Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a video signal recording device, and more particularly to a video signal recording device having a function of obtaining and displaying an electronic program guide (EPG).

[0002]

2. Description of the Related Art In a video signal recording apparatus having a function of timer-reserving a television broadcast program, a user can obtain information such as a start time, a channel and an end time of a desired television broadcast program to be recorded. Book a timer,
When the reserved start time comes, the video signal of the television broadcast program of the reserved channel is automatically recorded until the reserved end time.

However, if the desired television broadcast program to be reserved and recorded is a sports relay program such as soccer or baseball, the broadcast time may be extended up to the maximum extension time. The broadcast end time may be exceeded. In addition, if the desired television broadcast program to be reserved and recorded is a broadcast program after a sports relay program with an extended match time, the reserved broadcast start time must be moved back by the time corresponding to the extended time. Becomes In such a case, the video signal of the desired television broadcast program cannot be accurately recorded on the recording medium from the program start time to the program end time without excess or deficiency.

Therefore, a program start / end time identification code,
The program-related information, which consists of the time difference data between the broadcast start time and the actual broadcast start time, receives the broadcast signal multiplexed with the program information, separates the program-related information, and analyzes it. By recording the video signal of the television broadcast program on the recording medium based on the above, even if the end time or start time of the desired broadcast program to be reserved-recorded is changed, the desired program information is started. 2. Description of the Related Art A video signal recording device that records on a recording medium from time to end time has been conventionally known (for example, Japanese Patent Laid-Open No. 10-1
1834).

In addition, in BS digital broadcasting and the like, individual identification information (ID) is added to each program for broadcasting, so that the end time and start time of the desired broadcast program to be reserved and recorded are changed. Even in such a case, by starting recording after detecting the ID, desired program information can be recorded on the recording medium from the program start time to the program end time.

[0006]

However, the conventional video signal recording device described in the above publication and the conventional video signal recording device for detecting the program ID of the BS digital broadcast and recording the video signal of the desired broadcast program. In this case, the program start identification code in the program-related information and the ID of the desired broadcast program are always waited in the recording standby state from the scheduled recording start time. During that time, the operation of the device is restricted and the recording is of course performed on the channel. There is a problem that it is not possible to even switch.

Although a method of changing the recording program by acquiring EPG data reflecting the program organization has been proposed, the handling during extension until the program organization is determined is unclear, and it is practical. Not. Further, conventionally, a dedicated service is required and it is not supported by the most needed terrestrial wave.

The present invention has been made in view of the above points,
Even if the end time or start time of the desired broadcast program to be reserved is changed without requiring a dedicated service, the video signal of the broadcast program is recorded almost exactly from the program start time to the end time. An object of the present invention is to provide a video signal recording device capable of recording on a medium.

[0009]

In order to achieve the above object, a first video signal recording apparatus of the present invention obtains a recording means for recording a video signal of a television broadcast program and an electronic program guide. The reserved recording setting means sets the reserved recording based on the acquisition / display means for displaying and the reserved recording setting means for setting the reserved recording of the broadcast program of the desired channel, and the electronic program guide acquired by the acquisition / display means. The program discriminating means for discriminating whether or not the broadcast program having a possibility of extension of the broadcast time or the program of the same channel after the program, and the broadcast program for which the reserved recording is set are determined by the program discriminating means. When it is determined that the program has the possibility of extending the broadcasting time or the program of the same channel after the program having the possibility of extending the broadcasting time, the broadcasting time may be extended from the electronic program guide. A maximum broadcast extension time acquisition means for acquiring the maximum broadcast extension time of the group, and a progress status acquisition means for acquiring the progress status of the program with the possibility of the extension of the broadcast time based on the live condition data acquired via the network, Based on the progress status acquired by the progress status acquisition means and the maximum broadcast delay time acquired by the maximum broadcast delay time acquisition means, the broadcast start time and the broadcast of the program of the same channel after the program with the possibility of extending the broadcast time A structure having an estimating means for estimating the end time and a control means for controlling the recording means so that the recording means records the video signal of the broadcast program for which reserved recording is set based on the time estimated by the estimating means. It is what

Therefore, it is possible to estimate the broadcast start time and the broadcast end time of the program of the same channel after the program with the possibility of extending the broadcast time based on the maximum broadcast extension time and the progress status.

