Next, the display states of the respective display devices will be described with reference to the flow charts of FIGS. First, with reference to FIG. 2, a display state of the VTR selection indicator (VTR selection indicators corresponding to the VTRs 4, 5 and 6 and also serving as selection buttons as described above) 16 will be described. VTR
In the selected states of 4, 5 and 6, the status sense command from the CPU 7 is transmitted to the VTRs 4, 5 and 6, respectively, so that the selected states of the VTRs 4, 5 and 6 are, for example, one frame (= 1/30). Every second),
The detection result (return value st) is stored in the RAM 9. In this case, when the VTRs 4, 5 and 6 cannot be remotely controlled, the return value s stored in the RAM 9
t becomes "LOCAL", and if the return value st is not obtained within 1/30 seconds after the status sense command from the CPU 7 is issued, the return value st stored in the RAM 9 is "TIME OVER. ".

In step ST-1, the return value of the status sense stored in the RAM 9 is read out, and then S
Move to T-2. In ST-2, it is determined whether or not the return value st is "TIME OVER". If YES, the process proceeds to step ST-3, and if NO, step ST-
Go to 4. In step ST-3, the red LED is blinked and the green LED is turned off, and then the process ends. This indicates that the communication between the editing machine 1 and the VTR corresponding to the selection button is abnormal, or the power of the VTR is turned off. At step ST-4, the return value s
It is determined whether or not t is "LOCAL". If YES, the process proceeds to step ST-5, and if NO, the process ends. In step ST-5, both the red and green LEDs are blinked. This indicates that the VTR corresponding to the select button cannot be remotely controlled, that is, the VTR can be directly operated.

Then, both the red and green LEDs are turned off. This means that the switcher or mixer pressed by the control buttons of the switcher control indicator 17 and the mixer control indicator 18 is not remotely controlled.

Next, the display of the control states of the switcher control indicator 17 and the mixer control indicator 18 will be described with reference to FIG. In this case, the command generated at the timing required by the CPU 7 is transmitted to each switcher control display 17 and the mixer control display 18, and its response is the return value rt.
It is stored in the RAM 9 as n. When there is no response from the switcher control indicators 17 and the mixer control indicators 18 within the predetermined time, the return value rtn stored in the RAM 9 becomes "TIME OVER" and there is a response, but each switcher control indicator When the meaning of the transmitted command is not understood on the side of 17 and the mixer control display 18, RA
The return value rtn stored in M9 becomes "nak".

At step ST-1, a command is transmitted from the CPU 7 to each switcher control display 17 and mixer control display 18, and then the process proceeds to step ST-2. In step ST-2, after the return values rtn from the switcher control indicators 17 and the mixer control indicators 18 stored in the RAM 9 are detected, the process proceeds to step ST-3. In step ST-3, it is determined whether or not rtn is "TIME OVER", and if YES, step ST-
4 and if NO, it proceeds to step ST-5. In step ST-4, the red LED is blinked and the green LED is turned off, and then the process proceeds to step ST-5.
This means that the power of each switcher control indicator 17 and the mixer control indicator 18 is turned off, or there is an error in the communication between the editing machine 1 and each switcher control indicator 17 and the mixer control indicator 18. Indicates that there is. In step ST-5, it is determined whether or not the return value rtn is "nak". If YES, the process proceeds to step ST-6 and N
If it is O, it means the end. At step ST-6, the red and green LEDs are blinked together, and then the process ends. This indicates that the switcher control display 17 and the mixer control display 18 are not in the remote control enable state by the CPU 7.
