Abstract

PURPOSE:To simplify the setting of a program by providing a reception state setting means setting a reception state according to a reservation program read from a program memory, detecting the end of the reservation program and resetting a program read means. CONSTITUTION:An AC power supply fed from an AC outlet 22 of a VTR 20 is given to a power supply section 19 of a receiver 10 via a power cord 18. Thus, the power for the receiver 10 is turned on from a video recording start time to an end time based on a timer program set by a timer 21 of the VTR 20. The power supply section 19 leads a signal PS for ON/OFF corresponding to the ON/OFF of the power supply supplied from the VTR 20 to a control section 15. The control section 15 reads a reservation program written in a program memory 1 sequentially every time the AC power rises and introduces channel information CH and reception mode information MS set to each program to a tuner 11 and a video audio circuit 13 respectively.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a reception program reservation device for a satellite broadcast receiver or the like.

[Prior art] VTR and radio-sized cassette tape recorders are
Many devices have a built-in timer to schedule or record programs. When using the timer, the reception channel, day of the week, start time, end time, etc. are set (reserved) in the program memory in advance.

Many standalone receiving devices, such as TV tuners and radio tuners, that do not have recording or recording functions do not have a built-in timer. To use these receivers in conjunction with a recording or recording device with a built-in timer, connect the AC power plug of the receiver to an AC outlet that is linked to the timer of the recording or recording device. , turn on the timer to activate the receiving device and recording/recording device, and record the reception output.

For example, if you want to schedule recording by linking a satellite broadcast receiving device that does not have a built-in timer with a VTR, you can select the receiving channel, audio mode (A mode, B mode), audio multiplex broadcast content (stereo broadcast, double The receiving status of audio broadcasts, etc. is set in advance in the program memory of the receiving device. When the VTR's timer is turned on and the VTR's AC power output is supplied to the receiving device, the receiving device is set to a programmed receiving state, and the receiving output is recorded by the VTR.

The above-described program reservation for the satellite broadcast receiving device can be set for a plurality of programs (events).

A plurality of reserved programs are sequentially selected each time the timer-on power of the VTR is turned on. Therefore, if four programs are programmed, four time slots corresponding to the timer of the VTR are set. The first to fourth reserved programs of the receiving device are recorded in order from the earliest of these four time slots.

[Problems to be Solved by Invention E] As mentioned above, in a receiving device that does not have a built-in timer, a program is reserved in advance every time the main power is turned off and on from an external device (recording device) that has a built-in timer. The received state is set and the device is activated.

However, for example, if you want to record programs in four different time slots every day for about a week, you will need to perform program reservation operations for 28 times, which is very complicated.
If the number of programs that can be stored in the program memory is limited, it will not be possible to reserve all of them.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a program reservation device that requires a small program memory capacity and that allows easy program reservation operations.

[Means for Solving the Problems] The program reservation device of the present invention has the following features as shown in FIG.
A program memory 1 is provided which sequentially stores reception reservation programs P1, P2, P3, . . . .

Each program PL, P2, P3, . . . is read out in order by the reserved program reading means 2.

The reservation program reading means 2 increments addresses A1 to An for sequentially reading out the reservation programs stored in the program memory each time a timer-controlled power supply supplied from an externally connected timer built-in device is turned on.

The reception state is set according to the reserved program read from the program memory 1.

Setting means 3 sets the reception channel, reception mode, etc. Further, the reception state setting means 3 detects the end of the reserved program and resets the program reading means. Therefore, the reception reservation program set in the program memory 1 is read out repeatedly.

[Operation] When recording a program that is broadcast at the same time every day, it is sufficient to store one day's worth of received programs in the program memory 1.

When power is supplied from an external device with a built-in timer and is turned on and off by timer control at the same time every day,
The reception status based on the same reservation program is set in the same time zone each time.

Therefore, the program reservation operation is easy, and even when a plurality of programs to be broadcast at the same time every day are reserved and recorded on a weekly basis, the memory capacity is small.

[Embodiment] FIG. 2 shows an embodiment in which the program reservation device of the present invention shown in FIG. 1 is installed in a satellite broadcast receiving device.

The satellite broadcasting receiver 10 shown in FIG. 2 includes a tuner circuit 11, and a received signal from an outdoor antenna unit 12 is transmitted to the tuner circuit FI! The channel is selected at step 111, and the selected output is demodulated at video/audio chart 813 and then output to the outside. The tuner circuit 11 is a synthesizer tuner, and the local oscillation frequency etc. are controlled based on the tuning information CH from the control section 15. The control section 15 is composed of a microcomputer, and provides channel selection information to the tuner circuit 11 in response to operations on the operation keys 14 including the channel selection buttons. Further, in response to a mode setting operation using the operation key 14, the control unit 15 controls the audio mode (
A mode, B mode) and the contents of audio multiplex broadcasting (stereo broadcasting, dual audio broadcasting), etc. receive mode setting information MS is supplied to the video/audio circuit 13. The reception channels, reception modes, and number of programs that correspond to the operation of the operation keys 14,
The repeat mode is displayed on the display section 16 according to the display signal DS from the control section 15.