In order to achieve the above object, the second video signal recording apparatus of the present invention obtains and displays the recording means for recording the video signal of the television broadcast program and the electronic program guide. Based on the acquisition / display means, the reserved recording setting means for setting the reserved recording of the broadcast program of the desired channel, and the electronic program guide acquired by the acquisition / display means, the maximum broadcast of the program with the possibility of extending the broadcast time Based on the broadcast maximum extension time acquisition means for acquiring the extension time and the electronic program guide acquired by the acquisition / display means, the broadcast program for which the reservation recording is set by the reservation recording setting means is A program discriminating means for discriminating whether or not a certain program or a program on the same channel after the program, and a broadcast program for which reserved recording is set have a possibility of extending the broadcast time by the program discriminating means. When it is determined that the program is a program that has the same channel or a program that has a possibility of extension, the progress status of the program with the possibility of extending the broadcast time is obtained based on the live data obtained via the network. On the basis of the progress status acquisition means, the progress status acquired by the progress status acquisition means, and the maximum broadcast delay time acquired by the maximum broadcast delay time acquisition means Recording means for estimating a broadcast start time and a broadcast end time of a program on the same channel, and a recording means for recording a video signal of a broadcast program for which reserved recording is set based on the time estimated by the estimation means And a control means for controlling the means.

In the present invention, unlike the first invention, first, the maximum broadcast time of a program having a possibility of extending the broadcast time is acquired based on the electronic program guide, and then the reserved recording is set. When it is determined that the broadcast program that was broadcast is a program that has the possibility of extending the broadcast time, or a program on the same channel after the program that has the possibility of extending the broadcast time, the broadcast program will be broadcast based on the live data acquired via the network. Although the progress status of a program with the possibility of time extension is acquired, the extension of the broadcast time is based on the maximum broadcast extension time and the progress status as in the first video signal recording device. It is possible to estimate the broadcast start time and broadcast end time of a program on the same channel after a possible program.

To achieve the above object, the third video signal recording apparatus of the present invention obtains and displays a recording means for recording a video signal of a television broadcast broadcast program and an electronic program guide. A broadcast program whose reserved recording is set by the reserved recording setting means based on the acquisition / display means, the reserved recording setting means for setting the reserved recording of the broadcast program of the desired channel, and the electronic program guide acquired by the acquisition / display means. But,
The program discriminating means for discriminating whether or not the program has the same channel after the program having the possibility of extending the broadcast time, and the broadcast program for which the reserved recording is set are judged by the program discriminating means for the possibility of extending the broadcast time. When it is determined that the program is a program of the same channel after a certain program, the maximum broadcast time extension acquisition means for acquiring the maximum broadcast time extension of the program with the possibility of extending the broadcast time from the electronic program guide, and the extension of the broadcast time. Control means for controlling the recording means so that the recording means records the video signal of the reserved recording program of the same channel after the program having the possibility of being longer by the broadcast maximum delay time acquired by the broadcast maximum delay time acquiring means. It is configured to have and.

According to the present invention, when it is determined that the broadcast program for which the reserved recording is set is the program of the same channel after the program having the possibility of extending the broadcast time, the broadcast time of the broadcast program acquired from the electronic program guide is displayed. Since it was recorded as long as the maximum extension time of the program with the possibility of extension,
Even if the broadcast time of a program that may be extended in time is extended, the video signal of the reserved broadcast program can be recorded to the end.

Further, in order to achieve the above object, in the fourth video signal recording apparatus of the present invention, the broadcast maximum extension time acquisition means of the third video signal recording apparatus is extended and moved back to the electronic program guide. If it is described, the difference between the normal end time and the maximum extension end time is obtained as the maximum broadcast delay time.If there is no maximum extension description in the electronic program guide The feature is that the time is acquired as the maximum delay time for broadcasting.

