Abstract
In one embodiment, a method for encoding video data is provided that includes receiving an array of transform coefficients corresponding to a luma component or a chroma component of the video data. The method further includes encoding a significance map for the array, where the encoding includes selecting, using a shared context derivation process that applies to both the luma component and the chroma component, context models for encoding significance values in the significance map.
