ABSTRACT:
A multimedia bidirectional broadcast system including a broadcast station and subscriber terminals. The broadcast station includes a main control unit having therein a data base control table in which program and commerical down load sequences are recorded depending on a setting effected by a subscriber, a motion picture program data base, a commerical data base, a program transmitter for effecting accesses and transmissions of transmission programs onto transmission lines based on the setting of the main control unit, a commercial transmitter for accessing the commerical data base and for transmitting content thereof based on the setting of the main control unit, an image encoder for achieving a bandwidth compression on a video signal, a cell assembler for processing data to be transmitted onto a broadband transmission line so as to generate a cell of the data, and an asynchronous transfer mode exchange for delivering the cell to a subscriber system associated therewith. Each of the subscriber systems includes a network terminal, a terminal control unit, a decoder to decode the compressed video signal, and a television monitor.
