Document Type and Number:
Japanese Patent JP2002533975
Kind Code:
A
Abstract:
An encoding device encodes a stream of databits of a binary source signal into a stream of databits of a binary channel signal, wherein the stream of databits of the source signal is divided into n-bit source words, which device includes converting apparatus to convert the n-bit source words into corresponding m-bit channel words in accordance with a conversion of the parity preserve type, where m and n are integers, with m>n. The device further includes control apparatus for carrying out DC-control on the binary channel signal by introducing a freedom of choice in the source-to-channel conversion. A decoding device decodes the channel signal obtained from the encoding device.
