Abstract: A program information transport apparatus comprises a update unit for accepting a request for a change in either one of program information and transmission control information stored in a memory, and for updating the contents of the memory according to the change at predetermined update times to update the program information. An information management unit can acquire the program information from the memory and then furnish the acquired program information at predetermined transport times to transport the program information. A transport unit then transports the program information from the information management unit to receivers.

Abstract: The program guide data collection and delivery device for collecting and delivering program guide data of a plurality of broadcasting stations respectively broadcasting their own programs collects own-station EPG data from a plurality of program guide data transmitting devices respectively corresponding to each of the broadcasting stations, and delivers all-station EPG data to a plurality of program guide data providing devices. By this configuration, the rate of inter-access among the stations is not made high regardless of a frequent modification of EPG data of the broadcasting stations, and the program guide viewers of one station can be provided with the latest EPG data of other stations without changing the individual system configuration, even when there is an increase in the number of broadcasting stations within the whole system.
