| 摘要 |
A device is disclosed for encoding a stream of databits of a binary source signal (S) into a stream of databits of a binary channel signal (C), wherein the stream of databits of the source signal is divided into n-bit source words (X1, X2), which device comprises converting means (CM) conceived to convert said n-bit source words into corresponding m-bit channel words (Y1, Y2, Y3) in accordance with a conversion of the Jacoby type, where m and n are integers, with m~n. The device further comprises control means (10) for carrying out DCcontrol of said binary channel signal by introducing a freedom of choice in the source-to-channel conversion. Furthermore, a decoding device is disclosed for decoding the channel signal obtained by means of the encoding device.
