Digital broadcast receiver and digital broadcast receiving method

摘要

A digital broadcast receiver capable of adequately receiving a higher-level layer service along with a lower-level layer service even if the reception CNR degrades. A demodulation decoding section ( 2 ) of the receiver judges on the basis of transport and multiplexing configuration control information whether the TS packet allocated to each slot is adapted to a higher-level layer service or a lower-level layer service and informs a code writing section ( 3 ) of the result. The code writing section ( 3 ) writes, in each TS packet, a layer identification code for judging whether the TS packet is adapted to a higher-level layer service or a lower-layer service and synthesizes a resultant TS packet. A stream separating section ( 4 ) reads the layer identification code along with the PID in the packet header included in the TS packet and finds and extracts a desired TS packet.
