SCALABLE TRANSMITTING/RECEIVING APPARATUS AND METHOD FOR IMPROVING AVAILABILITY OF BROADCASTING SERVICE |
摘要 |
<p>Provided is a scalable transmitting/receiving apparatus and method for improving availability of a broadcasting service, which can allow a reception party to select an optimum video according to an attenuation degree of a broadcasting signal by scalably encoding video data and transmitting it by a different transmission scheme for each layer. The scalable transmitting apparatus for improving availability of a broadcasting service includes: a scalable video encoder for scalably encoding video data to generate scalable video elementary streams having logical layers; a multiplexer for multiplexing the multiple scalable video elementary stream, a compressed audio elementary stream, and program specification information to generate a transport stream; and a scalable transmitter for separating the transport stream into multiple TS packet streams according to pre-given priority information, and transmitting the packet streams by a different transmission scheme for each layer. down-sampler</p> |
