摘要
In one embodiment, a method for encoding video data is provided that includes receiving a transform unit comprising a two-dimensional array of transform coefficients and processing the transform coefficients of the two-dimensional array along a single-level scan order. The processing includes selecting, for each non-zero transform coefficient along the single-level scan order, one or more context models for encoding an absolute level of the non-zero transform coefficient, where the selecting is based on one or more transform coefficients previously encoded along the single-level scan order.
