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 deinterleaver 524 reads out the content of the erasure table (i.e., the erasure information) in a de-interleaving fashion; and the de-interleaved erasure information 525 are then applied with the de-interleaved coded signals 511 to an FEC decoder 526 to enhance the FEC decoding performance.
