Abstract
In a TS information sharing system, digital broadcast receivers and a digital-broadcast-compliant TV receive TS information separately and may transfer the received TS information to each other in a peer-to-peer manner or may transfer and store the received TS information into a server. Thus, the digital broadcast receivers and the digital-broadcast-compliant TV can retrieve, from the server, TS information that the digital broadcast receivers and/or the digital-broadcast-compliant TV have not yet received. The invention can be applied to a receiver for receiving terrestrial digital broadcasts.