Further, in order to achieve the above object, the fifth video signal recording apparatus of the present invention is obtained by a receiving audio mode discriminating means for discriminating an audio mode of a received television broadcast program and an obtaining / displaying means. Audio mode comparison means for detecting the audio mode of the broadcast program for which the reserved recording is set by the reserved recording setting means based on the electronic program guide, and comparing the detected audio mode with the audio mode determined by the reception audio mode determination means. The control means according to the first aspect of the present invention is configured such that, in the vicinity of the start time of the broadcast program for which the reserved recording estimated by the estimating means is set, the audio mode determined by the reception audio mode determination means sets the reserved recording. The video signal of the broadcast program for which reserved recording is set since the comparison result matching the audio mode of the broadcast program is obtained by the audio mode comparison means, It is obtained by a structure for controlling the recording means so as to record the recording means.

According to the present invention, the broadcast start time of the program of the same channel after the program having the possibility of extension of the broadcast time is estimated based on the maximum extension time of the broadcast and the progress status, and the audio mode of the received broadcast program is set. However, since it is determined whether or not the scheduled recording detected from the electronic program guide matches the audio mode of the set broadcast program, it is possible to more accurately determine the broadcast start time.

Further, in order to achieve the above object, in the sixth video signal recording apparatus of the present invention, the broadcast program whose reserved recording is set by the reserved recording setting means has a possibility of extending the broadcast time. In addition, when the progress status acquired by the progress status acquisition means indicates that the game is canceled, the canceling means for canceling the recording by the recording means of the video signal of the broadcast program for which the reserved recording is set is further provided. It is what

In order to achieve the above object, in the seventh video signal recording apparatus of the present invention, the broadcast program for which the reserved recording is set by the reserved recording setting means has a possibility of extending the broadcast time. When the subsequent first broadcast program on the same channel and the second broadcast program on a different channel, the recording time zones up to the recording start time and the recording end time of the first broadcast program estimated by the estimating means are A time zone duplication determination unit that determines whether the second broadcast program overlaps with the original broadcast time zone, and when the time zone duplication unit determines that the time zones overlap, the first broadcast program and the second broadcast program The control means further has priority order notifying means for informing the user of which video signal of the broadcast program is to be preferentially recorded, and the control means is the video signal of the broadcast program selected based on the notification by the priority order notifying means. Or Each video signal of the first and second broadcast programs when the between bands do not overlap, is obtained by a structure for controlling the recording means so as to record by the recording means.

According to the present invention, when the broadcast program for which the reserved recording is set is the first broadcast program on the same channel and the second broadcast program on a different channel after the program having the possibility of extending the broadcast time. , When the broadcast time of a program whose broadcast time may be extended is extended, it is possible to record the video signal of one of the first and second broadcast programs whose time zones are overlapped, and When the bands become different, video signals of both the first and second broadcast programs can be recorded.

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings. FIG. 1 shows a block diagram of an embodiment of a video signal recording apparatus according to the present invention. In FIG. 1, a video signal recording / reproducing apparatus 10 includes a tuner 11 that receives a broadcast signal of a desired channel and obtains a received signal.
An encoder (ENC) 12 that encodes a received signal by an encoding method such as MPEG, a digital video recorder (DVR) 13 such as an HDD or a DVD-RW, and an MPE.
A decoder (DEC) 14 that decodes encoded data encoded by an encoding method such as G, and an EPG analyzer 15 that acquires and analyzes the EPG inserted in the vertical blanking interval (VBI) of the broadcast wave. An on-screen display (OSD) 16, an extension detector 17 connected to a network such as the Internet, and a central processing unit (CP).
U) 18 and is connected to a television monitor 20. The CPU 18 is the video signal recording / reproducing apparatus 1
Controls all parts of 0 in a centralized manner.

Next, the operation of the video signal recording / reproducing apparatus 10 configured as described above will be described. Introduction DV
The state of R13 will be described. During recording under the control of the CPU 18, the broadcast wave signal of the desired channel selected by the tuner 11 is selectively received by the tuner 11, converted into a reception signal in the base band and supplied to the encoder 12.
It is written into the DVR 13 after being encoded into a digital video signal of a broadcast program of a desired channel by a moving image coding method such as.

