Original Abstract Submitted
A video coder may be configured to code a plurality of syntax elements that indicate an absolute value of a transform coefficients in a block, wherein the plurality of syntax elements include a significance flag and four or more greater_than_N flags. The video coder may further determine first respective contexts for each syntax element in a first set of the plurality of syntax elements from respective context tables for each syntax element in the first set of the plurality of syntax elements, and determine second respective contexts for each syntax element in a second set of the plurality of syntax elements from a shared context table.
