Here, the case where the present invention is applied to a VTR will be described as an example of the present invention.

FIG. 1 is a diagram showing a schematic configuration when the present invention is applied to a VTR.

In FIG. 1, reference numeral 1 is a VTR main body portion, 2 is a main body side operation portion for performing an operation start operation at the time of recording or reproduction of the VTR main body portion 1, and 3 is described later according to an operation of the main body side operation portion 2. The main body side system controller 4 outputs the operation command signal C to the main system controller 5 and causes the main body side display unit 4 to be described later to display in response to the display command signal B from the main system controller 5. The main body side display section 5 controlled by the system controller 3 supplies a clock pulse A, outputs a display command signal B according to the operation state of a recording / reproducing section described later, and the main body side system controller 5 and the later described. The operation of the recording / reproducing unit 6 is controlled according to the operation command signal C from the remote controller side system controller 9, and the main body side system controller 5 or the remote controller side system controller 5 is operated. The main system controller that controls the exchange of each command signal of the video controller 9, 6 is a recording / playback unit that performs the recording or playback operation of the VTR main unit, 7 is a remote control unit, and 8 is the recording or playback of the VTR main unit 1. Remote control side operation unit for remote control to start the operation of
Reference numeral 9 outputs an operation command signal C to the main system controller 5 in response to an operation of the remote controller side operation unit 8 or displays a display on a remote controller side display unit 10 described later in response to a display command signal B from the main system controller. A remote control side system controller to be executed, 10 is a remote control side display unit controlled by the remote control side system controller 9, 1
Reference numerals 1 and 12 are OR gates, and 13 is a switch that is turned on when the remote control unit 7 is connected.

When the remote control unit 7 is not connected, the operation of the recording or reproduction and the display of the operation state are performed by the main body side operation unit 2 and the main body side operation unit 4. When the remote control unit 7 is not connected, the switch When 13 is turned off and this state is detected by the main system controller 5, the transmission completion signal is exchanged between the main system controller 5 and the main body side system controller 3 on line D in the figure. That is, when the main body side operation unit 2 is instructed to perform operations such as recording, reproduction, fast-forwarding, rewinding, stillness, and slowing, a transmission confirmation signal from the main body side system controller 3 passes through the line D and the OR gate 12. Is output to the main system controller 5, and the main system controller 5 is interrupted by the signal, and the main system controller 5 becomes ready to receive the operation command signal C. This time, conversely, the main system controller 5 sends a transmission confirmation signal through the line D. Is output to inform the system controller 3 on the main body side that the system is ready to receive data. After that, an operation command signal C corresponding to the instructed operation is output from the main body side system controller 3 and input to the main system controller 5 via the OR gate C. After confirming the operation state of the recording / reproducing unit 6, the main system controller 5 causes the recording / reproducing unit 6 to perform an operation according to the operation command signal, and this time the main body side system controller 3 receives the transmission confirmation signal through the line D. It is output and interrupts the system controller 3 on the main body side. And the main body side system controller 3
When is in a receiving posture, a transmission confirmation signal is output from the main system controller 3 to the main system controller 5 through the line D. Thereafter, the main system controller 5 outputs a display command signal B according to the operating state of the recording / reproducing unit 6 to the main body side system controller 3, and the main body side system controller 3 operates on the main body side display unit 4 in response to this. Is displayed.

Next, the case where the remote control unit 7 is connected will be described using the operation flow chart of FIG.

In FIG. 2, when the operation of the main system controller 5 is started, it is detected whether the switch 13 is in the ON state or not. If it is not in the ON state, it is considered that the remote controller 7 is not connected, and the main body system controller 3 operates as described above. In addition, switch 13
In the ON state, it is considered that the remote controller 7 is connected, and the transmission confirmation signal is supplied from the main system controller 5 to the remote controller system controller 9 through the line E. After that, when the remote controller side system controller 5 is activated, a transmission confirmation signal is output to the main system controller 5 and the remote controller 7 instructs and displays an operation, but the remote controller side system controller 9 does not output a transmission confirmation signal. If there is an abnormality, it is determined that the remote controller 7 is out of order, and the operation is switched to the operation by the system controller 3 on the main body side. In the normal case, after the transmission confirmation signal is exchanged on the line D and the interruption is completed, the main system controller 5 outputs an operation command signal B for stopping the display operation to the main body system controller 3 and the main body system controller The display operation of 3 is stopped. At this time, the display operation of the system controller 3 on the main body side is stopped, but an operation instruction by the operation unit 2 on the main body side can be performed. Further, the main body side display unit 4 may suppress the display at the normal time, but may display such that it is possible to confirm that the remote control unit 7 is in the connected state.

After the display of the main body side display section 4 is suppressed as described above, the operation instruction operation by the remote control side operation section 8 and the operation display by the remote control side display section 10 in the remote control section 7 are performed by the main system controller 5 in the line E. It is controlled by the remote controller system controller 9 through the exchange of the transmission confirmation signal. Since the system controller 3 on the main body side and the system controller 9 on the remote controller side perform the same operation, the operation is the same as described above. In this case, since the system controller on the main body side and the system controller on the remote control side may be the same, the same operation and display can be performed on each display unit and the operation unit. In other words, the presence / absence of a tape cassette, the battery check, the condensation of the cylinder, the display of information such as the counter can be displayed on the remote controller side display unit 10.

FIG. 3 is a connection diagram of a VTR and a remote control device to which the embodiment of the present invention is applied. The switch 13 is a remote control unit 7 and a VT as shown in FIG.
If the connector 15 of the multi-cable 14 for connecting to the R body 1 is provided and the connector 15 is connected so that it is turned on, the operation can be easily performed. Further, the present invention is applicable not only to wired as shown in FIG. 3 but also to wireless. In this case, the operation and display by the remote controller may be started when a predetermined signal or light generated by the remote controller is received.

Although the VTR has been described as an example in the embodiment, the remote operation is performed, and the operation state of the main body by the operation is displayed. For example, in the case of a video disk device or the like, application of the present invention greatly improves usability. To do.
