Abstract
A community antenna broadcasting system comprises a transmitting center for broadcasting programs in physical channels, a transmission path, and one or a plurality of home terminals for receiving the programs broadcast from the transmitting center via the transmission path. The transmitting center transmits a main information which includes video and audio information for each of physical channels, and also transmits a control information which includes numbers of logical channels which are contents of the physical channels. The home terminal enters a supervision information which includes a number of a desired logical channel which corresponds to a desired program, and produces a channel selection instruction by collating the control information and the supervision information. A channel selection part is provided within the home terminal. The channel selection part receives the information via the transmission path and selects a physical channel in response to the channel selection instruction.
