PROBLEM TO BE SOLVED: To provide an apparatus capable of demodulating and decoding video signals encoded in different various standard formats, in the field of digital signal processing. SOLUTION: An adaptive receiver includes an adaptive decoder for providing decoded output data from a video signal encoded for satellite, terrestrial or cable transmission. The apparatus includes an adaptive decoder for providing a first decoded output as a function of a code rate selected from a plurality of code rates. The apparatus also includes an adaptive deinterleaver for deinterleaving the first decoded output, in accordance with deinterleaving function, selected from among a plurality of deinterleaving functions. In addition, the apparatus includes an output signal processor for processing the deinterleaved output data to provide the decoded output data. The demodulator also incorporates an adaptive error decoder for detecting and correcting errors in the deinterleaved output. COPYRIGHT: (C)2007,JPO&INPIT |
