Inventor: FLORENCIO DINEI A
IPC: H04N7/30
Filed: 2000-07-10
Abstract: PROBLEM TO BE SOLVED: To easily and efficiently execute variable length encoding compression by permitting at least one symbol value in the symbol values of whole groups to correspond to a plurality of different code words in a code book and permitting each code word to include at least one redundant bit. SOLUTION: After a pointer is initialized, a first symbol S1 in present three symbol links (S1, S2 and S3) is encoded to be the first three bits (c1, c2 and c3) in a six-bit code link. The pointer is carried and the second symbol S2 is encoded to be the final three bits (c4, c5 and c6). The pointer is carried again.
