Abstract
Erasure information associated with a received group of encoded and interleaved data in a digital video broadcasting system is stored in a much compacted form. An erasure flag and an address of a last byte associated with the received group of encoded and interleaved data (a record) encapsulated in an MPE-FEC column will be stored in an erasure table. All bytes in the column preceding the last byte of the record will have the same erasure flag as the last byte. Erasure information deinterleaverreads out the content of the erasure table (i.e., the erasure information) in a de-interleaving fashion; and the de-interleaved erasure informationare then applied with the de-interleaved coded signalsto an FEC decoderto enhance the FEC decoding performance.
