Abstract
A method and apparatus for sub-picture based raster scanning coding order. The method includes dividing an image into even sub-pictures, and encoding parallel sub-pictures on multi-cores in raster scanning order within sub-pictures, wherein from core to core, coding of the sub-picture is independent around sub-picture boundaries, and wherein within a core, coding of a sub-picture is at least one of dependent or independent around sub-picture boundaries.
Claims5
A method for sub-picture based raster scanning coding order, comprising:
- dividing a picture into a plurality of non overlapping blocks;
- partitioning the non overlapping blocks into a plurality of sub-pictures with sub-picture boundaries;
- coding of a first of the plurality of the sub-pictures and coding of a second of the plurality of the sub-pictures such that the coding of the first sub-picture and the coding of the second sub-picture is independent around the sub-picture boundaries;
- coding of the first sub-picture and the coding of the second sub-picture in parallel;
- and
- encoding the first and second sub-pictures sequentially into a bit stream upon completion of the coding wherein each of the first and second sub-pictures is encoded in a raster scan order

A method for sub-picture based raster scanning coding order, comprising:
- providing a picture partitioned into a plurality of sub-pictures wherein each sub-picture is divided into a plurality of non overlapping blocks;
- coding of a first of the plurality of the sub-pictures and coding of a second of the plurality of the sub-pictures 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 first of sub-pictures and the second of the sub-pictures sequentially into a bit stream upon completion of the coding wherein each of the first of sub-pictures and the second of the sub-pictures is encoded in a raster scan order
