BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a recording / reproducing apparatus and, more particularly, to a recording / reproducing apparatus capable of reserving a plurality of programs and video-recording them.

[0002]

2. Description of the Related Art Conventionally, as a recording / reproducing apparatus of this type,
When setting a video recording reservation for a plurality of programs, the start and end times and channels for each program are input and set from a remote controller or an operation panel. Then, video recording is performed in order from the program with the earliest start time. Further, in recent years, the G code has been widely adopted, and the video recording of a program can be reserved by the G code.

The above-mentioned conventional recording / reproducing apparatus has the following problems. As a result of reservation setting of video recording of a plurality of programs, if there are video recording times that overlap, strictly, only the video recording of the earliest program is performed. For example, 7:00 on 2ch
~ A program broadcast at 8:00 and 7:
If a reservation is made for a B program that is broadcast from 30 to 8:30, all the A programs that are broadcast first will be video-recorded, while for the B program, only the 8:00 to 8:30 video will be recorded. Not recorded. Then, even if the user has a request to preferentially record the video of the B program, such a request is not reflected at all. Of course, 7:00 to 7:30 on 2ch
Scheduled video recording up to 7: 4ch
It is possible to make a reservation setting for video recording from 30 to 8:30, but the reservation setting operation becomes troublesome as the number of programs to be reserved becomes large, and the original convenience of the G code can be utilized. It's gone.

In this regard, in the method disclosed in Japanese Patent Laid-Open No. 9-163287, predetermined reservation setting is possible, and service outline information is detected from the received interactive service broadcast signal, and the service outline information and reservation setting are made. In a recording / reproducing apparatus that executes video recording when the contents match, it is possible to give priority to each reservation setting and realize video recording according to this priority. However, such an application is limited to interactive broadcasting, and cannot be applied to ordinary television broadcasting.

The present invention has been made in view of the above problems, and it is possible to set a reservation for video recording for a plurality of television broadcast programs, and the video recording is executed sequentially from the earliest program based on this reservation setting. In view of the above, an object of the present invention is to provide a recording / reproducing apparatus capable of executing video recording of programs with a desired priority even when video recording times of a plurality of programs overlap.

[0005]

In order to achieve the above object, the invention according to claim 1 is to receive a television broadcast signal according to a desired channel frequency, in which a VPS signal peculiar to a program is always included. Channel selection means having a second tuner, video recording means for performing video recording on a predetermined recording medium based on the television broadcast signal received by the first tuner, time measuring means for measuring the current time, and In order to video-record a plurality of programs whose broadcast times may be changed on the recording medium by the video recording means, program reservation information including start and end times and channels of each program is set in advance, and each program is recorded. About the reservation setting means for presetting priority information indicating the priority of video recording, and the above-mentioned reservation setting while monitoring the current time measured by the time measuring means. In order to cause the video recording means to perform video recording in order from the program with the earliest start time based on the program reservation information set in the column, it corresponds to each program reserved based on the program reservation information. By receiving the TV broadcast signal of the channel in sequence by the second tuner, the TV broadcast signal of the channel of the program having a higher priority than the program currently being video-recorded is received and the received TV broadcast signal is received. The presence or absence of the VPS signal of the program having the same priority is monitored, and when the VPS signal of the program having the same priority is detected, the television broadcast signal received by the first tuner is switched to the program having the same priority. And a video recording control means for executing video recording.

