Abstract:
1. A computer program recorded on a computer readable recordable medium for performing an encoding process, comprising the steps of: calculating, for a video buffer in a virtual system target decoder model for decoding re-encoded encoded streams, a first bit storage quantity which should be when input of a first picture of a first encoded stream ending with the first picture to the video buffer ends; calculating, based on the first bit storage quantity, a second bit storage quantity the video buffer in the virtual system target decoder should have for starting, according to the virtual system target model, decoding of a second picture of a second encoded stream concatenated to the end of the first picture and beginning with the second picture; re-encoding the second encoded stream based on the second bit storage quantity; and generating, based on the first bit storage quantity, a multiplexed stream including the re-encoded second encoded stream.
