RUN-MODE BASED COEFFICIENT CODING FOR VIDEO CODING |
摘要 |
A video coding device is configured to code coefficients of residual blocks of video data. When a coefficient of a transform unit of video data has a scan order value that is less than a threshold and when the coefficient is the last significant coefficient in a scan order in the transform unit, the video coding device may execute a function to determine a mapping between data for the coefficient and a codeword index value, and code the data for the coefficient using a codeword associated with the codeword index value. The video coding device may comprise a video encoder or a video decoder, in some examples.