Operation-4-14 is the program reservation key (program start, setting, cancel, end) and the repeat mode key (
(repeat mode setting, cancellation).

The reception reservation program set using the operation keys 14 is stored in the program memory l from the control unit 15.

When making a scheduled recording, the satellite broadcast receiving device 10 and VTR
20. The VTR 20 has a built-in timer 21 that can set the start time and end time of recording for each of a plurality of events. An AC power outlet 22 is provided on the back side of the VTR 20, and an AC power source that is turned on and off in conjunction with the operation of the timer 21 can be taken out from this AC outlet 22. Therefore, when performing scheduled recording, the power plug 17 of the receiving device 10 is inserted into the AC outlet 22 of the VTR 20.

At the same time, the output of the video/audio circuit 13 of the receiving device 10 is supplied to the external input of the VTR 20.

AC supplied from the AC outlet 22 of the VTR 20
Power is supplied to the power supply unit 19 of the receiving device 10 via the power cord 18 . Therefore, based on the timer program set in the timer 21 of the VTR 20, the receiving device 10 is powered on from the recording start time to the recording end time. The power supply section 19 derives an on/off signal PS corresponding to the on/off state of the power supplied from the VTR 20 to the control section 15 .

The control section 15 includes the reservation program reading means 2 and reception state setting means 3 shown in FIG.

These means 2.3 are realized by a program written in the ROM of the microcomputer.

Therefore, the control unit 15 sequentially reads the reserved programs written in the program memory 1 every time the AC power is turned on, and transmits the channel information CH1 reception mode information MS set for each program to the tuner 11.
, to the video/audio circuit 13. This allows the VTR
Each time recording of VTR 20 is started, the reception state of receiver 10 is set according to the reservation program, and the video and audio of the reserved program are successively recorded on the magnetic tape of VTR 20.

Furthermore, when the repeat mode is set using the operation key 14, the control unit 15 detects the end of the program in the program memory 1 based on an end mark E indicating a blank space in the memory segment, an all-zero code, etc. , when detection occurs, the read address of the program memory 1 is reset to A (first program P1).

(2) Therefore, from the next power up, the reception state is set repeatedly from the first program P□.

Next, the operations for reserving a program and setting the repeat mode will be explained with reference to the operation procedure flowchart shown in FIG.

First, the start key is pressed to shift from the normal reception state to the program setting state (steer knob 530). Here, set the reception status for program reservation in step 5.
31), the reception state setting data is stored in the memory by operating the program setting key (step 532).

Furthermore, after repeating the operations of steps 831 and 832 and setting a predetermined number of programs, the program setting cancel key is pressed to shift from the program setting state to the repeat mode setting state (step 533).

In this state, set the repeat mode. That is, to set the repeat mode, press the repeat mode setting key (step 534), and if not to set the repeat mode, press the repeat mode cancel key (step 535). Finally, the end key is pressed to end the program setting operation and transition to the normal reception state (step 536).

Next, FIG. 4 shows a flowchart of the program operation of the satellite broadcast receiving apparatus.

First, the program reservation and repeat mode settings are completed as described above (step 540), and then the calling program number n is set to O (step 541).

Here, when the main power of the receiving device 10 is turned off (step 542), the programming operation of the receiving device simultaneously enters a standby state (step S43>. Next, the VTR 20
When the timer 21 is turned on and the main power of the receiving device IO is turned on (step 544), the CPU of the control section 15
counts up the called program number n (step S45) and determines whether the program with that number is set in memory l (step 546).Here, if the program is stored in memory, Set the pre-programmed reception state (step 549), turn on the power (step S50), and then switch to program standby again when the main power of the receiver 10 is turned off by the timer 21 of the VTR 20 (step 542). state (step 543), and the above-mentioned operations are repeated.

If it is determined in step S46 that the program with the calling program number is not stored in memory, the calling program number n is returned to number 1 (step S46).
48) Set the reception state (step S39) and turn on the power (step 550). Also, step 847
If it is determined that the program is not in repeat mode, the series of programs is terminated without turning on the power.

[Effects of the Invention] Since the present invention is configured as described above, if you want to run the same program repeatedly, you only need to perform the program reservation setting operation once, and you can run the same program multiple times. Since there is no need to set any settings, the program setting operation is extremely simple. Furthermore, since it is not necessary to set a program for repetition, it is possible to perform program operations a large number of times with a small memory capacity.
