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;
- and
- one or more processors configured to:
- determine a first position for a single non-overlapping region in the picture based on a first scan order, wherein the picture includes:
- a first sub-picture having a first set of non-overlapping regions;
- and
- a second sub-picture having a second set of non-overlapping regions;
- determine that the first sub-picture contains the single non-overlapping region;
- and
- determine a second position of the single non-overlapping region in the first sub-picture based on the first position and based on a second scan order,
- wherein the second scan order is based on a position of the single non-overlapping region in the first sub-picture.
A method comprising:
- determining a first position for a single non-overlapping region in a picture based on a first scan order, wherein the picture includes:
- a first sub-picture having a first set of non-overlapping regions;
- and
- a second sub-picture having a second set of non-overlapping regions;
- determining that the first sub-picture contains the single non-overlapping region;
- and
- determining a second position of the single non-overlapping region in the first sub-picture based on the first position and based on a second scan order,
- wherein the second scan order is based on a position of the single non-overlapping region in the first sub-picture.
A non-transitory computer-readable medium having executable instructions stored thereon, configured to be executable by one or more processors circuitry for causing the one or more processors to:
- determine a first position for a single non-overlapping region in a picture based on a first scan order, wherein the picture includes:
- a first sub-picture having a first set of non-overlapping regions;
- and
- a second sub-picture having a second set of non-overlapping regions;
- determine that the first sub-picture contains the single non-overlapping region;
- and
- determine a second position of the single non-overlapping region in the first sub-picture based on the first position and based on a second scan order,
- wherein the second scan order is based on a position of the single non-overlapping region in the first sub-picture.