In the invention according to claim 1 configured as described above, for a plurality of programs whose broadcast times may be changed by the reservation setting means, a program reservation including the start and end times of the program and the channel. The information is preset and priority information indicating the priority of video recording for each program is preset. On the other hand, the time measuring means measures the current time, and the video recording control means executes video recording in order from the program at the earliest start time based on the time measuring result and the program reservation information set by the reservation setting means. Let Specifically, a television broadcasting signal having a channel frequency corresponding to each program is received by a channel selection means, and a predetermined recording medium is recorded by a video recording means based on the television broadcast signal received by the channel selection means. Let me record the video. It should be noted that in sports relay broadcasting, the broadcasting of programs may be extended and the broadcasting time of subsequent programs may be changed. In consideration of such a case, in recent years, by using a predetermined VPS signal, even if the broadcast time of the program is changed, the program can be completely video-recorded. This VPS signal is a program-specific signal included in the television broadcast signal, and even if the broadcast time of the program is changed, the corresponding VPS signal is not included in the television broadcast signal until the program starts. Instead, the VPS signal corresponding to the broadcast of the same program is included in the television broadcast signal.

According to the first aspect of the present invention, the channel selecting means includes the first and second tuners, and the video recording means always includes the VPS signal peculiar to the program and receives the VPS signal at the first tuner. Video recording is performed as described above based on the television broadcast signal. The video recording control means gives priority to the program currently being video-recorded by causing the second tuner to sequentially receive the television broadcast signal of the channel corresponding to each program reserved based on the program reservation information. The second tuner receives the television broadcast signal of the channel of the program with the higher priority, and the V of the program with the higher priority with this television broadcast signal is received.
The presence or absence of a PS signal is monitored, and when this VPS signal is detected, the television broadcast signal received by the first tuner is switched to a program of the same priority and video recording is executed. Therefore, when the video recording start time of a program with a higher priority is reached while the video recording of a certain program is being executed, the start time of the program with a higher priority is changed in sports relay broadcasting, etc. Even if so, the video recording is not started until the program with the same high priority actually starts, and the video recording is efficiently performed.

The start and end times of a plurality of programs to be video-recorded by the reservation setting means and the channels may be manually input by the user, or other cases may be assumed. As an example of the latter case, the invention according to claim 2 is the recording / reproducing apparatus according to claim 1, wherein the program reservation information is coded in accordance with a predetermined rule, and the reservation setting means,
The coded program reservation information is input to set the start and end times and channels of each program.

In the invention according to claim 2 configured as described above, the program reservation information including the start and end times of the program and the channel is coded in accordance with a predetermined rule, and the reservation setting means is The coded program reservation information is input to set the start and end times and the channel of the program to be video-recorded. A G code can be given as a specific application example. In the G code, the program reservation information as described above is coded into a numeric string of several digits according to a predetermined rule, and the numeric string is decoded and its contents are analyzed. In this case, although the input is easy, the start and end times of the program are fixed values that the user cannot operate, and it is easily understood that the present invention is suitable.

Needless to say, it is preferable that the reservation setting means sets the priority information for each program so that the user can easily understand it. As an example, the invention according to claim 3 In the recording / reproducing apparatus according to claim 1 or 2, the reservation setting means includes:
A menu screen is displayed on a predetermined display, and the priority information is set on this menu screen.

In the invention according to claim 3 configured as described above, in setting the above-mentioned priority information for each program, the reservation setting means displays a menu screen on a predetermined display device. The person sets the priority information on the menu screen. Of course, the display here may be a liquid crystal display panel or the like included in the recording / reproducing apparatus itself, and since such a recording / reproducing apparatus is usually connected to a television, a menu is provided on the television. A screen may be displayed.

As described above, in the present invention, it is sufficient that the program with the higher priority can be preferentially video-recorded. However, when the video recording of the program is finished, the program with the next highest priority is broadcast. It can be assumed that it is in the middle. Therefore, in the invention according to claim 4, in the recording / reproducing apparatus according to any one of claims 1 to 3, the video recording control means is one program based on the program reservation information and priority information. After video recording is performed, it is determined whether the program with the next highest priority is being broadcast, and if it is being broadcast, the same program is video-recorded.

In the invention according to claim 4 configured as described above, the video recording control means video-records a certain program based on the program reservation information and the priority information as described above, and the video recording is performed. Upon completion, it is determined whether the program with the next highest priority is being broadcast. Here, if it is determined that the program is being broadcast, the program is video-recorded.

