a network such as the Internet using a telephone line or a dedicated line. From the viewpoint of the program recording / reproducing apparatus, a signal that can be received as program information from a point where a program is transmitted is a reception signal. Desired signals are extracted from these received signals by the signal receiving means 3. Although it depends on the connection form of the signal line, it corresponds to a tuner device, a modem device, a decoding device for multiplexed received data, and the like. The data received via the signal receiving means 3 is signal-compressed in the recording means 4 and converted into a program signal recorded on the recording medium 5. Since the capacity that can be recorded in the recording media 5 is limited, long-time recording is realized by compressing the signal and reducing the amount of recorded information.

There are various types of recording media 5 such as magnetic recording media such as VTR video tapes and magneto-optical recording media. There are also tape-shaped media and disk-shaped media. Here, a DVD (Digital Ve
An explanation will be given using a disc (hereinafter abbreviated as DVD) called an “rsatile disc”. Among DVDs, there is a DVD-RAM as a recording medium that can be recorded and reproduced many times. This is a DVD-RO packaged media that is commercially available by compressing and recording video and audio information such as movie programs.
Unlike M (read-only DVD), it can be read and written many times like a video tape. Discs are different from tapes in that random access is easy to perform, cueing after retrieval can be performed quickly, and even in cases where recording is not performed in order, playback is performed with rearranged order while maintaining continuity during playback. Of course, a hard disk or the like often used in a personal computer or the like can be used as the recording medium 5. However, in the case of a recording medium medium such as a hard disk which cannot be attached or detached or requires much time for attachment / detachment, the recording capacity is limited. Therefore, in order to record a large number of programs, it is more convenient to use a removable recording medium because the recording capacity is not limited. Also, a recording media medium 5 (for example, CD-R or the like) to which writing is permitted only once can be used. The following describes an example of a removable DVD-RAM disc.

The recording medium 5 is inserted into the program recording / reproducing apparatus, and the recording means 4 records the program signal on the recording medium 5. At this time, information relating to the contents of the recorded program is added and recorded as program accompanying information. The program supplementary information includes time information such as a program start time and a recording period, and a broadcast station name (or a receiving channel name) as a recorded program name and essential information.
Then, time information is recorded together with the program signal in units of seconds or less. This is used when instructing reproduction of a specific portion in units of seconds during reproduction.

The recording means 4 adds time information when data of the received signal is compressed and recorded as a program signal. For example, time information such as a program start time and a program recording time, and periodic elapsed time information (eg, in seconds) from the program start time are recorded simultaneously with the program signal. The data compressed program signal is
It is separated by a specific data amount (abbreviated as a recording unit), and time information is inserted for the recording unit or for each of a plurality of recording units. This may be either an absolute time at the time of recording or a relative time from the start of recording. The purpose is to indicate time information at the time of reproduction and uniquely specify a corresponding recording unit to specify a reproduction position. For time adjustment between the broadcast time and the program recording / reproducing apparatus, a technique has been established in which a built-in clock of the program recording / reproducing apparatus is set separately by a time signal or the like.

Further, EPs such as program titles and program outlines
Information obtained by G or the like may be recorded simultaneously. When scene information, specific time information, or the like is included in a received signal such as a broadcast signal, the information is recorded together with the program signal as additional information of the program using the scene information and the specific time information. If a scene number is specified later, a specific portion of the program signal can be specified. Even if the program signal is recorded as a specific continuous file, special reproduction such as reproduction from the middle or reproduction of only a specific section can be performed by specifying time information and a scene number. Therefore, one program includes a recording start time, a recording time, a recorded program name (the above is essential), a broadcast subtitle name, a program production company name, a program outline, and the like (when the program can be received by EPG or the like).
In addition, a program signal, time information, and a scene number are recorded for each recording unit or a plurality of recording units. If necessary,
If the information can be added in the same manner as the time information for each recording unit, scalable program recording can be performed.

