Abstract:
There are provided a transmitting section 308 for receiving program information representative of an outline and receiving condition of a receivable program and further receiving a program on the basis of the program information, and a zone-change determining section 307 for detecting a change of the program information. The program selecting section 309 causes the transmitting section 308 to suspend program reception and to switch a communication port, on the basis of a determination of a change of program distribution area by the zone-change determining section 307. Due to this, the transmitting section 308 is allowed to continuously receive the program so far received. This, in the case a program is provided at a communication port different based on each region, makes it possible to correctly receive a program even if moving traversing a region.
