A method for padding, filtering, denoising, image enhancing and increased time-frequency acquisition is described for digitized data of a data set where unknown data is estimated using real data by adding unknown data points in a manner that the padding routine can estimate the interior data set including known and unknown data to a given accuracy on the known data points. The method also provides filtering using non-interpolating, well-tempered distributed approximating functional (NIDAF)-low-band-pass filters. The method also provides for symmetric and/or anti-symmetric extension of the data set so that the data set may be better refined and can be filtered by Fourier and other type of low frequency or harmonic filters.

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.
