The S-RAM 21 is a static RAM, and each VTR1 input from the mouse remote controller 11 is input.
The recording reservation time of 4 is stored.

The operation of this embodiment will be described below with reference to FIGS.
This will be described with reference to the flowchart shown in FIG. 1. Recording reservation (see FIG. 3) (1) Use the mouse remote controller 11 to display the operation interface of the VTR to be reserved for recording on the screen of the CRT 8 and start / end date / time, broadcast channel, speed (LP / Register SP or standard / double speed). The registered information is processed as one unit of recording reservation (S1).

(2) The registered reservation unit information is the CPU
It is stored in the S-RAM 21 via 12 (S2). (3) Next, the CPU 12 reads out the reservation unit information stored in the S-RAM 21 and sorts each reservation unit using the start time as a key (S3).

(4) Next, the CPU 12 causes the timer 17
With respect to the current time indicated by, the reserved unit that becomes the recording start time in the closest future is extracted. However, at this time, the reservation unit which is already prepared for recording is excluded (S4).

(5) Further, the CPU 12 determines whether or not the extracted reservation unit is already registered in the timer 17 (S5).

(6) Next, the CPU 12 registers the extracted reservation unit in the timer 17 if it is not registered in the timer 17. That is, the timer 17 is registered so that an interrupt signal is generated at a time of M seconds (for example, several tens of seconds) before the start of recording (S6). The recording reservation is completed by the above operation.

2. Interrupt generation from timer 17 (see FIG. 4) When the recording reservation is completed, the CPU 12 returns to a normal routine, and when an interrupt signal is generated from the timer 17, the CPU 12 reads the recording task program stored in the program ROM 19, The recording task of is activated and executed (S7).

When such processing is performed, the power sources of the video signal merge block 7, the CRT 8 and the like can be turned off, but the CPU 12 is always operated and
Must be in standby state.

However, for example, the interrupt signal of the timer 17 is also supplied to a power supply control circuit (not shown),
It is also possible to automatically wake up the CPU 12 based on this interrupt signal and then activate the recording task. Further, in the above example, the recording task is activated based on the interrupt from the timer 17, but by another method, the recording task is activated based on the interrupt from the timer 17. However, the recording task can be activated by another method (see FIG. 5).

For example, in the program ROM 19 in advance,
The state monitoring program is stored, and the CPU 12 starts the timer check operation based on the state monitoring program at the same time as the recording reservation is completed (S7A). The timer 17 measures real time and sends this time information to the CPU 12. The CPU 2 periodically compares the time information sent from the timer 17 with the reserved recording start time stored in the S-RAM 21 (S8A), and M seconds (for example, several tens of seconds) before the reserved time. Then start the recording task (S9
A).

3. Recording task (see FIG. 6) When the recording task is activated, reserved recording is executed as follows. (1) The CPU 12 determines whether or not another reservation unit exists in the S-RAM 21 (S10). Next, if another reserved unit exists, the reserved unit having the closest future recording start time is extracted and registered in the timer 17 (S11).

(2) Next, the CPU 12 causes the S-RAM 21
A processing flag is added to the reservation unit information of the VTR in which the recording is being executed (S12).

(3) Next, the CPU 12 causes the VT to be recorded.
A status notification command is sent to R via the control cable. In response to the transmitted status notification command, the VTR to be recorded transfers the current status, for example, the power off status, to the TV 5 side via the control cable. The CPU 12 saves the transferred current state of the VTR to be recorded in the S-RAM 21 in order to restore it at the end of recording (S13). Next, the CPU 12 causes the VT to be recorded.
A recording preparation command is transmitted to R to instruct the recording preparation operation (S14). The recording target VTR has completed a time-consuming preparatory work such as loading a tape and is in a recordable state, and the CPU 12 enters a timer check operation and waits until the time indicated by the timer 17 becomes the recording start time (S15). .

(4) When the time indicated by the timer 17 reaches the recording start time stored in the S-RAM 21, the CPU 12 sends a recording operation start command to the VTR to be recorded via the control cable. (S16,
S17). With this command, V which was in the ready state
TR starts recording.

(5) Next, the CPU 12 waits for the recording end time to come (S18). The CPU 12 has a timer 17
When the time indicated by is the recording end time stored in the S-RAM 21, the recording operation end command and the V before recording are sent to the VTR being recorded via the control cable.
Information indicating the state of TR is transmitted (S19, S20).
As a result, the VTR ends recording and returns to the state at the time of starting recording (S21). For example, if the power was turned off at the start of recording, the power is turned off.

(6) Further, the reservation information with the flag in the S-RAM 21 is deleted. This completes the reserved recording operation (S22).

Although the reserved recording is executed by the above-mentioned steps (1) to (6), even if the reserved recording times of a plurality of VTRs are overlapped, if the time division processing is performed, no problem will occur. Scheduled recording can be performed. In the above example, C
The PU 12 obtains the current state of the VTR to be recorded from the control cable, but it can also be determined from the input state of the video cable from the VTR to be recorded when the state notification command is transmitted.

4. Operation of sleep timer (auto power off) Auto power off of TV and VTR is performed as follows. (1) Register the sleep time (time to turn off the power) using the operation interface on the screen of the CRT 8.

(2) The registered sleep time is SR
It is stored in the AM 21, and at the same time, the CPU 12 starts the timer check by the status monitoring program.

(3) When the time indicated by the timer 17 reaches the set sleep time, the CPU 12 sends a power-off command to all the VTRs connected to the TV via the control cable. All VTRs are powered off by the power off command.

(4) Then, the CPU 12 sends a power-off confirmation command to all VTRs, confirms the power-off of all VTRs based on the response, and then turns off the power of the TV. This completes the automatic power off of the entire system.

As another embodiment of the recording reservation centralized management system for one or more VTRs according to the present invention, an audio device is connected instead of the VTR to record a radio program,
Applications such as starting a CD player and listening to music when the desired time comes are also possible.

Further, by applying the power ON / OFF control system, it is possible to perform centralized control for starting and stopping various devices in the home at arbitrary times.
