System) is used. This 5IRC5 system is a format of an infrared digital code remote control, and the code format is shown in FIG. This formant usually consists of 15 bits (or 12 bits), including a guide pulse (36) as an identification signal that specifies the start, and a 15-bit (or 12 pin) binary signal starting from 2° following this guide pulse. 7 using code
It has a data code (37) representing the control function in bits,
The 8 bits (or 5 bits) after this code represent the product category.The product code (38) represents one frame (45ms).
> constitutes. Using such a control signal for 5IRC3, when viewing information in each room (20) to (23) from a predetermined source in the master room (2), the control signal for each room (20) to (23) is controlled. Remote control (14a) ~ (1

), DAT deck (6), and VTR (8), the multilink center (3) organizes the 5IRCS signals from these remote controllers and sends them in series. For example, CD information, LD information, DA
T information and VTR information are sent in this order. 5I like this
As shown in the R5C control signal controller diagram, one frame is 45m5, but there are two or more coincidences in the line which increases certainty.

In this way, multiple rooms (20) (21) (22
)... The audio information (16) or video information (15) requested from the multi-link center (3) side can be sent to each room almost simultaneously in response to the 5IR5C control signal control child. However, as shown in FIG. 8, for example, the remote control (14a) of the room (20)
time t by the operation of . issue a command to request the performance of the CD player (4) to the multi-center (3) in the sister room (2), and then send the request command to the multi-link center (3) to the room (20).
It is assumed that audio information (16) is being sent from the CD player (4). Next is time. At time t1 after a later time has elapsed, the CD player (
I used the remote control (14tl) to stop the CD player (4) in order to listen to the audio information (16) in 4).
Even if you press CD player stop -4- (14b') from
) is transmitting audio information from the CD player (4), and Room (20) has a vested interest, so Room (20)
The configuration is such that it does not respond to commands in 1). Of course,
When a data transmission request command is issued from the room (22) to a different electronic device, such as a laser disk (LD) (9), at time 1+=j2, the multi-link center (3) transmits the data. , the CD source can be viewed in the room (20) and the LD source can be viewed in the room (22) at the same time.

As mentioned above, when listening in another room, or when two users' data requests overlap at almost the same time, there is a selection key that allows one user to select priority without giving priority in time. It may be more convenient to install one with a remote control.

The present invention has been made to achieve the above-mentioned needs, and its purpose is to avoid overlapping transmission data information requests in electronic devices in the master room (2) used by multiple users. It is an object of the present invention to provide a remote control device having a priority selection function that ignores vested rights based on temporal priority when the time priority is selected.

[Means to solve the problem]

As an example of the remote control device of the present invention, as shown in FIG. The receiving means (
25) to (27) via cables (18) and (19), transmitting source data from a plurality of subrooms (20) to (23) in a remote control device adapted to transmit data from the source sources to the cables (18) and (19). Command operation means (14) that ignores the transmission of data that has already been transmitted when transmission requests overlap.
d).

[Effect]

The remote control device of the present invention makes it possible for a person who has a remote control with a priority key in a sub-room to listen to information preferentially when the same information as audio or video information that is already being transmitted is desired. I made it so that what comes to me is what I get.
