In the example of FIG. 3, the cursor 6-6 is placed on a character pattern 6-2 indicating a television receiver. When the input command key 5-4 in Fig. 2 is operated in this state, the CRT
The screen changes to the television character pattern screen 7 shown in FIG. Similarly, move the cursor 6-5 onto the character pattern you wish to operate and input the input command key 6-4. In the example of FIG. 4, the cursor 6-5 is located on the channel 20 character pattern 7-4, so when the input command key 5-4 is operated, channel 2 is selected. At the same time, the color of this character pattern 7-4 is changed to the color of other character patterns (indicated by diagonal lines in FIG. 4) to indicate that channel 2 is currently being received.

In Figure 3, 6-1 indicates the character pattern of the television and AVC3 equipment connected to the television;
2 is the character pattern for f-rev, 6-3 is for VTR, and 8-4 is for VHD.

In Figure 4, 7-1 indicates a character pattern indicating the operation contents of the TV, and 7-2 indicates the power ON/OFF.
17-3 to 7-14 are channel/L/numbers, 7-15.
7-21 is for volume up and down, 7-16.7-22 is for brightness up and down, 7-17.7-23 is for color up and down, 7-18.7-24 is for tint up and down. Down, 7-20 is a character pattern that means Mi, -to OON and OFF, and 7-26 means off timer 〇〇N and OFF.

Also, 7-27 is a character pattern indicating the end, and when this is selected, a character pattern screen 7 indicating the operation contents of the TV is displayed.
disappears and the screen returns to the device menu pattern screen 6 shown in FIG.

FIG. 5 shows a character pattern screen that displays the operation contents of the VTR when VTR is selected by aligning the cursor 6-5 with the VTR character pattern 6-3 in FIG. In Fig. 5, 8-1 is a character pattern indicating the operation contents of the VTR, 8-2 is the power ON and OFF, and 8-4
~8-15 is the channel number, 8-16 is the playback, 8-1
7 is stop, 8-18 is recording, 8-19 is pause, 8-
2o is a character pattern 0 that indicates the operation contents of a frame-by-frame VTR, and 8- is a character pattern for "end".
3 is a character pattern to be selected when this character pattern screen 8 is no longer needed.
6 and input command using the input command key 6-4 shown in FIG. 2 returns to the character pattern screen 6 of the equipment menu shown in FIG.

Also, returning to FIG. 1, numeral 4 indicates a VTR.

The input terminal 4-1 of the VTR 4 is connected via the RF multiplied signal output terminal 2-16 from the distributor 2-1 of the television receiver 2.

This is the channel selection section that controls the

On the other hand, when the input command key 6-4 is operated while the cursor 6-5 matches the character pattern 6-3 of the VTR in FIG. In this state, for example, if the reproduced character pattern 8-16 is selected with the remote control transmitter 3, the remote control signal is transmitted to the remote control amplifier 2-10.
V
The signal is sent to the control signal generator 4-12 in the TRA. Based on the sent control data, the control signal generating section 4-12 switches the signal switching section 4-9 to the lower side, connects it to the reproduction processing section 4-10, and transmits the reproduced video signal from the terminal 4-20 to the terminal 2-. 1
9, the video signal switching section 2-9. Signal processing section 2-5
．． The signal is supplied to the CRT 2-7 through the switching section 2-0.

Here, the terminal 2-17°2-1 of the television receiver 2
8 is a through-in/through-out terminal for connecting to other equipment, and terminals 4-21 and 4-22 of the VTR 4 are also similar terminals. In addition, the remote control amplifier 4- in the VTR4
13. The waveform shaping section 4-14 and the code decoding section 4-15 may not be provided. Remote control amplifier 2 for television receiver 2
-10° waveform shaping section 2-11. Code decoding 2-12 may be used in common. The control signal generator 4-12 in the VTRJ controls each function of the VTR 4, and
Performs input/output data processing of signals to the data bus. The control signal generating section 2-8 of the television receiver 2 also controls each section of the television, and also performs input/output data processing of signals to the data bus.

Further, 2-14 is a memory for storing character patterns, and 2-13 is a memory for storing character patterns.
The output signal Y11 is a switching signal for superimposing a character pattern signal on a video signal.

In the conventional example, two remote control transmitters as shown in Fig. 7 and Fig. 8 are required, and the number of keys is 47 just to operate the TV and VTR. In device 3, all functions of each device can be operated with 8 keys, and the operability is much better. Furthermore, even if a VHD function is added, the transmitter shown in FIG. 2 can still be operated using eight keys.

As described above, the remote control device of the present invention can be operated with a small number of keys even if there are many devices to be controlled and many operation functions, and the operation contents can be displayed in a large size on the CRT screen. This makes it possible to create an easy-to-understand and inexpensive system without having a separate remote control transmitter for each device.