For example, in the case of ch2, A from 7:00 to 9:00
Schedule the program and ch4 7: 30-8: 30 on the same day
It is assumed that the B program is set to be reserved and the priority of the B program is set to be high. In this case, first, the program A is recorded from 7:00 to 7:30 and then from 7:30 to 8:30.
Up to B program is video recorded. Then, when the video recording of the B program is completed, the A program is being continued, so that the A program is video recorded again from 8:30 to 9:00.

As described above, according to the present invention, it is possible to set a video recording reservation for a plurality of television broadcast programs, and in executing the video recording in order from the earliest program based on the reservation setting, Since the priority of video recording is set for a program, a recording / reproducing apparatus capable of executing video recording of a program with a desired priority even when video recording times of a plurality of programs overlap. be able to. Furthermore, while the video recording of a certain program is being performed, the VPS signal is monitored in the television broadcast signal of the channel of the program having a higher priority, and this VP is monitored.
When it is determined by the S signal that the program of the same priority has started, the program is switched to video recording of the program of the same priority. However, it is possible to efficiently record a high-priority program as a video.

According to the invention of claim 2, G
It is suitable for use when reservation can be set based on coded program reservation information such as a code.

Further, according to the invention of claim 3,
The priority can be set on a predetermined menu screen, which is easy for the user to understand.

Further, according to the invention of claim 4,
If the program with the next highest priority is being broadcast when the video recording of the one program is finished, the video recording for the same program is executed, so that the video recording of the program with the lowest priority is maximized. It can be performed.

BEST MODE FOR CARRYING OUT THE INVENTION <First Embodiment> A first embodiment of the present invention will be described below with reference to the drawings.
FIG. 1 is a block diagram showing a video deck to which the recording / reproducing apparatus according to the first embodiment of the present invention is applied. In this figure, this VCR is a tuner 10,
A signal processing system circuit including the video IC 20 and the RF converter 30 is provided, and the syscon 40 appropriately controls the operations of the signal processing system circuit and the video mechanism 50 to enable the video reproduction and the video recording. There is.

For example, when performing video reproduction,
With the video tape to be played back loaded, the remote control 6
Press the play button on the operation surface of 0. Then, the remote controller 60 transmits a predetermined infrared remote controller signal corresponding to the operation content. Then, this infrared remote control signal is received by an infrared remote control signal light receiving unit (not shown) on the video deck body side, and the syscon 40 detects the operation content. Then, the video IC 20 is notified that the video reproduction is to be executed, and the video mechanism 50 is caused to execute a predetermined reproduction process.

The video mechanism 50 includes a head system circuit 51 including a video head, an audio head, a full erase head for full width erasing, and the like, and a motor system circuit 52 including a reel motor, a capstan motor, and the like, which are also not shown. While driving the video tape, the signal is read from the tape recording surface and output to the video IC 20. Then, after predetermined signal processing is performed in the video IC 20, it is converted into an RF signal of VHF 1ch or 2ch by the RF converter 30 and output. Either one of the output channels of the RF converter 30 can be set by the user. In the present embodiment, since the television broadcast signal exists in the even channels, its output is set to 1ch.

On the other hand, when video recording is performed, the channel to be recorded and the standard / 3 times recording mode are selected on the operation surface of the remote controller 60 in the same manner.
Push down the video recording button. Then, similarly, the infrared remote control signal corresponding to this operation content is sent out,
It is detected by the system controller 40. And Syscon 40
Causes the video IC 20 to receive a television broadcast signal having a channel frequency corresponding to the detected operation content, notifies the video IC 20 that video recording is to be performed, and causes the video mechanism 50 to perform a predetermined video recording process. More specifically, the video IC 20 performs various kinds of signal processing on the output signal of the tuner 10 and outputs the output signal, and the video mechanism 50 drives the video tape to run according to the recording mode.
A signal is recorded on the tape recording surface based on the output signal of the video IC 20. From the above, in the present embodiment, the tuner 10 constitutes the channel selecting means, and the video IC 20
The system controller 40 and the video mechanism 50 constitute video recording means.

