<P>PROBLEM TO BE SOLVED: To provide an apparatus capable of performing demodulation and decoding of video signals coded in different standard formats in the field of digital signal processing. <P>SOLUTION: An adaptive receiver includes an adaptive decoder 12 for providing decoded output data from a video signal encoded for satellite, terrestrial or cable transmission. The apparatus includes adaptive decoders 50 and 60 for providing a first decoded output as a function of a code rate selected from a plurality of code rates. The apparatus also includes adaptive deinterleavers 80, 85, and 90 for deinterleaving the first decoded output in accordance with a deinterleaving function selected from a plurality of deinterleaving functions. In addition, the apparatus includes an output signal processor 125 for processing the deinterleaved output data to provide the decoded output data. A demodulator includes an adaptive error decoder 110 for detecting and correcting errors in the deinterleaved output. <P>COPYRIGHT: (C)2012,JPO&INPIT |
