ENCODING METHOD AND ENCODER

摘要

PROBLEM TO BE SOLVED: To solve the problems of pseudo synchronization and out of synchronization caused by erroneous detection of a synchronization code in an encoder.

SOLUTION: The encoder has a multiplexer 111 for multiplexing a plurality kinds of variable length codes obtained by compressing and coding an input image signal to generate a multiplexed code string 201; and an output encoder 200 for assembling the input string 201 into an output code string 205. In the encoder 200, a synchronization code is inserted into any one of a plurality of periodically predetermined synchronization code insert positions in the code string 205 according to a synchronization code insert request signal 203, and a stuffing bit is inserted into a position immediately before any one of the plurality of periodically predetermined synchronization code insert positions in the code string 205.