During reproduction, the DV is controlled under the control of the CPU 18.
The digital video signal read from R13 is returned to the video signal of the broadcast program of the desired channel by the decoder 14, and the operating state is added by the OSD 16, and then output to the television monitor 20 for viewing. Also, E
The PG analyzer 15 acquires the EPG data inserted in the VBI of the received broadcast wave from the tuner 11, analyzes the data content, and displays it in the display format on the OSD 16. The user selects an arbitrary broadcast program by operating the remote controller, and sets or cancels the recording reservation on the screen. It is assumed that the EPG data has information indicating the maximum extension time of the sports program. Currently, there is a service for transmitting EPG data by multiplexing it with VBI of broadcast waves.
For example, the data is transmitted every several hours a day, about five times, and once in about 10 minutes.

The extension time detector 17 is connected to the website via the Internet and detects the extension time of the broadcast program. The website accessed by the extension time detector 17 is a site that displays the scoreboard of a sports broadcast live. Currently, it is a service provided in major sports in Japan and the United States.

Next, as a general example of sports broadcasting, how extension of baseball broadcasting affects subsequent programs will be described. It is assumed that the program is organized as shown in FIG.
In the program shown in the figure, the display of "maximum extension 0924" during the professional baseball broadcast from 19:00 to 20:54 indicates that the professional baseball broadcast is extended to 9:24 pm at the maximum. That is, it means that the maximum extension time is 30 minutes. Therefore, if the professional baseball broadcast is extended to the maximum extension time, the CM of the same channel after that is extended.
The original 21:00 with the news from 20:54
The program of drama A that starts from 0 minutes starts at 21:30, which means that all the programs after drama A are broadcast with their start times being moved back by 30 minutes.

However, if the match ends before the maximum extension time, even if the original broadcast end time has passed, for example, if the match ends at 21:10, the digest of the match,
Adjust the time in hero interviews, etc., put the CM in between, and put it back in good 5 minutes increments 21
The program will be reorganized so that news starts from 19: 00 and drama A starts at 21: 25.

Based on the above, the operation of this embodiment will be described. First, the CPU 18 determines from the recording reservation list and the EPG whether there is a program affected by the extension of the sports broadcasting time. If there is a program that may be affected by the extension of the sports broadcast time, the extension determination described below is executed to record the video signal of the broadcast program. As an example, a case where the drama A in the program shown in FIG. 2 is reserved and recorded will be described.

First, when the CPU 18 judges from the recording reservation list and the EPG that the drama A to be reserved for recording is a program whose broadcast start time may be delayed due to the professional baseball broadcast at 19:00 broadcast start, Extension detector 17
Is connected to a predetermined Web site that distributes the live data of professional baseball via the Internet to start the operation, and the presence or absence of extension of the above-mentioned professional baseball broadcast is detected from the live data. The above-mentioned predetermined website is a site that is already known at present, in which the live scoreboard display of the sports broadcast is performed as described above. For example, the scoreboard display as shown in FIG. Deliver live data that can be displayed on.

The extension detector 17 is an EPG analyzer 15
The maximum extension time of the above-mentioned professional baseball broadcast has been acquired in advance from the EPG data from, and when the original broadcast end time of the above-mentioned professional baseball broadcast reaches 20:54, the live broadcast data from the website will be periodically updated. Get and start judging progress. That is, when the professional baseball broadcast end time of 20:54 when there is no extension of the broadcast is reached, live data is acquired from the above website, and the professional baseball game started to be broadcast from 19:00 ends. If so, the CPU 18 is notified of the detection result to that effect. This makes CP
U18 is D from 21:00 which is the original broadcast start time
The VR 13 starts recording the digital video signal of the drama A.

On the other hand, the extension detector 17 obtains the live data from the above website when the professional baseball broadcast ending time reaches 20:54, and the broadcast of the professional baseball game is back eight times. If not reached, W every 5 minutes thereafter
Re-access the eb site to obtain live data and judge the progress status one after another. Then, the extension detector 17 acquires live data every one minute from the time the broadcasted professional baseball game is broadcast 9 times or more until the end of the game is confirmed or the maximum extension time is reached.

The CPU 18 controls the recording start and the recording end of the DVR 13 based on the detection result of the match situation from the extension detector 17. That is, the CPU 18 presumes that the program is reorganized as described above depending on the situation such as when the maximum extension time is reached before the end of the match, or when the match is ended before the maximum extension time elapses. And later EP
It is reflected in G and the start and end times of the initially confirmed recording reserved program are changed.

