Abstract
Generating a reconstructed may include reading a binary codeword corresponding to a transform coefficient for a sub-block of a transform unit, the transform coefficient having a quantized value, identifying a value of a parameter variable as zero in response to a determination that the transform coefficient is a first transform coefficient for the sub-block, and otherwise as an updated parameter variable value, converting the binary codeword into a symbol based on the value of the parameter variable, determining the absolute value of the transform coefficient corresponding to the symbol, wherein the quantized value for the transform coefficient is equal to or greater than a threshold value, by adding the threshold value to the symbol, including the transform coefficient in the sub-block of the transform unit, and generating a portion of the reconstructed frame based on the transform unit.
