Multimedia bidirectional broadcast system

Abstract

Abstract A multimedia bidirectional broadcast system including a broadcast station (115) and subscriber terminals (116). The broadcast station (115) includes a main control unit (106) having therein a data base control table (134) in which pro­ gram and commercial down load sequences are recorded depending on a setting effected by a subscriber, a motion picture pro­ gram data base (102), a commercial data base (131), a program transmitter (103) for effecting accesses and transmissions of transmission programs onto transmission lines based on the setting of the main control unit (106), a commercial transmit­ ter (132) for accessing the commercial data base (131) and for transmitting content thereof based on the setting of the main control unit (106), an image encoder (107) for achieving a bandwidth compression on a video signal, a cell assembler (108) 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 (109) for delivering the cell to a subscriber system (116) associated therewith. Each of the subscriber systems (116) includes a network terminal (111), a terminal control unit (113), a decoder (112) to de­ code the compressed video signal, and a television monitor (114).