In order to record a received signal such as a video signal being broadcast on a DVD-RAM or the like, techniques such as signal compression and digital encoding are required. Therefore, when recording as a program signal, it is necessary to consider the processing time of the compression encoding of the received signal. If the reception time is used as the recording time as it is, there is a shift corresponding to the processing time of the compression encoding, and a desired video cannot be obtained during reproduction. When a broadcast signal or the like is an analog signal or a high-quality digital signal, the compression encoding is performed on a program of tens of minutes to several hours to perform DVD encoding.
-The recording capacity (for example, about several hundred megabytes to several gigabytes) that can be stored in a RAM or the like. Of course, in the case where the received signal is a signal that has been compression-encoded by a method that can be recorded on the recording medium medium 5 in advance,
Since there is no need to perform this compression encoding operation, there is no need to consider the processing time of this compression encoding. In the case of ordinary terrestrial broadcasting and satellite broadcasting programs, if a delay in communication time is taken into consideration, a deviation within seconds will inevitably occur, but this does not cause a serious problem unless a deviation of seconds or more occurs. Of course, as in the current NTSC system, 30 images are transmitted per second, and an accuracy of 1/30 second is required to specify each image. However, for applications that always play back a specific scene,
By configuring to reproduce from a place several seconds before, it is possible to cope with the situation without necessarily requiring the accuracy of 1/30 second. If the received signal itself from the broadcast signal contains time information from the start of the program, the received time information may be recorded together with the program signal. If time information recorded from a broadcast signal is read out, accurate time information can be obtained even if the time of the program recording / reproducing device is shifted, and is effective as time information to be recorded on the recording medium 5.

A case where recorded information including a program signal recorded on the recording medium 5 is reproduced will be described.

If there is no related information media medium 8 having related information relating to the recorded program accompanying information, or if there is no related information media medium 8 even if there is no related information of the program accompanying information of the recorded program, the conventional A specific program signal recorded with search information such as a program title is reproduced using the program supplementary information in the same manner as in the embodiment. Like the conventional example,
Since the information of the recording time and the channel name are recorded as the supplementary information of the program, if such information is displayed when the recording medium 5 is inserted, it is possible to select a title having no related information.

When the related information is present in the related information medium 8 and the reproduction is designated, the reproduction of the recorded program is started using the related information.

First, there are the following methods for searching for related information. Broadcast time information and program name (broadcast channel information and broadcast station name), subtitle name,
A program production company name or the like is used as a search key. If the broadcast received signal does not include any additional information such as a broadcast station name or a title name, the program recording / reproducing apparatus generates broadcast time information and broadcast channel information and uses the information as program accompanying information. Record. Alternatively, information such as a broadcast title acquired at the time of program recording reservation on a medium such as a CD-ROM or an EPG is recorded as program accompanying information. If such information is included in the broadcast received signal, the received information may be prioritized and set as the program accompanying information. And the program accompanying information,
It is recorded on the recording medium 5 together with the program signal. The recording medium 5 has a database configuration having a search key for designating a specific program from broadcast time information, an area number, a broadcast channel for each area, a broadcast program name, and the like. As for the area code, a specific area can be limited by inputting a postal code, a telephone number, or the like.

The program supplementary information is recorded on the recording medium 5 together with the program signal. At the time of reproduction, the recording medium reproducing means 6 reads out the program supplementary information together with the program signal,
The relevant information reproducing means 7 is notified. Related information reproducing means 7
Reads related information of a corresponding program using the program accompanying information as a search key.

An example of a data structure of program-related information in one application will be described below. FIG. 2 shows a data structure diagram of the program-related information. One piece of program-related information 71 includes title information 72, reproduction information of an original program signal (abbreviated as original program reproduction information) (81 and 82),
Related playback information (abbreviated as related playback information) (91 and 92), attached information 73, and an application program 74 using the above information are included. Title information 7
No. 2 is composed of a title name and information on the entire program. This may include application type and user limited information (unusable below a certain age, unusable if the specific password does not match, etc.), link information to another program, and the like. The original program reproduction information 81 includes time information such as a reproduction start time and a reproduction period of a specific portion, the number of times of reproduction, a reproduction speed, processing information of an original program signal (volume setting, enlargement / reduction of an image, change of color tone, etc. Instruction information for marking a portion, etc.) and other information. The related reproduction information 91 may be arbitrary for each application such as another voice or another image. Attached information 73
The information includes the history of additions and changes to the program-related information, the number of times the program-related information has been used, and the like (for illegal use of the program-related information, the use of the related information is prohibited, etc.). Further, a configuration in which a plurality of original program reproduction information and related reproduction information may exist in one program-related information 71 is adopted. There are several application options, and a plurality of pieces of original program playback information are required to play different playback locations depending on the selected content. Here, an example of the data structure of the program-related information 71 has been described, but the data structure may be different for each type of application. However,
Since information related to the reproduction of the program recorded on the recording medium 6 is important, only the original program reproduction information part needs to be common.

