摘要：
A video coding process that includes defining a context derivation neighborhood for one of a plurality of transform coefficients based on a transform coefficient scan order. The process also includes determining a context for the one of the plurality of transform coefficients based on the context derivation neighborhood. The process also includes coding the one of the plurality of transform coefficients based on the determined context.
