された場合に、番組予約装置によつて記録される
内容は所望の番組ではないという問題である。 In recent years, VTRs have become popular, and cases of recording desired programs from among broadcast programs are increasing.
In this case, some types of VTRs are equipped with a program reservation function, and the viewer enters the broadcasting station name, broadcast date, and start and end times of the program he or she wishes to record into the program reservation device in advance using information from newspapers, etc. It is now possible to automatically record desired programs. Troublesome problems may arise for viewers using such reservation devices. For example, when the broadcast time of a specific program (for example, a night game) is extended or shortened due to a night game broadcast, etc., and the broadcast time of the program is changed from the pre-scheduled time, it is recorded by the program reservation device. The problem is that the content being displayed is not the desired program.
現在の番組予約装置は、以上のような問題に対
しては何らの対策もほどこされていないので、
VTRが更に普及するにつれて大きな問題になる
と予想される。 Current program reservation devices do not have any countermeasures against the problems mentioned above.
This is expected to become a bigger problem as VTRs become more popular.
本発明は、そのような問題を解決する方法を提
供せんとするものである。 The present invention aims to provide a method for solving such problems.
以下、図面を参考にしながら本発明を詳細に説

The old data 7 consists of the same symbol content as in FIG. 1, and indicates the channel number, day of the week, start time, and end time on which a certain program was scheduled to be broadcast. New data 8 specifies the new broadcast time after the broadcast schedule has been changed, and consists of the same symbol content as in Figure 1, including the channel number, day of the week, and start date corresponding to the new broadcast time. Indicates time and end time. These old data and new data are superimposed on broadcast radio waves and broadcast by the start time of the old data. For example, it is broadcast by superimposing it on one horizontal scan during the vertical retrace period. The identification signal 6 is composed of a certain code,
Signals 7 and 8 are identification signals indicating that they are signals for changing program reservations.

コントロールされることになる。 FIG. 3 is a block diagram showing an embodiment of a changing device for changing a program reservation according to the present invention. In this embodiment, the program reservation change signal is the same as the program for which the program reservation has been changed. Superimposed only on broadcast television signals. Further, the receiving device 9 is installed in a VCR (not shown), and is energized while waiting for a reserved program (hereinafter referred to as an answering recording state). In other words, the timer circuit installed in the VTR (not shown) and the control circuit that controls answering machine recording are supplied with power directly from the main power supply of the VTR, and their operation is guaranteed as long as the main power supply is not cut off. There is. The receiving device 9 is controlled by the control circuit to be energized in the answering recording state, and its operation is guaranteed in the answering recording state. In this way, the receiving device 9
is receiving the broadcast television signal including the program reservation change signal while in the recording state.
In the figure, a receiving device 9 extracts a program reservation change signal from broadcast waves. The extracted program reservation change signal is supplied to the identification device 10, and it is confirmed that this signal is a program reservation change signal. When it is confirmed that it is a program reservation change signal, the old data is stored in the first storage device 11, and the new data is stored in the second storage device 11.
is written in the storage device 12 of. Third storage device 1
4, the channel number of the program that the viewer wants to record using the device that inputs the program reservation signal from the outside;
The day of the week, start time, and end time have already been set. That is, the third storage device 14 stores old data. The determination circuit 15 is connected to the first storage device 1
The contents of the first and third storage devices 14 are read and compared, and if the contents are the same, the contents of the second storage device 12 are transferred to the third storage device 14 through the control circuit 13.
Transfer to. In this way, the third storage device 14
Since a reservation signal corresponding to the new broadcast time is stored in , the program reservation device is controlled by this stored signal.
本発明により、希望する番組の記録が確実に行
