Embodiment Construction

[0033] In the following description, some example embodiments are described with reference to the H.264 standard for video coding and / or the developing HEVC standard. Those skilled in the art should understand that the present application is not limited to H.264 or HEVC, but is applicable to other video coding / decoding standards, including possible future standards, multi-view coding standards, scalable video coding standards, and reconfigurable The configured video encoding standard.

[0034] In the following description, the terms frame, picture, slice, tile and rectangular slice group are used somewhat interchangeably when referring to video or images. Those skilled in the art will recognize that, in the case of the H.264 standard, a frame may contain one or more slices. It will also be recognized that, depending on the specific requirements or terminology of the applicable image or video coding standard, some encoding / decoding operations are performed on a frame-by-frame ...

Abstract

Methods of encoding and decoding for video data are describe in which significance maps are encoded and decoded using non-spatially-uniform partitioning of the map into parts, wherein the bit positions within each part are associated with a given context. Example partition sets and processes for selecting from amongst predetermined partition sets and communicating the selection to the decoder are described.

The copyright owner has no objection to the facsimile reproduction by anyone of the patent document or the patent disclosure, as published in the Patent and Trademark Office files or records, but reserves other copyright rights whatsoever. technical field [0003] The present application relates generally to data compression, and in particular to methods and apparatus for encoding and decoding significance maps of video using partition selection. Background technique [0004] Data compression occurs in numerous contexts. Data compression is very commonly used in communications and computer networking to efficiently store, transmit and reproduce information. It finds specific application in the encoding of graphics, audio and video. Video presents considerable challenges to data compression due to the large amount of data...
