摘要： Reception processing of broadcast content, in transmission of which an IP system is employed, is performed. An SDPT, in a header extension part of which service identification information and an SDP are arranged, in an SSC is transmitted from a broadcasting station. On a reception side, it becomes possible to acquire an intended SDPT from signaling information SSC easily at high speed by performing section filtering processing with respect to a received transport stream. Then, it is possible to access a stream of an intended channel at high speed based on an IP address and a port number described in an SDP stored in a header extension part of the acquired SDPT.
