Abstract:
1. A method for sub-picture based raster scanning coding order, comprising: dividing a picture into a plurality of non overlapping macroblocks; partitioning the non overlapping macroblocks into a plurality of sub-pictures with sub-picture boundaries; coding of a first of the plurality of the sub-pictures is performed on a first processing core and coding of a second of the plurality of the sub-pictures is performed on a second processing core wherein the coding of the first sub-picture and the second sub-pictures is independent around the sub-picture boundaries, and wherein the coding of the first sub-picture and the second sub-picture is performed in parallel; and encoding the plurality of sub-pictures sequentially into a bit stream upon completion of the coding wherein each of said plurality of sub-pictures is encoded in a raster scan order.
