Abstract
A picture information conversion method and apparatus in which, if the compressed picture information with a variable or non-recognized information volume is input, optimum compression processing on the compressed picture information is performed to prevent underflow and/or overflow to suppress deterioration of the picture quality. A compressed information analysis device analyzes the structure of the picture type of the GOP of the compressed picture information input to the FF buffer . A bit allocation device generates a pseudo GOP of the input compressed picture information, based on N frames stored in the FF buffer and on the analysis result information stored in the information buffer , and allocates a pre-set code volume to respective pictures of the generated GOP so that the output compressed picture information will be at a second bitrate.
