Image display apparatus control system and image display system control method

摘要

This invention discloses an arrangement which simplifies connection between a terminal (2) for outputting at least a pair of video and acoustic signals, and a display (1) for receiving the signals from the terminal and displaying a corresponding image. A terminal modem (203) comprises a multiplexer (323) for time division multiplexing video and acoustic signals, and input/output driver circuit (320) for outputting the multiplexed signal. A display modem (103) comprises an input/output driver circuit (310) for inputting the multiplexed signal output from the terminal, and a demultiplexer (313) for demultiplexing the input multiplexed signal into corresponding video and acoustic signals. The display can be connected to an optional device, and the optional device is also controlled by the terminal.
