发明名称 Satellite broadcasting system capable of designating areas for broadcasting program and satellite broadcasting reception apparatus
摘要 A satellite broadcasting system is disclosed wherein, when a broadcasting program is broadcast by satellite broadcasting, each viewer can receive a different broadcasting program depending upon the district in which the viewer is present. A broadcasting program is composed of an area designation part in which a list of areas in which the broadcasting program is to be broadcast is accommodated and broadcasting contents themselves. The broadcasting program is received by a radio wave reception section. A current position acquisition section detects the current position of a receiver. The current position is compared with an area to physical district coordination table and converted into an area name by a current area detection section. If the area name outputted from the current area detection section is included in the area designation part of the broadcasting program received from the radio wave reception section, then a broadcasting propriety discrimination section outputs the contents part of the broadcasting program to are production section. Alternatively, if the area name is included in the area designation part of the broadcasting program, then the broadcasting propriety discrimination section refrains itself from outputting the contents part of the broadcasting program to the reproduction section.
