The broadcast control device 2 controls the operation of the broadcast equipment device 1 so as to send out broadcast programs according to a predetermined schedule, and also sends out reception control information. It is configured. For example, in the case of the common channel system described later, the reception control information includes a program identification code unique to each program that is necessarily set for each program to be broadcast, and the start of broadcasting of the program, as shown in Figure 3. It consists of a group of information that is a combination of control codes that indicate preparation, broadcast start, and broadcast end categories, and broadcast frequency information that indicates the frequency (channel) on which the program is broadcast. The reception control information is sequentially sent out at appropriate times before the broadcast program is sent out on a dedicated frequency for broadcasting.

The multiplexer 3 is only for multiplexing broadcast programs and reception control information. The reception control information includes, for example, an intra-channel multiplexing method that modulates and broadcasts the subcarrier of the broadcast signal of a program, or reception control information related to multiple broadcast programs that includes auxiliary information for identifying the frequency at which each broadcast is performed. It is multiplexed and sent using a common channel method in which the information is added and multiplexed, and reception control information is broadcast on a predetermined frequency. In addition, in television broadcasting, it is also possible to use a retrace insertion method in which a retrace line is inserted in a scanning retrace period.

In this embodiment, a common channel method is used, but in the case of an intra-channel multiplexing method or a retrace insertion method, it can be supported by changing the configuration of the multiplexer 3 and the reception fee information receiving section 7, which will be described later. It is.

The reception station 11B is provided with a reception control device 5 and a reception device 6, respectively.

The reception control device 5 detects the broadcast of the reserved broadcast program when the receiver specifies a specific broadcast program and makes a reservation for reception.
The receiving device 6 is made to automatically receive the broadcast program. For this purpose, the reception control device 5 includes a reception control information receiving section 7, an input section 8, a storage section 9, and a control section 10.

The reception control information receiving section 7 receives a specific frequency on which reception control information is broadcast. The input section 8 is for the receiver to input reservation information, and allows the receiver to specify the program identification code of the broadcast program to be received and whether recording is necessary using a keyboard or the like. The storage section 9 stores and holds the reservation information inputted from the entrance section 8. The control unit 10 analyzes the reception control information and the reservation information and controls the reception device 6.

FIG. 4 shows an example of the storage format of reservation information etc. registered in the storage section 9. The receiver can register the reservation information in the storage section 9 by operating the input section 8 and manually inputting the program identification code of the broadcast program he/she wishes to receive and whether or not the program needs to be recorded. Furthermore, it is possible to reserve multiple programs by repeating the operation. The reservation information consists of the program identification code of the program for which reception is reserved, and recording instruction information that stores the recording instruction when the receiver instructs to record the program. A diagram is provided in the storage section 9. Also, a reception preparation column is also set in the storage section 9, and this reception preparation column is a work area used when the control section 10 operates.
Please remember "○" when registering your reservation. In this example, the storage section 9 has a capacity of storing four reservations, and FIG. 4 shows that one reservation is registered.

The receiving device 6 receives a predetermined broadcast program, and includes a receiving section and/or a recording section (eg, a video tape device, a tape recorder device, etc.). The receiving device 6 turns on and off the power, and controls the broadcast frequency (
channel) settings, and preparation and start of reception and recording.
The termination is automatically controlled by the reception control device 5.

Next, the operation will be explained.

FIG. 5 is a timing chart showing the broadcasting of broadcast programs and reception control information, and the operations of the reception control device and the reception device in 1) series.

In FIG. 5, when the reception reservation is not registered in the storage section 9, the power of the reception control device 5 is turned off. Here, the receiver manually turns on the power of the reception control device 5,
Assume that you have registered a reservation for program B of 1-1. Broadcast control device 2
sends reception control information (reception preparation information) that instructs reception preparation in order to foretell the start of the broadcast of program B at a predetermined time earlier than the time @ when the broadcast of program B starts. , Also, the time immediately before the start of broadcasting of program B■
receives reception control information (reception start information) that instructs to start receiving the program B, and reception control information (reception end information) that instructs to end the reception at the time point (■) when the broadcast of the program B ends. It is sent to the control device 5.

The reception control device 5 monitors the reception control information, detects a preview of broadcasting of program B based on reception preparation information, detects the start of broadcasting of program B based on reception start information, and detects a preview of broadcasting of program B based on reception end information. Detects the end of.

On the other hand, the receiving device 6 is powered on by the advance detection signal from the reception control device 5, selects program B based on the start detection signal and receives or records the broadcast, and ends the reception and turns off the power by the end detection signal. .
