Therefore, it is possible to set a program reception reservation or a program deletion reservation, and to make a reservation reception by the set program, and to display on the display screen that the program is being deleted while the program is being deleted. It is possible to eliminate the mistaken state of the TV as a malfunction.

[0006]

FIG. 1 is a block diagram showing an embodiment of a program reservation receiving system according to the present invention. The television broadcast signal input via the input terminal 1 is selected and received by the tuner unit 2, and the received signal is demodulated by the video signal demodulation circuit 3 to output a video signal, which is input to the switching circuit 4. . The reservation setting signal is constituted by a code signal indicating reservation of program reception or program erasure reservation, reservation channel, date, time, program length, and the like. 5, and the reception unit 5 extracts a reservation setting code signal. For example, a microcomputer is used as the control unit 6, and a reservation setting code signal input from the receiving unit 5 is determined by the determination unit 11, and program reception reservation is performed.
Alternatively, discriminating a program for erasure reservation, a reservation channel, a date, a time, and a signal representing the length of the program are each determined,
A reservation is set in a reservation setting unit 10 including a memory and a timer via the control unit 6.

[0007] The control unit 6 reads the reservation setting code signal set in the reservation setting unit 10, outputs a control signal at the time set by the reservation setting signal based on the time information from the timer, and inputs the control signal to the tuner unit 2. When the reception of the program is reserved, the reserved channel can be selected and the signal selected by the video signal demodulation circuit 3 is demodulated into a video signal. Output. When a program is scheduled to be erased, the control signal input from the control unit 6 to the tuner unit 2 prevents the tuner unit 2 from selecting the channel. For example, no signal may be set, or tuning may be shifted.

Further, a control signal is output from the control unit 6,
The signals are input to the switching circuits 4 and 8 and the on-screen signal generator 7. The switching circuit 4 receives the video signal from the video signal demodulation circuit 3 and a separately generated black level signal.
The switching circuit 4 is switched by a control signal from the control unit 6 to select and output a black level signal. The on-screen signal generator 7 generates a display signal indicating that the program is being erased and inputs the signal to the switching circuit 8. The switching circuit 8 switches the black level signal input from the switching circuit 4 at a predetermined position, and performs on-screen switching. The display signal from the signal generator 7 is output. Therefore, if the display is displayed on the display unit based on the output from the switching circuit 8, the display screen becomes a black level, and a display signal indicating that the program is being erased can be displayed at a predetermined position on the display screen. It is possible to eliminate the possibility of being mistaken for the failure state of the above.

In the present invention, a remote control signal and
Then, for example , it is possible to use a code signal that is compression-encoded indicating the reservation of the reception of the program or the deletion of the program, the reservation channel, the date, the time, and the length of the program. In this case, the decoder unit 9 provided with a conversion table for converting the compression coded code signal into a remote control code signal
Is connected to the control unit 6, and the compression coded code signal received by the reception unit 5 is input to the control unit 6, and the control unit 6 decodes the remote control code signal corresponding to the input compression coded code signal. It is read from the unit 9 and discriminated by the discriminating unit 11 to distinguish between program reception reservation and program deletion reservation.
The reservation channel, the date, the time, and the signal indicating the length of the program are determined, and the reservation is set in the reservation setting unit 10 via the control unit 6. In the same manner as described above, the control unit 6 reads out the reservation setting signal set in the reservation setting unit 10 and controls each unit, thereby making it possible to program-control the reception of the television signal.

[0010] A plurality of television receivers used in a home may be able to simultaneously receive program reservations. In this case, a transmission unit 12 for wirelessly transmitting a remote control signal is provided and connected to the control unit 6, and each television receiver is configured as shown in FIG. 1, and the reception unit 5 is connected via a wireless LAN or a home bus. Enable to receive remote control signals. The reservation setting section 10 of one television receiver sets reservations of a program reception reservation or a program erasure reservation distinction, a reserved channel, a date, a time, and a signal indicating the length of the program.

The control section 6 reads the reservation data set in the reservation setting section 10, reads a remote control code signal corresponding to the read reservation data from the decoder section 9, converts the reservation data into a remote control code signal, and 12
From a remote controller via a wireless LAN or a home bus. The reception unit 5 provided in another television receiver receives the remote control signal, and the reservation data is similarly set in the reservation setting unit 10 provided in the same television receiver. Program control becomes possible.

[0012]

As described above, according to the present invention,
It is possible to set a program reception reservation or a program deletion reservation. Especially when a program deletion reservation is made, the channel cannot be selected and the display screen becomes black level and the program is being deleted. Can be displayed, and a program reservation receiving system can be provided which is not mistaken for a failure state of the television.
