摘要 |
<p>A digitally coded signal is encoded with an error correction code and an error detection code. When the signal is decoded, the error correction code is used to correct errors. The error detection code is then used to discriminate whether the error correction process has operated properly, and if it has not operated properly then interpolation is used to avoid remaining errors. Preferably when the data is encoded the error detection code is provided before the error correction code is provided. <IMAGE></p> |