For example, when the professional baseball broadcast is extended to the maximum extension time, the drama A program starts at 21:30, and the original broadcast end time has passed, but before the maximum extension time, for example, 21. If the match ends at 10: 00, the CPU 18 determines that the program of drama A will start at 21: 25, and the CPU 18 starts DV from the determined program start time.
Recording of the digital video signal from the concoder 12 by R13 is started.

Further, when the CPU 18 receives from the extension detector 17 a detection result indicating that the game is over before the maximum extension time, the CPU 18 considers the case where the offset for the time adjustment is deviated from the prediction, and the drama A is taken into consideration. It is possible to record more safely by taking measures such as recording the end time of 5 minutes longer. In addition, regarding the judgment of the progress of the game, if it is before the back of the eighth game, the live condition data is obtained every 5 minutes to make a judgment, and after the ninth game, the live data is checked every minute so that it is constantly monitored. It is not necessary to do so, and by making such an intelligent decision, there is an advantage that both the device as the client and the server as the information providing source are less burdened.

As described above, according to the present embodiment, the extension detector 17 determines the match status in almost real time based on the live data of the existing service acquired from the Web site, and extends the maximum extension before the end of the match. When it's time,
Depending on the situation, such as when the game ends before the maximum extension time, the start and end times of the first confirmed recording reservation program are changed to the estimated time for program reorganization, and the recording start and recording end times are changed. Since it is performed, there is no need to wait in the recording pause state from the broadcast start time of 21:00 of drama A to the postponed time of the actual broadcast start of drama A due to the extension of the professional baseball broadcast time as in the conventional case. Therefore, even in the conventional recording pause state, the operation of the device is not restricted in the present embodiment.

Even if the video signal recording / reproducing apparatus 10 is recording or reproducing operation after the original broadcast start time of the drama A, the number of minutes of reserved recording on the OSD 16, for example, before the postponed broadcast start time of the drama A. By displaying a message to start later, the reserved recording of drama A can be performed without any trouble.

Further, in the case of reserved recording of a digital broadcast program, since the ID is added to the program and the program is broadcast, as described above, the maximum extension time is reached before the end of the match, or the maximum extension time is reached. Depending on the situation such as when the game ends before the extension time, the start and end times of the first confirmed recording reservation program are changed to the estimated time of the program reorganization, and the changed estimated program start time Accurate reserved recording can be performed by starting a detection operation whether the ID of the reserved program is received from a time slightly earlier than that and starting recording from the time when the ID is detected.

In this embodiment, the extension time detector 17 is used.
Is connected to a predetermined Web site that distributes the professional baseball live data via the Internet to start the operation, and the presence or absence of extension of the professional baseball broadcast is detected from the live data. As described above, the above-mentioned predetermined website is a website that is already known at present, which is displaying the scoreboard of the sports broadcast live.

Acquisition of live data is not limited to such a method. When the device has a function of accepting a program reservation via a reservation mail from the outside, this reservation mail system may be diverted to acquire live data. The device confirms that the reservation mail has arrived and checks the mailbox of the mail server at intervals of 5 minutes. Therefore, as in the above-described embodiment, the live data may be acquired via email without directly connecting to the website.

That is, the Web site is made to provide the mail server with the live data, and this live data is transferred and sent as mail data to the mailbox of the contractor. When confirming the reservation mail, the device acquires this live data as a mail and the extension detector 17 detects the extension. With this configuration, access to the website is not concentrated and the live data is not dropped, and the server of the website is not overloaded.

Next, another embodiment of the present invention will be described. FIG. 4 shows a block diagram of another embodiment of the present invention. In the figure, the same components as those in FIG. 1 are designated by the same reference numerals, and the description thereof will be omitted. This embodiment has a configuration in which the voice recognition means of the program signal recording apparatus previously proposed by the present inventor in Japanese Patent Application No. 2001-227324 is added to the above embodiment. Here, the above-mentioned program signal recording device proposed by the present inventor is a program signal recording device for recording only a program main part in a program signal including a program main part and a commercial part, and is currently viewed from a received program signal. The audio mode of the current program is determined, and the determined audio mode is compared with the audio mode of the program detected from the separately acquired program. If the two match, the recording operation is performed, and if they do not match, the recording operation is stopped. It is a configuration that is adapted to do.

