Modified systems for broadcasting M/H data employ two-dimensional coding of RS Frames that combines transverse RS coding with subsequent byte-error-locating block coding that generates codewords of a prescribed standard length. This prescribed standard length is chosen such that an integral number of codewords of the byte-error-locating block code fits exactly, or substantially so, into the portion of each RS Frame that is encoded in CCC for inclusion within an M/H Group. The byte-error-locating block coding is CRC coding by way of one specific example or is Reed-Solomon (LRS) forward-error-correction (FEC) coding by way of another specific example. M/H receivers are described in which codewords of this byte-error-locating block coding are decoded and used to influence the soft decisions concerning data bits. Then, these soft decisions are processed and used for locating byte errors for the transverse Reed-Solomon (TRS) codes on an individual basis. |
