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.
