Abstract

PURPOSE:To automatically execute video recording a broadcasting program even though the preferred broadcasting program is not being viewed and a program reservation is not being done. CONSTITUTION:A video signal discriminating circuit 20 supplies the discrimination data (o), which discriminates whether video signals (i) of a TV receiver 3 and video signals (d) of a tuner section 12 are matched or not, to a controlling circuit 14. The controlling circuit 14 discriminates the receiving channel of the TV receiver 3 by the discrimination data (o), produces program data (s), which a user prefers, by station selection data (p) and video recording data (q) and provides the program to a preferred program data memory 25. When the starting time of the time zone of the preferred program data (s) matches with the time indicated by a timing circuit 21 and the user is not viewing the preferred program and is not video recording, the controlling circuit 14 asks a video recording and reproducing circuit 16 to video record the previously mentioned broadcasting program.

FIG. 2 is a flow chart showing the operation of the automatic learning recording apparatus of FIG. 1, and the operation at the time of reproduction is omitted for simplification of description.

First, in step S1 shown in FIG.
The control circuit 14 determines whether it is in standby or power off, and when new recording is performed, that is,
If it is not in the standby state and the power switch is on, the determination is no, and in step S2, the recording data memory 2
3 is used to store new data, and then the control circuit 1
4 causes the recorded data memory 23 to read the recorded data q, and in step S3 it is determined whether the recorded data q is the desired program data.

If it is in standby or the power switch is off in step S1, it is determined in step S4 whether the video signal i is supplied to the second input terminal of the video signal discrimination circuit 20. If the video signal i is not supplied, the process returns to step S1 again. If the video signal i is supplied, in step S5, the control circuit 14 determines the video signal i and the video signal d based on the discrimination data o. Determines whether the two match. If the video signal i and the video signal d do not match in step S5, channel scanning is performed by switching channels in step S6. Control circuit 14
Repeats the operations of steps S5 to S6 until the discrimination data o indicates that the video signal i matches the video signal d of the tuner section 12. If the video signal i matches the video signal d, in step S7 The channel selection data k from the channel selection circuit 15 is determined to be the channel received by the television receiver 3, and the channel selection circuit 32 creates channel selection data k32 indicating the selected channel. From the data k32, channel selection data p indicating the channel of the program selected by the channel selection circuit 32 of the television receiver 3, the channel selection start time, and channel selection end time is created and stored in the channel selection data memory 22. .. After that, the control circuit 14 causes the tuning data p from the tuning data memory 22 to be read out, and step S3
At, it is determined whether the tuning data p is the desired program data.

In step S3, the duplication of the channel selection data p and the recording data q did not occur, that is, the user did not view the program of the same time period and the same channel, and recorded the program of the same time period and the same channel. If not, the determination is no and the process returns to step S1. On the other hand, tuning data p
Indicates that the same program has been viewed twice, or the recorded data q indicates that the same program has been recorded twice, the determination in step S3 is YES and step S8
In, the program data indicating that the same program was viewed twice,
Alternatively, the program data indicating that the same program has been recorded twice is stored in the favorite program data memory 25 as the user's favorite program data s. Next, in step S9, the control circuit 14 reads out the favorite program data s stored in the favorite program data memory 25, and the start time (recording start time or tuning start time) indicated by the favorite program data s.
And the time data m indicating the current time, the desired program data s and the current tuning data k of the tuning circuit 32 are selected.
A comparison calculation with 32 is performed, and the current recording data 1 of the recording / playback circuit 16 and the current tuning data k of the tuning circuit 15 are performed.
Is compared with the desired program data s, and in step S10, the channel indicated by the current tuning data k32 of the tuning circuit 32 is the favorite program data s.
Or the recorded data 1 indicates the recording state and the channel indicated by the channel selection data k matches the favorite program data s, that is, the user watches or records the favorite program. If yes, the decision is no,
Returning to step S9, if the user does not see the favorite program and is not recording, the determination is yes, and the control circuit 14 causes the recording / reproducing circuit 16 to record the favorite program in step S11. supply e,
The recording / playback circuit 16 is made to record a favorite program.

According to such an embodiment, when the user does not watch the favorite program and does not record the favorite program, the favorite program can be automatically recorded and the favorite program can be prevented from being overlooked. ..

In the above embodiment, the favorite program data memory 25 may be configured to be reset by the user's operation of the key input means 4 in response to the end of the continuous program or a change in the favorite.

On the other hand, in the above-described embodiment, as a method of judging a favorite program, whether the tuning data p from the tuning data memory 23 indicates that the program of the same day, the same time and the same channel is seen twice. , Or the recording data q of the recording data memory 23 indicates that the program of the same day, the same time and the same channel is recorded twice, the determination criterion is the television receiver and the magnetic recording. It is only necessary that at least one of the playback devices is within the range of the condition that reception is performed a predetermined number of times. That is, the tuner unit 12 is 2
The program may be determined to be a favorite program even when the broadcast program of the program of the same day, the same time, and the same channel is received only when the recording is not performed. In addition, a time limit is set for the determination of a favorite program, and it is determined as a favorite program when viewed or recorded twice, for example, in one month. All data may be cleared. Further, the program may not be judged as a favorite program by viewing and recording twice, but may be three times or four times, and the number of judgments may be limited to continuous counting. That is, for example, a program broadcasted at a predetermined time on a predetermined day every week is continuously (weekly) watched and recorded a predetermined number of times, it is determined as a favorite program, and the data is cleared when there is a gap for one week. May be set as follows.
