Abstract:
1. An information processing apparatus for decoding comprising: an analysis means for analyzing a code stream, in which picture data is encoded, during transmission, wherein the picture data not having a portion indicating a start of a line, and the analysis means determines a head position of a line in the picture data based on analyzed sizes of video and macro block of the code stream; a dividing position determination means for calculating a number of lines in which an amount of picture data is an integral multiple of a burst boundary of a storage means, for determining a dividing position of the code stream to form plural streams in accordance with the calculated number of lines as a unit of division and for adding header information to the code stream in the unit of division, wherein the dividing position determination means determines the dividing position corresponding to the burst boundary of the storage means; a decoding means for decoding the plural streams in parallel, which are obtained by the code stream being divided at the dividing position determined by the dividing position determination means, wherein timings of start and end of each parallel decoding processing do not always correspond to one another; an acquisition means for acquiring the code stream; said storage means for storing the code stream acquired by the acquisition means, wherein the analysis means analyzes the code stream acquired by the acquisition means while storing the code stream in the storage means; a control means for supplying results of decoding processing by the decoding means to the storage means by a burst transfer to be stored therein; and an output means for reading the results of decoding processing stored by the storage means from the storage means by the burst transfer and outputting the results.