The VCR of this embodiment has a so-called timer reservation function, and program reservation information such as the channel of the program to be video-recorded, start time, end time, etc. can be individually input from the remote controller 60 or the like. Alternatively, by inputting the G code in the same manner, a desired program can be reserved and video-recorded. In this G code, the program reservation information as described above is coded into a number string of several digits according to a predetermined rule,
When the G code is actually input from the remote controller 60 or the like, the syscon 40 similarly detects it, and the internal timer / decoding circuit 41 decodes the input G code based on a preset area code, and The program reservation information is stored in a predetermined storage medium. If the above recording mode is set at this time, this recording mode is also stored in the same manner.

In addition to the above decoding process, the timer / decoding circuit 41 clocks the current time. Of course, in the present embodiment, the timer / decoding circuit 41 constitutes a clocking means. The system controller 40 monitors the start time of the program stored as the program reservation information and the timing result of the timer / decoding circuit 41, and when the start time comes, the above video recording is performed based on the program reservation information and the recording mode. Let it start. Then, at the end time of the program stored as the program reservation information, the video recording is ended. Of course, reservation setting by G code is possible for multiple programs,
In this case, video recording will be executed in order from the program having the earliest start time.

By the way, generally, in this type of VCR, when the video recording times of a plurality of programs overlap, the video recording of the preceding program is only executed. For example, as shown in FIG.
Program A broadcast at 9:30 and 7: 3 on the same day on 4ch
B program broadcasted from 0 to 8:30 and C program broadcasted on 6ch from 8:00 to 9:00 on the same day are respectively G
If you enter the code and set the reservation, the earliest start time A
Only the program is video recorded. Therefore, even if the user wants to preferentially record video in the order of B program, C program, and A program, such request is not reflected at all.

Of course, without using the G code, according to the predetermined operation, the A program is executed from 7:00 to 7:30.
B program from 7:30 to 8:30, 8:30 to 9: 0
If the C program up to 0 and the A program up to 9:00 to 9:30 are individually reserved, the video recording can be performed as desired by the user. However, such a reservation setting operation is troublesome, and it becomes impossible to utilize the original convenience of the G code.

Therefore, in the present embodiment, when the video recording of a plurality of programs is reserved and set, the priority order of video recording can be set for the plurality of programs. The priority order here is for preferentially video-recording a program having a high priority order, and when setting the priority order, a predetermined operation is executed on the operation surface of the remote controller 60. Then, in the same manner, the syscon 40 detects the operation content, and executes a predetermined priority order setting process according to the program shown in FIG.

Next, on the premise that the video recordings of the A program, the B program and the C program are reserved by the G code, the contents of the priority setting process will be described in detail. In FIG. 3, in step S110, a signal for displaying the menu screen shown in FIG. 4 is output, and is converted into a 1ch RF signal through the video IC 20 and the RF converter 30 and output. That is,
Referring to the figure, on the menu screen, program reservation information for each of the A program, B program and C program stored as described above, and a recording mode stored corresponding to each program, A setting column of priority order information indicating the priority order of video recording for each program is displayed. Here, the user uses the remote controller 60 to set the above priority order information in the same setting field. Then, step S1
At 20, the numerical value is displayed in the same setting field on the menu screen, and the set same priority information is stored in a predetermined storage medium. In this case, it is assumed that the priority order of each program is the order of B program, C program, and A program as described above, and the smaller the numerical value of the priority order information, the higher the priority order. There is.

