Abstract

Official abstract text for this publication.

A broadcast and receiver system for performing content from combined A/53 and A/153 standard transmissions enabling simultaneous reception of both signal types with one device. A combination HDTV/Mobile DTV chip can be used that does not alter the legacy HDTV forward error correction (FEC) decoder and Mobile DTV standard transmissions may include extra training signals aiding the demodulation of legacy HDTV reception. Two separate Trellis decoders can be used: one for A/53 legacy HDTV decoding and the other for A/153 Mobile DTV decoding that uses a Hard Input Hard Output (HIHO) type of architecture. Separate Viterbi decoders are allocated for each block of data with a block Viterbi rotator to parse out/collect results of each Viterbi decoder. Each block has its convolutional encoder reset at the beginning. The second Trellis decoder operates serially so as not to disturb the A/53 HDTV data but could also be operated in parallel.

First claim

Opening claim text (preview).

What is claimed is: 1. An apparatus for processing a combined A/53 and A/153 standard broadcast signal, comprising: (a) a receiver with a decoder and an output, the receiver configured to receive a combined A/53 and A/153 RF signal and provide an output transport signal stream; and (b) programming executable on a processor of the decoder processing the received combined signal, the processing comprising: (i) sub-processing an A/53 signal component with a first Trellis decoder w…
