A DEDICATED SYSTEM FOR AUDIO AND VIDEO SIGNAL BIDIRECTIONAL COMMUNICATION

摘要

A dedicated system for the bidirectional communication of audio and video signals, connectable to a plurality of communication systems, both local and remote, and able to be interfaced to a plurality of devices for the acquisition and reproduction of video and sound signals. The system includes: an interface block (120) for communication line connection (L); a coding/decoding block (130) for data compression and expansion, such block being connectable to audio and video peripheral devices; a programmable central processing unit (100) for system control; a memory (110) for storing data and programs for the proper working of the system; and means (190) for inputting commands from the user.
