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.
Claims20
A system comprising:
- a receiver configured to receive a bit stream including a coded representation of a picture,
- wherein the picture includes a first sub-picture including a first set of non-overlapping regions,
- wherein the picture includes a second sub-picture including a second set of non-overlapping regions,
- wherein the first sub-picture is a left adjacent neighbor of the second sub-picture, and
- wherein data for the first set of non-overlapping regions in the bit stream immediately precedes data for the second set of non-overlapping regions in the bit stream;
- and
- one or more processors coupled to the receiver and configured to:
- decode the data for the first set of non-overlapping regions from the bit stream;
- and
- decode the data for the second set of non-overlapping regions from the bit stream.

A system comprising:
- a memory configured to store uncompressed data for a picture,
- wherein the picture includes a first sub-picture including a first set of non-overlapping regions,
- wherein the picture includes a second sub-picture including a second set of non-overlapping regions, and
- wherein the first sub-picture is a left adjacent neighbor of the second sub-picture;
- and
