Abstract
An apparatus and method for processing a stream compressed and encoded with a variable length code (VLC) in a predetermined unit by detecting an error flag that has been set. The flag corresponds to a position of an error when the error is contained in the stream. Adding information representing an end of the VLC, based on the error flag, to the position corresponding to the error flag in a string of the VLC containing the error flag. Thus, the VLC after the error flag can be discarded. Additionally, an apparatus and method for processing a stream encoded with a VLC by detecting a code symbol that does not match a parameter representing the VLC from the VLC stream. Correcting the stream based on the detected result, and designating the start of the next process after the detected result has been obtained. Thus, even if a stream containing an irregular VLC is input, the apparatus can be operated in a stable mode.
