Abstract:
A stream processing apparatus comprising:parsing means for parsing a syntax of a source encoded stream to extract a plurality of coding parameters from said source encoded stream; detecting means for detecting an error macroblock having a syntax error in said source. encoded stream in accordance with a result of a parsing process performed by said parsing means; variable-length-decoding means for performing a variable-length-decoding process on said source encoded stream to generate a variable-length-decoded stream; generating means for generating a predetermined macroblock having a correct syntax which conforms to a motion picture image coding experts group (MPEG) standard; and substituting means for substituting said predetermined macroblock from said generating means for said error macroblock of said variable-length-decoded stream, whereby said substituting means calculates a number of macroblocks which can not be correctly processed due to the syntax error in accordance with the number of macroblocks which have been variable-length decoded and the total number of macroblocks of a respective slice layer having said error macroblock.
