Abstract
An apparatus and method are disclosed for converting an input data character stream into a variable length encoded data stream and encoding the variable length encoded date stream according to byte length. A 2 byte length is encoded by 2 bits having the values "00". Encoded lengths of 3 and 4 bytes are represented respectively by 2 bits having the values "01" and "10". Byte lengths of 5 to 7 are represented by 4 bits "1100" to "1110" and so on to thereby enable an efficient procedure for encoding the length of a bit string during compression.