When the setting of the priorities is completed, the remote controller 60 executes an operation to that effect. Then, it is detected in step S130, and next step S1 is detected.
At 40, the program reservation information of each program is internally changed as needed. The change of the program reservation information is generally performed as follows. First, referring to the program reservation information and the priority order information of each program stored in the storage medium, it is decided that the program having the highest priority order is video-recorded from the beginning to the end. That is, the program reservation information is not changed for such a program. After that, for the program with the next highest priority, the start time as the program reservation information will be set so that the video recording time can be maximized while avoiding overlapping with the video recording of the program for which the program reservation information was previously confirmed. Or change the end time appropriately and confirm. Thereafter, similarly, the program reservation information is appropriately changed and confirmed so that the video recording time can be maximized in the descending order of priority.

As described above, in this embodiment,
Since the priorities are given in the order of B program, C program, and A program, the program recording information is internally set as shown in FIG. 5, although it is a video recording reservation setting by G code externally. That is, the B program with the highest priority is
Video recording is fully reserved from 7:30 to 8:30,
For the C program with the next highest priority, video recording is reserved only between 8:30 and 9:00, which does not overlap with the video recording of the B program. Then, the A program having the lowest priority does not overlap with the video recording of the B program and the C program 7:
Video recordings between 00 and 7:30 and between 9:00 and 9:30 are reserved. Therefore, the user can execute the desired video recording simply by setting the priority information on the menu screen, and the troublesome reservation setting operation such as individually specifying the video recording time and making the reservation setting can be performed. It is unnecessary.

As described above, by inputting the G code or the like from the remote controller 60, the program reservation information is set in the syscon 40, and the menu screen is displayed by making full use of the video IC 20 and the RF converter 30.
Based on the input of the remote controller 60 on the menu screen, the system controller 40 sets the priority information of video recording for each program. In the present embodiment, these configurations serve as reservation setting means as a whole. Constitute. Further, the syscon 40 appropriately changes the program reservation information of each program in accordance with the priority order information of the video recording set as described above, so that the program of substantially higher priority is preferentially video-recorded. In this embodiment, the syscon 40 constitutes a video recording control means.

Next, the operation at the time of video recording using the timer reservation function of the video deck of the first embodiment configured as described above will be described with a specific example.
First, the user selects program A and program B shown in the time chart of FIG.
It is assumed that the G code is input from the remote controller 60 to set the reservation of video recording for each of the program and the C program. Then, the syscon 40 detects each input, decodes it based on a preset area code by an internal timer / decoding circuit 41, and predetermines program reservation information such as channel, start time and end time for each program. Stored in the storage medium. At this time, the standard / 3 times recording mode is also set, and the syscon 40 also stores this recording mode in the same manner.

Then, in order to set the priority order information of video recording of each program, a predetermined operation is executed by the remote controller 60. Then, the system controller 40 detects and the video IC 20
By using the RF converter 30 and the RF converter 30, the menu screen shown in FIG. 4 is displayed based on the program reservation information and the recording mode stored as described above (step S11).
0). In this input screen, when the user sets the priority order information of video recording for each program using the remote controller 60, the numerical value is displayed in the setting field on the menu screen, and the priority order information is stored in a predetermined storage medium. (Step S120). Then, when such setting is completed, the fact is operated by the remote controller 60 (step S130).

Next, the syscon 40 refers to the program reservation information and the priority order information of each program stored in the storage medium, and determines that the program with the highest priority order is video-recorded from the beginning to the end. . After that, for the program with the next highest priority, the start time as the program reservation information will be set so that the video recording time can be maximized while avoiding overlapping with the video recording of the program for which the program reservation information was previously confirmed. Or change the end time appropriately and confirm. Or later,
Similarly, the program reservation information is appropriately changed and confirmed so that the video recording time can be maximized in the descending order of priority (step S140).

