Error correction encoding and decoding methods and apparatuses for DVI audio data

摘要

An error-correction coding method and an error-correction decoding method utilize error detection and error correction for an audio signal when a video signal and the audio signal are multiplexed and transmitted by a DVI. After an error correction code is added to each sample (sample data unit) of the digital audio signal, n continuous (n: integer equal to or larger than 2) pieces of the samples (sample data units) of the digital audio signal, to which error correction codes are added, are interleaved to generate a coded audio signal.
