The operation of automatically searching for and transmitting a control code capable of remotely controlling an externally connected external recording device, confirming the operation, and setting the operation. 7 shows an example Z of a screen display when executing.

On these screens, character data is sent from the system control circuit 1E to the character signal generating circuit section 1G and displayed on the monitor 1C via the VTR section 1B.

Further, FIG. 3 executes the operation of automatically searching, transmitting, confirming the operation and setting the control code for remotely controlling the externally connected external recording apparatus according to the present invention. It is a flowchart which shows a process and is performed by the system control circuit 1E.

In the flowchart of FIG. 3, when the process is started, the switch SW is turned ON / O in step S1.
If the FF state is detected and the switch SW is ON, the process proceeds to step S2, where the search operation for identifying the remote control signal for controlling the external recording device is performed to control the external recording device. Select the appropriate remote control signal,
Thereafter, a remote control code search routine for controlling the external recording device using the selected remote control signal is executed. The details of this routine will be described later.

When the processing of this remote control code search routine is executed and completed, the search result is checked in step S3, and SEARCH FLAG corresponding to the result is set up.

When SEARCH FLAG is 1, it means that the external recording device and the manufacturer code transmitted from this device match, which means that the external recording device can be controlled by this device. Then, the process proceeds to step S4, an end screen as shown in FIG. 2C is output, and after the end screen is output, the process goes to step S6 to end the process.

This makes it possible to control the external recording device from this device thereafter.

On the other hand, in step S3, SEARCH FLAG is 0.
In the case of, this means that the remote control signal that can control the external recording device, that is, the manufacturer code is not included in the device, and remote control is impossible. In this case, the process proceeds to step S5, and as shown in (d) of FIG. 2, it is displayed that there is no corresponding manufacturer code and control is impossible. Then, the process proceeds to step S6, and the process ends. .

Next, the processing of the remote control code search subroutine executed in step S2 of FIG. 1 will be specifically described with reference to the flowchart of FIG.

In the figure, when the remote control code retrieval subroutine is started, first, in step S10, SEAR
Set CH FLAG to 0 and clear SRCHPT indicating the address of each remote control code indicating the ID of each manufacturer and model in the remote control pattern table.

In the remote control pattern table, SRCHPT
The remote control signal is assigned to each manufacturer and each remote control signal pattern type for remote control using as an address. In the example of the figure, a power ON command (P.ON Cmd) for turning the power ON and A power OFF command (P.OFF Cmd) for turning off the power is stored.

Then, in step S11, a code string which is assigned to each SRCHPT value and constitutes a remote control signal corresponding to each manufacturer and model registered in advance is read out, and as shown in FIG. 2 (a). , Is displayed on the monitor screen, and is transmitted to the external recording device in step S13.

In this process, the remote control signal read from the remote control pattern table and transmitted to the external recording device is a power-on command for turning on the power of the external recording device, and is currently displayed on the monitor screen. The manufacturer name, model name, and the power of the remote control signal corresponding to the code string of the selected and transmitted remote control signal are turned on.
Power on command (POWER ON command
Is being output) is displayed.

In step S14, it is determined whether or not a video signal is input from the external recording device to the video signal input terminal IF for a certain period of time. Specifically, the video signal input terminal I
The vertical synchronization signal (V-SYN
C), the input of the video signal is detected by determining the presence or absence of a specific signal such as the horizontal synchronization signal (H-SYNC).

If a video signal is detected in step S14 within a certain period of time, the process proceeds to step S15, as shown in FIG.
Power OFF to turn off the power, as shown in (b) of
Select the command and display on the monitor screen that the data is being sent to the external recording device, as shown in FIG. 2 (b). In step S16, the power supply nFF command (P.OFF) is sent to the external recording device. Send Cmd).

If the external recording device can be controlled by this device, the operation of the external recording device should be stopped by this, and the output of the video signal to the video signal input terminal IF should be stopped. Whether or not a video signal is input is determined (V-SYNC or H-SYNC is detected).

As a result of this discrimination processing, if no video signal is detected as a result (no SYNC), the external recording device is turned off by the power OFF command (P.OFF Cmd) transmitted in step S16, and the video signal of Since it can be determined that the output has stopped, it can be determined that the remote control pattern of the remote control signal currently being transmitted is compatible with the external recording device.

Therefore, thereafter, the external recording device is controlled by using the remote control signal in the remote control pattern of this SRCHPT type. Various control signals other than power ON / OFF for controlling the external recording device are stored in a ROM (not shown).
Are stored in advance, and control is performed using the command. Incidentally, this ROM may be shared with the remote control pattern table or may be a separate ROM.

Next, in step S18, SEARCH FLAG is set to 1 to indicate that a remote control pattern capable of controlling the external recording device has been detected, and the process returns to the process of the flowchart of the main routine of FIG.

On the other hand, returning to step S14, if the video signal (SYNC) is not detected, it means that the external recording device is not turned on by the power-on command (P.ON Cmd). Branch and SRCH
PT is incremented by 1 to SRCHPT1, another remote control code is read from the remote control pattern table and transmitted to the external recording device.

Then, in step S20, SRCHPT
> 10, that is, the address of SRCHPT is the last address SRCH
It is determined whether or not PT = 10 is exceeded.

If SRCHPT> 10, all the remote control codes in the remote control pattern table have been tried, which means that there is no compatible remote recording device, and the SEARCH flag remains 0, Returning to the main routine of FIG. 3, the main routine side performs a process of displaying the search end NG screen in step S5.

If SRCHPT> 10 is not satisfied in step S20, the process proceeds to step S11, and the new remote control code is subjected to the processing of steps S11 to S18 to be compatible with the external recording device. Determine whether or not.

In the process of step S17, when the external recording device does not respond to the output of the power OFF command (P.OFF Cmd) and the input of the video signal is not stopped (S
(YNC is present), it judges that the current remote control code does not match the external recording device, and branches to step S19 to transmit a new remote control code.

In this way, the above search process is repeated until a remote control code suitable for the external recording device is found.

Through the above processing, the remote control code stored in the remote control pattern table is sequentially read from the apparatus to the external recording apparatus, transmitted, the suitable remote control code is searched, and if there is a suitable one. , A message indicating that the maker code and type compatible with the external recording device and the maker code match is displayed ((c) of FIG. 2), and if there is no final match, there is no corresponding maker code, It is displayed that the remote control cannot be performed ((d) of FIG. 2).

As a result, the remote control code capable of controlling the external recording device can be automatically searched and selected from the device side, and at the same time, the user can be made aware of the process of the search operation.

After that, the external recording device 10 is controlled by various control commands according to the control code of the type set by the above processing, and the image data input from the input terminal 1F and the magnetic tape in the VTR portion 1B are recorded. The recorded image data is edited and the character signal generation circuit unit 1
Various image editing processes are performed in the VTR unit 1B such as superimposing character data and the like supplied from G.
