Abstract
An example device for coding (encoding and/or decoding) video data includes a memory configured to store video data; and one or more processors implemented in circuitry and configured to: calculate a sum of absolute values of a plurality of neighboring coefficients to a current coefficient for a current block of video data; calculate a base level offset value according to at least one of a bit depth for the video data or a slice type for a slice including the current block; calculate a normalized value for the sum of absolute values using the base level offset value; and code the current coefficient using the normalized value for the sum of absolute values.
