Abstract
An apparatus for encoding variable bit length data words into constant bit length data words concatenates the variable length data words supplied at a first data rate so as to output constant length data words at a second data rate. An apparatus for decoding constant bit length data words into variable bit length data words shifts and concatenates the constant bit length data words, determines when a variable length data word is present in the concatenated data, supplies information about the number of bits in the variable length data words which is used when shifting the next constant bit length data word, and outputs variable bit length data words.
