Image decoding device |
摘要 |
An image decoding device for processing an input bit stream containing encoded data obtained by encoding a moving picture using intra-frame prediction, includes a stream divider configured to divide the input bit stream into a plurality of sub-streams, and a plurality of image decoders each configured to decode the corresponding one of the plurality of sub-streams, thereby outputting images. The stream divider divides the input bit stream so that the plurality of sub-streams each contain the encoded data corresponding to one or more prediction units, where macroblocks of the moving picture each include a plurality of the prediction units for the intra-frame prediction. |

1. An image decoding device for processing an input bit stream containing encoded data obtained by encoding a moving picture using intra-frame prediction, where each of the macroblocks of the moving picture includes a plurality of prediction units for the intra-frame prediction, the image decoding device comprising:
a stream divider configured to divide the input bit stream into a plurality of sub-streams; and a plurality of image decoders each configured to decode the corresponding one of the plurality of sub-streams, thereby outputting images, wherein the stream divider divides the encoded data corresponding to one of the macroblocks into groups each made up of at least one of the prediction units and outputs the sub-streams so that the groups are included in different ones of the sub-streams, each of the sub-streams includes prediction units from different macroblocks. |