Then, the B program with the highest priority is
Video recording is fully reserved from 7:30 to 8:30,
For the C program with the next highest priority, video recording is reserved only between 8:30 and 9:00, which does not overlap with the video recording of the B program. Then, the A program having the lowest priority does not overlap with the video recording of the B program and the C program 7:
Video recordings between 00 and 7:30 and between 9:00 and 9:30 are reserved. Then, the syscon 40 monitors the time measurement result of the current time by the internal timer / decoding circuit 41 and the changed program reservation information, and the tuner 10, the video IC 20 and the video IC 20 are reserved in order from the earliest reserved video recording. It is executed by appropriately controlling the operation of the video mechanism 50. Therefore, from 7: 00 to 7:30, A program,
B program from 7:30 to 8:30, 8:30 to 9:00
Up to C program, and from 9:00 to 9:30 are A programs in order.

In the present embodiment, the program reservation information of each program is internally changed beforehand according to the set priority order information, so that the programs according to the set priority order are given priority. I try to record video,
Of course, it is not limited to such a configuration. For example,
Even if the program reservation information is not changed internally, the program recording information of the earliest program is sequentially recorded, and the set program reservation information and priority information are appropriately referenced to give priority to the program currently being recorded. If it is determined that the program with the higher priority has started, the video recording of the program with the higher priority may be performed.

<Second Embodiment> A second embodiment of the present invention will be described below with reference to the drawings. Figure 6
The block diagram of the video deck concerning 2nd embodiment of this invention is shown. The video deck shown in the figure includes a signal processing system circuit including a tuner 210, a video IC 220, and an RF converter 230.
0 controls the operation of this signal processing system circuit and the video mechanism 250 including the head system circuit 251 and the motor system circuit 252 similar to those described above to perform video reproduction and video recording. Also, the remote controller 260
It is possible to set a program reservation information by inputting a G code or the like from, and to display a menu screen by executing a predetermined operation with the remote controller 260. It is possible to set such priority order information. In this respect, the VCR is similar to the first embodiment described above.

On the other hand, the difference from the first embodiment is that, in the first place, when video recording of a plurality of programs is reserved, even if the video recording of a plurality of programs overlaps, the syscon 240 Is that the program reservation information is not changed according to the priority order information. For example, using the G code in the same manner, A program broadcasted from 7:00 to 9:30 on 2ch, B program broadcasted from 7:30 to 8:30 on 4ch, and 8:00 from 6ch. It is assumed that the video recording of the C program broadcast at 9:00 is reserved and set, and then the priority order information is set in the order of the B program, the C program, and the A program. in this case,
The system controller 240 strictly stores the program reservation information of each program and the priority order information in a predetermined storage medium.

The next difference is that the tuner 270 for monitor different from the tuner 210 and the VPS slicer 2 are used.
And 80. The reception channel of the tuner 270 can be similarly controlled by the syscon 240, and the signal output from the tuner 270 is input to the video IC 220 and subjected to various signal processing,
It is input to the VPS slicer 280, and a predetermined VPS signal is extracted by this VPS slicer 280. Here, the VPS signal is a program-specific signal that is superimposed on a television broadcast signal, and is always included in the television broadcast signal during the broadcast of the program. Therefore, for example, as shown in FIG. 7, assuming that the B program is delayed by 30 minutes due to the extension of sports broadcast, the VPS signal in the TV broadcast signal of the B program is between 8:00 and 9:00. You will only be able to extract.

The syscon 240 executes the video reservation recording process according to the flowchart shown in FIG. 8 while utilizing the VPS signal. In the figure, step S31
At 0, the tuner 270 sequentially receives the television broadcast signals of the channels corresponding to the reserved programs, based on the program reservation information set as described above. Then, when the program reserved by the television broadcasting signal of each channel is being broadcast, the VP
The S slicer 280 should output the VPS signal for the same program. Therefore, in the next step S320, the presence or absence of the VPS signal of the reserved program is detected, and if such a VPS signal exists, the VPS signals of the plurality of programs reserved in the next step S330 are detected. To detect whether or not exists.

In step S330, if there are VPS signals for a plurality of reserved programs, the priority of video recording is high in accordance with the priority information set in step S340 as described above. Select a program to run a video recording. On the other hand, step S
If there is no VPS signal for a plurality of programs in 330, video recording is performed for the program in which the VPS signal exists among the reserved programs in step S350. After that, returning to step S310, the same processing is repeated, and when it is detected that the VPS signal of the program set to be reserved is not present in step S320, the video recording is stopped in step S360.

