TRANSITION BETWEEN RUN AND LEVEL CODING MODES |
摘要 |
This disclosure describes techniques for coding transform coefficients for a block of video data. According to some aspects of this disclosure, a video coder (e.g., encoder, decoder) may code a first coefficient of a leaf-level unit of video data using a run encoding mode. The coder may code a second coefficient of the leaf-level unit of video data using a level encoding mode. After coding at least one coefficient using the level coding mode, the coder may use the run coding mode to code a third other coefficient of the leaf-level unit of video data. According to other aspects, an encoder may signal, to a decoder, at least one indication of a transition between level and run coding modes. According to still other aspects, a coder may automatically determine when to transition between the level and run coding modes. |
