Method and device for channel coding/decoding of a high-definition digital television signal broadcast by satellite

摘要: The invention relates to a method of channel coding/decoding high-definition digital television signal and the corresponding device. On coding, source is subjected frame component formation (1000) followed by error-protection coding specific modulation for each (1001) in order obtain coded components. Transmission multiplexing frames with throughput then performed at step (1002) complete broadcasting (1003). decoding, received are demodulation decoding (2000) decoded components, determination quality measurement least one significant parameter (2001) Discrimination components (2002) comparison measured threshold, so as allow use Application transmission satellite televsion signals.
