Abstract

PURPOSE:To accomplish the picture recording of a TV program desired to picture record even though the broadcasting time of the reserved program is changed by assigning a peculiar program code to the TV program, and controlling the execution of the picture recording by receiving a code signal corresponding to this code at the time of the beginning and the end of the program. CONSTITUTION:A TV broadcast transmitting side is provided with a signal transmitting part 1, and a picture recording device is provided with a signal receiving part 2, a program code converting part 3 to convert the received signal into the program code, a set number code storing part 4, a program code comparing part 5 and a picture recording control part 6. At the time the broadcasting through such constitution, the signal corresponding to a number code peculiar to the program is transmitted from the transmitting part 1 at the time of the beginning and the end of the program. When this signal is received, the signal received by the receiving part 2 is converted into the code by the program code converting part 3, and is compared with a picture recording reservation number stored previously in the storing part 4 by the comparing part 5. At the time of coincidence, the picture recording is started by the control part 6, and when the code is received again, the picture recording is stopped.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] The present invention relates to television broadcasting, and particularly to a television broadcast recording control system that controls recording execution in accordance with changes in program broadcast times.

[Prior Art] In a conventional recording control system for television broadcasting (hereinafter referred to as TV broadcasting), scheduled recording of a television program (hereinafter referred to as TV) is based on the channel day, start time, and end time of the TV program to be recorded. The time was set on the recording device, and the execution of recording was controlled by the timer function.

[Problems to be Solved by the Invention] In the conventional TV broadcast recording control system described above, scheduled recording was controlled by a timer function, so if the broadcast time of the program to be recorded changes, the scheduled recording is not scheduled. The disadvantage was that some of the programs that were originally scheduled were missing partially or completely.

[Means for Solving the Problems] The gist of the present invention is to provide a television broadcast transmitting station including a signal transmitting unit that broadcasts a unique program code assigned to a television program as a program signal along with a television signal, and a television broadcasting station scheduled to be recorded. a recording device that stores a program code assigned to a television program and controls the start and end of recording when a program code specified by a program signal broadcast together with the television signal matches the stored program code; This means that the system has been constructed with the following features.

[Example] Next, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing one embodiment of the present invention. In the TV broadcast recording control system of the present invention shown in the figure, the TV broadcast transmitting side includes a signal transmitting section 1, and the recording device includes a signal receiving section 2, a program code converting section 3 that converts the received signal into a program code, and a set program. Code storage section 4 and program code comparison section 5
and a recording control section 6.

During TV broadcasting, the signal transmitter 1 transmits a signal corresponding to a program code specific to a program at the start and end of the program. The signal is received by the signal receiving section 2 and converted into a corresponding program code by the program code converting section 3. The program code is compared with the program code of the program to be recorded stored in the set program code storage unit 4 at the time of recording reservation in the program code comparison unit 5, and if they match, the recording control unit 6
and start recording. Recording is terminated when the program code signal is received again.

FIG. 2 shows an example of the case where a program code signal is transmitted in the TV broadcast recording control system of the present invention.

A program code signal indicating the start and end times of a program is transmitted in eight parts during the blanking period of the TV signal.

The recording device receives this TV signal at a signal receiving section 2, restores it from the program code signal received in eight separate times during the retrace period, and converts it into a program code at a program code converting section 3.

[Effects of the Invention] As explained above, the present invention assigns a unique program code to a TV program, and executes recording by transmitting a program code signal corresponding to the program code at the start and end of the program. By controlling the TV set for recording,
This has the effect that even if there is a change in the broadcast time of group s, the desired TV program can be completely recorded.

[Brief explanation of the drawing]

FIG. 1 is a block diagram showing an embodiment of the TV broadcast recording control system of the present invention, and FIG. 2 is a flow chart explaining the procedure for forming a program code. Signal transmission section, signal reception section, program code conversion section, set program code storage section, program code comparison section, and recording control section. Figure 1

Claims (1)

[Claims] A television broadcast transmitting station including a signal transmitting unit that broadcasts a unique program code assigned to a television program as a program signal along with the television signal; A television broadcast recording control system comprising: a recording device that controls the start and end of recording when a program code specified by a program signal broadcast together with the signal matches the stored program code.
