An operation key button was provided to send commands such as a playback operation or a recording operation on the main body side, and the main body side received these commands to perform various functions such as a play operation and a recording operation.

However, in such a conventional system, when an operation commanded from the remote control transmitter side is performed on the main body side, a key operation related to a predetermined function should not be performed while the operation is in progress. It was difficult to avoid the problem that the operation being performed in the system was stopped or malfunctioned.

In particular, in this case, the main body of the system is recording important programs, but the user may unknowingly press the fast-forwarding key to make the recording not proceed properly.

As such, no conventional means have been devised for such a problem, and thus it is not preferable.

The object of the present invention has been developed in view of the above-mentioned conventional problems, which forms an LED key in the remote control transmitter, and these LED keys allow the user to turn on only the minimum operable keys related to the operation of the main body side. Since only one of the lit keys can be selected to provide a command, it is possible to reduce the probability of malfunction of the key operation with the convenience of using the key in such a system.

The present invention provides a remote control transmitter which is provided on the remote control transmitter side to implement the object of the above example and has a flashing light receiving circuit in which the LEDs related to the operation performed on the main body side in the microprocessor on the main body side receive the flashing light instruction.

Hereinafter, by referring to this in more detail with the accompanying drawings will be understood more specific features of the present invention.

That is, Figure 3 shows a remote control transmission and reception system circuit according to the present invention.

Here, the remote control is provided on the remote control transmitter side and has a flashing light receiving circuit (1) for receiving a flashing command of LED keys related to the operation being performed on the main body side in the microprocessor 32 of the VCR unit of the main body. It consists of a transmitter and a flashing light transmitting section 2 provided on the main body side to generate a flashing command signal of the microprocessor 32 and to send it to the flashing light receiving circuit 1 on the remote control transmitter side.

In addition, the flashing light transmitting unit 2 is connected to the transmitter driving circuit 22 which receives key data related to the system operation from the microprocessor 32 on the VSI side, and from the output of the transmitter driving circuit 22 to the remote controller. It consists of a lighting lamp transmitter 21 which sends predetermined lighting information to the lighting lamp receiving part 11 of a transmitter side.

On the other hand, the microprocessor 42c and the like on the remote control transmitter side are equipped with the flashing processing program 100 of the fourth embodiment.

In this case, it is checked whether or not the power is turned off from the start step (step 101).

In the playback state in step 102, the contents of the keys operable in this state are referred to as the power key (PK), stop key (STK), fast forward key (FFK), rewind key (REWK), and still key (STIK). At this time, all of these LEDs are turned on (step 103), and all other keys are turned off (step 104).

When the power is turned off at the step 101, only the power-on key can be used on the remote controller, and only the LED of the power key is turned on (step 105), and the remainder is also turned off (step 104).

Similarly, in step 102, if NO is checked (step 106), if recording is enabled, the LEDs of keys that can be operated in the recording status key are turned on (step 107), and the flow proceeds to step 104, and in step 106 If no, the VSI side checks whether it is another mode (step 108), and if it is another mode, a series of processing is performed to perform the corresponding LED flashing operation.

In the present invention as shown in FIG. 3, when the remote control transmitter sends a predetermined command signal to the VSI side, the remote control receiver side reacts to the remote control receiver side as in the conventional method.

At this time, the microprocessor 32 at the VSI unit side turns on / off the corresponding operation contents according to the state of the operation at the VSIAL unit side currently being in the playback operation, the recording operation, or performing another mode. 2), the transmitter drive circuit 22 drives the lights on the transmitter 21 to provide information on the state of the operation on the VSI unit side. It is sent to the flashing light receiving unit 11 of 1).

When the lighting unit 11 provides this information to the microprocessor 42c, the microprocessor 42c drives the LED matrix 13 in accordance with the lighting system 100 of the fourth embodiment.

At this time, the microprocessor 42c distinguishes between the keys that are now operable and the keys that cannot be operated according to the operating state of the VSI part, and sends out a flashing operation command to the flashing driving unit 12 to turn on the LED lighting unit 12. Only the corresponding LED key is turned on in the matrix 13, and all other LED keys are kept off.

Therefore, the user can easily identify this state through the transmitter key portion 42a on the remote control transmitter side, which key is now a key that can be operated and which key is a key that cannot be operated.

On the other hand, the on and off operation of the above example is performed together with the on and off processing program 100, where the microprocessor 42c turns on and off the on / off transmission unit 2 side of the Vialal unit to determine whether the system of the Vialal unit is powered off. It checks in accordance with the contents of the information sent, and if it is not in the power-off state, checks whether it is in the playback state (steps 101 and 102)

In the above playback state, the microprocessor can be viewed as the power key (PK), stop key (STK), fast forward key (FFK), rewind key (REWK), still key (STIK), etc. At 42c, all of these LEDs are turned on, and all other keys are turned off (steps 103 and 104).

When the information of the power-off state is transmitted on the VSI part in step 101, only the power-on key can be used on the remote control transmitter side, so that only the LED of the power key is on, and the remainder is also off. (Step 104, 105).

Likewise, if the information is not in the playback state, it is checked whether it is the recording state information.In the recording state, the LEDs of the keys that can be operated in the recording state are turned on, the recording state is entered, and the V is not recorded. Check whether it is another mode information on the sial unit, and if it is another mode, the LED on / off operation of the corresponding remote control transmitter is performed.

In the present invention as described above, the key operation of such a remote control transmitter is made by turning on only the keys which can be operated in accordance with the state of operating in various modes on the set main body side of the apparatus in the remote control transmitter, such as a VSI equipped with a remote control transmission and reception system. It is easy to achieve this.

In addition, since the remote controller transmitter side can significantly reduce the probability of malfunctioning due to unnecessary operation of the main body such as VSI or the like, a key operation reliability can be satisfactorily secured when using such a system.
