ROBUST SIGNAL CODING |
摘要 |
<p>The present invention concerns methods and devices for coding and decoding a coded data stream as well as a signal format for a coded data stream. The coded data stream includes at least one high-level data packet having partitions of data ( 56, 62, 68 ) requiring different protection rates. Partition detectors ( 50 ) are inserted between two such partitions by a partition detector inserter, in order to provide guidance for coding the partitions with different protection rates. Information about the code rates used for the different fields is extracted by a controller on the receiving side in order to decode the partitions with the right code rate.</p> |
