ン表示する。The infrared rays corresponding to the depression of a predetermined key from the remote control transmitter (3) are demodulated by the remote control receiver (41) to become a remote control signal as shown in FIG. As the remote control signal, a reader code, a custom code, an inverted custom code, a data code, and an inverted data code are output at a time of 67.5 mS, and thereafter, when the key is continuously pressed, a serial code is continuously output every 108 mS. The code is "0" when the pulse pause period is short and "1" when the pulse pause period is long.
It is a PPM (Pulse Position Modulation) type, and each code is 8-bit binary data. Then, this remote control signal is decoded by the microcomputer (42),
For example, a channel selection command is supplied to the channel selection circuit (43) to select a predetermined channel, and a character signal generator (45) is controlled to generate a channel character signal, which is then mixed by a mixing circuit (46). And superimpose it on the video signal and display it on-screen on the CRT (47).

When the CPU (42) detects this data, it recognizes that the second and subsequent blocks are not character codes but character display control data. Then, after the second block, the data representing one instruction in 8 bits follows the leader code.
It is sent by the PPM method. For example, assuming that 16 characters are displayed on one line, the data necessary for displaying one line is shown in FIG. With this data, for example, in blue letters on the CRT (47) Is displayed on-screen.
