Digital broadcasting receiving apparatus, broadcasting area server, and broadcast reception system, as well as the broadcast area information generating method

摘要

In the receiving system that includes plurality of digital broadcast receiving apparatus (101), each receiving device (101) to generate a neighbor broadcast service area information, and stores therein, and transmits the broadcast area server (201). By using the close information from a plurality of the receiving device in the broadcast area server (201) (101) to generate or update the entire broadcast area information. If there is a notification of the current position from each of the receiving device (101), the current position and the broadcast area information around that, is extracted from the entire broadcast area information, and transmits it to the receiving device. In the receiving apparatus, by using the broadcast area information transmitted from the broadcast area server, it updates the broadcasting area information stored therein. Used as a representation of a polygon vertex coordinate as a broadcast area information. It can be generated broadcast area information efficiently, and less network load.