An example of the reproduction of a program signal will be specifically described using an example of an application emphasizing the content of the related information and the related information.

(1) Example of Application for Reproducing Only Appearance Scene of a Particular Performer In order to specify an appearance scene, time information (appearance start time and appearance period) from the program start time is required. In the program-related information 71, the appearance scene of the performer is stored as time information such as the reproduction start time and the reproduction period of the original program reproduction information 81. By using this time information, it is possible to specify the recording location of the program signal in which the appearance scene is limited, and it is possible to cope with an application in which the recording medium reproducing means 6 reproduces only a specific scene. When the application program 74 is executed and a specific performer is selected therein, if a performer different from the previously selected performer is selected, another corresponding original program reproduction information 82 is selected.
May be selected, the time information therein may be read, and the specified program signals may be sequentially reproduced. If necessary,
Automatically enlarge the screen in the scene where the specific person appears (using the processing information of the original program signal and expanding the appearance scene of the specific performer, such as audio fade-in and fade-out at the part where the specific performer utters) And marking the screen)
You can also. In addition, a choreographic reproduction application for a song program can repeatedly reproduce the same portion until the stop key is input (by specifying the number of times of reproduction of the original program reproduction information 81).

(2) An example of an information introduction application in which the broadcast program is a travel tour program and detailed information on the way is loaded First, the title is displayed by starting up the application program 74 from the relevant program-related information 71. Then, for example, the normal reproduction or the special reproduction is selected. In the case of normal reproduction, the original program signal is reproduced in order from the beginning at the normal reproduction speed. In the case of the special reproduction, first, the outline and the menu regarding the program will be described (display or voice guidance) using the audio and video information in the related reproduction information 91.
For example, a playback scene is selected by displaying a menu for selecting a specific scene. When a specific reproduction scene is selected by the user, the recorded program signal is reproduced using time information such as a reproduction start time and a reproduction period of the original program reproduction information 81 necessary for reproduction. Then, the reproduction is temporarily stopped in a scene that can be provided as the related information, and information such as time and fare information of a transportation system, a fare table of an inn or the like, a menu, and a room allocation are acquired from the related reproduction information 91 and displayed. Or, the scenery inside the train when playing the program,
A display indicating the presence of detailed information is displayed on the playback screen, etc., together with the playback of the accommodation scene, etc., and if a button or the like is pressed, the playback of the program signal is temporarily suspended and the related information is displayed. May be switched to. OSD (On Screen 3) is a method of superimposing another information image on the playback screen.
The original program signal can be reproduced without any processing by using the (n Display) function or the like. OSD is a commonly used technique for displaying a channel number or the like in reproduction of a TV or the like. Also, a configuration may be adopted in which the detailed information itself is displayed using a function of superimposing screens such as an OSD without temporarily suspending the reproduction of the program signal. The information handled as audio information and video information in the relevant reproduction information 91 in the relevant information is not limited to sampled audio, character information, and still images. Not only the video and audio signals generated by the same method as the signal compression used in the recording means 4 but also the video and audio compressed and coded by the signals that can be decoded by the recording media reproducing means 6. There may be.

An example of reproducing a scene of a specific performer and an example of providing detailed information of program contents have been described above.

Further, examples of secondary usage applications and related information using such program signals as materials are shown below. These are examples and not all described here. What is common is that a specific part of the original program signal is reproduced from the application side including the related information.

(3) Example of quiz program application The related information is assumed to be quiz questions and time information of a reproduced program indicating a quiz answer part. The application program 74 is executed, and a question is first set. The audio and video information indicating the problematic part of the related reproduction information 91 is reproduced. Then, the user is allowed to select an answer, and at the time of the answer, a reproduction location is specified and reproduced using time information such as a reproduction start time and a reproduction period in the specific original program reproduction information 81. If the playback of a part that is not related to the quiz answer is included during the playback of the program signal, the information such as the playback start time and the playback period, as well as the playback speed, etc., is used to automatically perform double-speed playback and skip the extraneous parts. You can also.

