CONTEXT MODELING TECHNIQUES FOR TRANSFORM COEFFICIENT LEVEL CODING

摘要

In one embodiment, there is provided a method of encoding video data comprising receiving a transform unit comprising a two-dimensional array of transform coefficients, and processing the transform coefficients of the two-dimensional array according to a single level scan order do. Processing comprises selecting, for each non-zero transform coefficient according to a single level scan order, one or more context models for encoding the absolute level of non-zero transform coefficients, Is based on one or more transform coefficients pre-encoded in a single level scan order.