Therefore, in the video signal recording / reproducing apparatus 30 of the present embodiment shown in FIG. 4, the two-channel audio signal and its audio which are multiplexed in the TV audio multiplex broadcasting signal of the desired channel which is selectively received by the tuner 11. Based on the control channel signal among the control channel signals for mode identification, the audio mode discriminating unit 31 discriminates an audio mode in which the audio signal of two channels is stereo audio, monaural audio, or bilingual audio.

The audio mode comparison unit 32 acquires the first audio mode of the broadcast program of the desired channel to be reserved and recorded from the EPG data analyzed by the EPG analyzer 15, and further acquires the second audio mode of the sports broadcast program immediately before that. While acquiring the audio mode of, and comparing the acquired first and second audio modes with the third audio mode of the broadcast program being viewed from the audio mode determination unit 31, The comparison result is notified to the CPU 33. Here, the voice mode comparison unit 32 outputs the comparison result of the match when the first voice mode and the second voice mode are different and the third voice mode and the first voice mode match. .

The CPU 33, based on the live data of the existing service acquired by the extension detector 17 from the website, when the maximum extension time comes before the end of the match, or when the match ends before the maximum extension time, etc. Depending on the situation
The recording start operation of the DVR 13 is changed by changing the start time and the end time of the recording reservation program confirmed first to the time when the program reorganization is estimated, and further by correcting the time in consideration of the comparison result from the audio mode comparison unit 32. And control the recording end operation.

Therefore, according to the present embodiment, for example, when the reserved recording of the drama A in FIG. 2 is performed and the audio mode of the drama A and the audio mode of the news program are different, the CPU 33 estimates the program reorganization. Drama A obtained by
By starting the recording of the DVR 13 near the broadcast start time of the above and when the same audio mode as the audio mode of the drama A is detected, the recording from the beginning of the drama A can be performed more accurately than in the above embodiment. You can

The present invention is not limited to the above embodiment, and for example, the recording / reproducing means is a DVR13.
Of course, analog VCRs such as VHS (registered trademark) other than the above can be similarly applied. Further, the acquisition of EPG data is not limited to the VBI of the broadcast wave, and a method such as acquisition from the Internet or a data broadcast of digital broadcasting is also possible.

Further, in the above description of the embodiment, the recording reservation of the broadcast program after the sports broadcast has been described. However, if the recording reservation is made for the sports broadcast itself, based on the detection result of the extension detector 17, It is possible to automatically extend and record only the portion of the extended broadcast. Of course, the extension detector 17 may access the website one minute before the start of broadcasting, and cancel the recording program if the game is stopped.

Furthermore, when it is desired to record a video signal of a program broadcast when a sports program is stopped, it is possible to select to record only when it is determined to stop. This can be set by the user, of course
In the case of a device having a favorite recording function (agent function) such as a video recorder (PVR), it can be automatically executed.

Further, when the recording reservation of the back program (broadcast program of a channel different from the channel of the baseball broadcasting program) which originally did not overlap due to the extension of the baseball broadcasting overlaps with the recording reservation of the delayed program. For example, a message may be displayed on the OSD 16 during recording so that the user can select which recording reservation has priority. On the contrary, it is also possible to record the originally overlapped back program, which is no longer overlapped due to the extension of the baseball broadcast. For example, the original broadcast start time 2 of drama A
It is possible to record a back program, which has the same broadcast start time as 1:00 and has a broadcast time of 30 minutes, because the extension of the baseball broadcast for 30 minutes does not overlap with the drama A, so that it can be recorded.

The CPU 18 determines whether or not there is reserved recording of the back program, and if there is, the above-mentioned recording priority selection based on the detection result from the extension detector 17 and the start time and end time of the back program. Enables display and back program recording operation.

Further, in the above-described embodiment, when the reserved recording set channel is a sports program or a program after the sports program of the same channel, the maximum broadcast extension time of the sports program is acquired from the EPG data. However, the broadcast maximum extension time of all sports programs that may be extended may be acquired from the EPG data regardless of the presence or absence of reserved recording.

Furthermore, the present invention can be applied to both analog broadcasting and digital broadcasting if there is EPG data. Further, the maximum extension time of the sports broadcast may be acquired, and the reserved recording for the programs of the channel thereafter may be automatically recorded longer by the maximum extension time. In this case, the carry-down has two patterns A and B.