(4) Example of Scene Addition Application Not Broadcasted in Main Broadcast In this example, an application for inserting a scene that could not be broadcast due to broadcast time, playing back a scene from a different angle, and alternately playing is assumed. Will be explained. The program related information 71 stores related information such as video and audio information of the insertion or alternate scene and time information necessary for insertion. Then, specific scenes are sequentially reproduced using time information such as the reproduction start time and the reproduction period of the original program reproduction information 81. When the insertion time reaches the required time, another scene is reproduced using the video information and audio information not broadcast in the main broadcast in the related reproduction information 91, and when the insertion scene ends, the next original program reproduction information 82 It is sufficient to refer to the time information recorded in the file, specify the time portion during which the program is to be reproduced, and continue the reproduction. As for the alternate reproduction, a part to be reproduced may be specified each time the scene is switched. In this case, the application program 74 uses the original program playback information 81 and the related playback information 91 to specify a playback order so that playback can be performed without interruption and in order. Furthermore, it is assumed that the content of the related reproduction information 91 includes not only the cut video information and the like but also the time information of a specific scene. When dubbing a broadcast program or adding a subtitle language for a movie, etc., each change content information and time information, etc. are added. Plays back in synchronization with. However, since voice dubbing is difficult to synchronize with the screen when synchronized in units of seconds, units of seconds or less (such as a fraction of a second)
Synchronization is required. Therefore, it is preferable that the broadcast signal contains a scene number and time information in advance, and the broadcast signal is recorded in units of seconds or less in association with the program signal.

An application such as director's cut which was not broadcast in the main broadcast will be described. In this case, the program signal of the originally recorded program is realized by deleting a part of the program signal, rearranging the order of reproduction, or adding an appropriate scene. It is the same as the scene addition application). The application program 74 has information indicating a playback position and a playback order according to the director's cut playback content. Then, by specifying the cuts in the specified order, selecting the original program reproduction information 81 including the cut information, and reproducing the program signal of the recorded program from the reproduction time information and the information on the reproduction period, the broadcast program reproduction is performed. It is possible to realize the reproduction of the program in a different order.

(5) Example of Application to Game Application For example, a still image obtained by temporarily stopping a recorded program is used as a background of a shooting game or the like, or a game application using a reproduced image of a recorded program to introduce characters appearing in the game. Can also be applied. A specific scene is reproduced using time information such as a reproduction start time and a reproduction period in the original program reproduction information 81. The game is effective as an application for reproducing a recorded program using the related information as described above. Further, a still image of a specific scene or a specific scene is repeatedly reproduced by using various information in the original program reproduction information 81 in accordance with the progress of the game. Further, it is easy to superimpose a screen in which the reproduced program is reduced on the game screen, and to display the animation character of the popular program on a small screen or the like. In the introduction of the game character's deadly technique, a detailed description can be given while performing frame-by-frame playback of the program signal using the original program playback information 81.

If the related information medium 8 is a removable memory medium, it is not always necessary to mount it when recording a received signal. The program-related information 71 related to a recorded program can be taken out only when the recording medium medium 5 is reproduced. Since the related information is extracted from the program related information 71 at the time of reproduction, the related information media medium 8 suitable for the purpose of use can be selected from various related information media media issued at a later date of the broadcast. This eliminates the restriction that the related information must be created at the same time as the broadcast. (Of course, the provider of the related information must have obtained permission from the broadcast program creator or the like for secondary use of the broadcast program. Do). The program-related information 81 in the removable memory medium may be configured not to be easily copied. The program-related information 71 that has copy restriction information in addition to the usage count information in the attached information 73 and that is generated by a method other than the creation method determined by the related information provider must be configured so that normal operation is not performed. Can be. Therefore, it is possible to protect the copyright of the product of the related information provider. Further, one related information media medium 8 may include applications for a plurality of programs. Also one
It may include a plurality of applications that allow a plurality of ways to enjoy one program. What is necessary is that there is a recording capacity having a plurality of program related information. Removable memory media include:
A disk-shaped device such as a disk memory such as a CD-ROM or a DVD-ROM or a semiconductor memory having a semiconductor memory can be used.

If the related information medium 8 is a communication medium that can communicate with other communication devices, communication is not always necessary when recording a received signal, but is performed only when reproducing the received signal, thereby reducing communication costs. The latest related information can be obtained while reducing the amount. As one means, a homepage address for accessing the Internet or the like, search information, or the like is included in a broadcast signal of a specific program, and is recorded on the recording medium 5 together with the program signal as program supplementary information at the time of recording. Recording media 5
