摘要：
This disclosure relates to video coding and more particularly to techniques for performing entropy coding. According to an aspect of an invention, a parity level flag specifying a parity of a transform coefficient level at a scanning position is decoded if a value of a second absolute level greater flag is equal to a first value.
