Abstract
An arrangement including a terminal for outputting at least a pair of video and acoustic signals, and a display for receiving the signals from the terminal and displaying a corresponding image, utilizes (1) a terminal modem including a multiplexer for time division multiplexing video and acoustic signals, and an input/output driver circuit for outputting the multiplexed signal, and (2) a display modem including an input/output driver circuit for inputting the multiplexed signal output from the terminal, and a demultiplexer 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.
