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 transmission multiple structure 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-level 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. |
