发明名称 RECEIVER AND TRANSMISSION SYSTEM
摘要 <P>PROBLEM TO BE SOLVED: To provide a receiver capable of processing a distribution request from a request source so that the content request source can receive content distribution without differentiating a communication network of the Internet from a transmission path of digital broadcasting, and to provide a transmission system. <P>SOLUTION: Upon receiving a distribution request, a multicast managing part 101 of an advanced BS receiver 200 specifies a service ID by referring to an address map table for associating information such as a destination address and a transmission source address for specifying an IP packet including content with the service ID for identifying a content download service. A front end control part 102 specifies a carrier frequency of a signal for transmitting a desired IP packet from the service ID with reference to an NIT (Network Information Table). The advanced BS receiver 200 demodulates the signal of the carrier frequency and transmits the IP packet to applications 301 to 303 of the request side. <P>COPYRIGHT: (C)2009,JPO&INPIT
