PROBLEM TO BE SOLVED: To minimize image degradation generated by re-encoding, and reduce a time used for re-encoding processing.;SOLUTION: In a transcoding method where a digital signal is received to extract parameter data, the digital video data are decoded using the parameter data, the parameter data and the digital video data are sent to an encoding part, and the encoding part uses the parameter data to encode the digital video data, the parameter data are transmitted to the encoding part before the digital video data related to the parameter data are transmitted to the encoding part.;COPYRIGHT: (C)2007,JPO&INPIT
