Abstract
A picture data processor, a picture data decoder and a picture data encoder, and methods thereof, are capable of surely decoding and reencoding inputted coded data without delaying. Coded data D1 in order of encoding which is generated by encoding original picture data in order of display, for each prescribed data unit by a prescribed coding type I, P or B and in order of prescribed encoding, is decoded in order of this encoding. The decoded picture data D110 is outputted in order of decoding to be reencoded in order of decoding. And the reencoded data is outputted in order of encoding. Thereby, the inputted coded data D1 can be surely decoded and reencoded without delaying.
