Title:
相異なる種々のフォーマットで符号化されたビデオ信号を復号する装置
Document Type and Number:
Japanese Patent JP4578563
Kind Code:
B2
Abstract:
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 a deinterleaving function selected from 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 may also incorporate a an adaptive error decoder for detecting and correcting errors in the deinterleaved output. In addition, a signal quality detector may provide an estimate of the error in the decoded output data. The apparatus is automatically configured to be compatible with the encoded video signal format in response to the error estimate.
