A better way than that is to make the sound of the person appearing on the screen to be made by a similar person to improve the real feeling. For example, in the case of a puppet show in which a puppet appears on the screen, a realistic puppet show can be provided by making a real puppet (or puppet) sound instead of a doll in the screen. . In this way, the person (s) and the doll (s) on the screen can interact with the real doll (s) off the screen to multiply the fun of the play.

Then, the playback unit 310 bypasses the video signal V directly to the display unit 330 and outputs the remaining third signal S3 and the fourth signal S4 to the demultiplexer 320. .

The demultiplexer 320 separates the first audio signal L and the second audio signal R from the third signal S3, and outputs the first audio signal L and the second audio signal R to the display unit 330, and the fourth signal S4. The toy driving signal T and the toy control signal C are separated from each other, and the frequency is again modulated and transmitted to the toy driving unit 340 in the form of a radio wave.