Therefore, when the broadcast time of the program B is delayed by 30 minutes as shown in FIG. 7, 7:00 to 8: 0
Up to 0, only the VPS signal of the A program can be extracted, and the video recording of the A program is executed during this period. And 8:
At 00, the VPS signals of the A program, B program and C program can be extracted, but since the B program has the highest priority, the B program is video-recorded. After that, 9: 0
When it becomes 0, the VPS signals of the B program and the C program are interrupted and only the VPS signal of the A program can be extracted again.
Video recording of program A is resumed. Further, at 9:30, the VPS signal of the A program is also interrupted, so that the video recording of the A program is finished.

Therefore, the actual video recording becomes as shown in the time chart of FIG. 9, and C having the second highest priority is recorded.
Although the program will not be video-recorded at all, it can be said that the B-program with the highest priority is preferable because it is surely video-recorded from the start to the end even if the broadcast time is delayed. It goes without saying that even if the broadcast of the B program with the highest priority is extended, the B program is surely video-recorded.

Next, the operation at the time of video recording using the timer reservation function of the video deck of the second embodiment configured as described above will be described with a specific example.
First, the user selects program A and program B shown in the time chart of FIG.
It is assumed that the G code is input from the remote controller 260 to set the reservation of video recording for each of the program and the C program. Then, the syscon 240 stores the program reservation information for each program in a predetermined storage medium. At this time, the standard / 3 times recording mode is also set, and the syscon 240 similarly stores this recording mode. Further, when a predetermined operation is performed with the remote controller 260, a menu screen is displayed, and the user sets priority order information for video recording of each program on this menu screen. Then, the syscon 240 similarly stores the priority order information.

Thereafter, the syscon 240 causes the tuner 270 to sequentially receive the television broadcast signals of the channels corresponding to the reserved A program, B program, and C program, and the video IC 220 and the VPS slicer 280 are received.
The presence / absence of a VPS signal for each program is detected via, and the presence / absence of a VPS signal for a plurality of programs is detected. (Steps S310 to S330). Here, referring to FIG. 2, since only the program A starts to be broadcast at 7:00, the system controller 240 operates as a tuner 21.
At 0, the television broadcast signal of the A program is received, and thereby the video recording of the A program is executed (step S35).
0).

At 7:30, the broadcast of the B program should originally start, but the broadcast time of the B program is delayed by 30 minutes as shown in FIG. , At this point, the video recording of program A is still continued. After that, at 8:00, broadcasting of the B program and the C program is started, so that the syscon 240 detects the VPS signal for all of the A program, the B program, and the C program. Then, the syscon 240 selects the B program having the highest priority among the programs based on the stored priority information and executes the video recording (step S34).
0).

At 9:00, the broadcasting of the B program and the C program ends and the VPS signal of the program is interrupted, so that the syscon 240 detects only the VPS signal of the A program. Then, the syscon 240 restarts the video recording of the program A (steps S330 and S350). After that, at 9:30, A
Since the broadcast of the program is finished and the VPS signals of all the programs are interrupted, the Syscon 240 cannot detect the VPS signal,
Video recording for program A also stops (step S3).
20, 360).

As described above, the program reservation information such as the G code is set from the remote controller 60 to reserve a plurality of programs for video recording, and the priority information indicating the priority of video recording for the reserved programs is set. And the tuner 10, the video IC 20 and the video mechanism 5 on the system controller 40.
When the video is recorded in order from the earliest program based on the set program reservation information while appropriately controlling the operation such as 0, the program with higher priority is preferentially video recorded based on the set priority information. By doing so, it is possible to provide a recording / reproducing apparatus capable of executing video recording of programs with a desired priority even when video recording of a plurality of programs overlaps.