In pattern A, as in the example shown in the professional baseball program guide of the EPG data shown in FIG. 2, "(maximum extension 09
Up to 24), that is, when <maximum extension and delay> is described, the normal end time 2054 and the maximum extension end time 09
30 minutes, which is the difference from 24, is the maximum broadcast delay time. In the current program guide, 12 such as 0924 at maximum.
Although described in time notation, this is interpreted as 2124 with reference to the normal end time of the program.

In pattern B, when an important program such as a Japanese series or World Cup is simply described as "(subsequent program postponement)", that is, there is no description of maximum extension and only <postponement> When it is described, a predetermined specified time, for example, 1 hour is set as the maximum broadcast delay time.

By the way, the programs whose broadcasting time may be extended and the programs on the same channel after the programs are limited to the programs on the same day. Here, “within the day” is not the midnight when the date and time is changed, but the end of the final program over the next day. The confirmation may be the following a to c.

A. When <broadcast end information> is included in the electronic program guide, it is up to the program to which this broadcast end information is added. However, this broadcast end information is not added to the current EPG data.

B. If there is no broadcast end information, the program is up to the program until <Blank of program cancellation> is found.
If there is a time between the end time of a certain program and the start time of the next program, this blank is regarded as the program of the next day, and the program before the blank is set as the program within the current day.

C. If neither the broadcast end information nor the program blank of the broadcast stop is found, the program is up to the <program at a predetermined time>. For example, a program that starts after 4:30 and ends after 5:00 is regarded as the first program of the next day, and the program before this program is the last program of the day.

As described above, according to the present invention,
If it is determined that the broadcast program for which reserved recording is set is a program with a possibility of extension of the broadcast time or a program of the same channel after the program with a possibility of extension, the broadcast time acquired from the electronic program guide The maximum extension time of the program with the possibility of extension of the broadcast time and the progress of the program with the possibility of the extension of the broadcast time acquired based on the live data obtained through the network Since the broadcast start time and the broadcast end time of the program on the same channel after the possible program are estimated, the broadcast time may be delayed due to the extension of the broadcast time of the program, which may be extended. Even if a dedicated service is not provided, the broadcast start time of the program on the same channel after the program can be judged almost accurately by using the existing service. It can record the reservation recorded program in.

Further, according to the present invention, the broadcast start time of the program of the same channel after the program having the possibility of extension, which is delayed by the extension of the broadcast time of the program having the possibility of extension of the broadcast time, can be made substantially accurate. Because you can judge
It is possible to prevent the recording / reproducing device from being restrained until just before the start of recording of the program recorded by reservation recording, which allows the use of the device with a high degree of freedom.

Further, according to the present invention, when it is determined that the broadcast program for which the reserved recording is set is the program of the same channel after the program with the possibility of extending the broadcast time, it is acquired from the electronic program guide. By recording as long as the maximum extension time of the program that has the possibility of extending the broadcast time, the broadcast time of the program that has the possibility of extending the time can be extended even if the dedicated service is not provided. Also, the video signal of the reserved broadcast program can be recorded to the end.

Further, according to the present invention, the broadcast start time of the program of the same channel after the program of which the broadcast time may be extended is estimated based on the maximum broadcast extension time and the progress status, and the received broadcast is received. By determining whether or not the audio mode of the program matches the audio mode of the program main part of the broadcast program in which the reserved recording detected from the electronic program guide is set, a more accurate broadcast start time can be determined. Therefore, it is possible to record the broadcast program for which the reserved recording is set without excess or deficiency without performing unnecessary recording on the recording medium.

Further, according to the present invention, the broadcast program for which the reserved recording is set is the first broadcast program of the same channel after the program of which the broadcast time may be extended and the second broadcast program of the different channel. When the broadcast time of a program that has the possibility of extension of the broadcast time is extended,
It is possible to record the video signal of either one of the first and second broadcast programs whose time zones overlap, and when the time zones are different, the video signals of both the first and second broadcast programs can be recorded. Since the signal can be recorded, even if there is an extension of the broadcast time of a program that has the possibility of extending the broadcast time,
Flexible recording of video signals is possible.
