Abstract: When a change in sub-channel selection is made after a mobile/handheld (M/H) Frame is begun, an M/H receiver is for some time unable to correct byte errors by transverse Reed-Solomon (TRS) decoding of turbo decoding results. Despite this, later stages of the M/H receiver are supplied data that cyclic-redundancy-check (CRC) decoding of Internet protocol (IP) packets does not find to be in error. Some of the IP packets comprise Service Map Table (SMT)-mobile/handheld (MH) data used to update SMT determining how the M/H receiver is operated. SMT-MH data that have not been subjected to TRS byte-error correction are kept from updating the SMT until those SMT-MH data are verified by later SMT-MH data subjected to TRS byte-error correction. Transmitting total number of Groups (TNOG) information for the currently received M/H Frame in all its sub-frames speeds up acquisition of Fast Information Channel updates by the M/H receiver.

Abstract: Digital television broadcasting signals employ parallel concatenated convolutional coding, commonly called “turbo coding”, to improve reception by receivers in motor vehicles. Turbo coded Reed-Solomon codewords are transversally disposed in the payload fields of encapsulating MPEG-2-compliant packets to improve the capability of the Reed-Solomon coding to overcome deep fades. Turbo codewords are transmitted more than once in so-called “staggercasting”. Reception of DTV signals is improved by combining soft decisions concerning repeated transmissions of turbo codewords before turbo decoding. Only the data components of turbo codewords are transmitted twice in “punctured” staggercasting of turbo codewords, with parity components being transmitted only once, so code rate is reduced by a smaller factor than two.
