SIGNALING QUANTIZATION PARAMETER CHANGES FOR CODED UNITS IN HIGH EFFICIENCY VIDEO CODING (HEVC) |
摘要 |
<p>In one example, this disclosure describes a method of decoding video data. The method comprises receiving a coding unit (CU) of encoded video data. The CU is partitioned into a set of block-sized coded units (CUs) according to a quadtree partitioning scheme, and decoding one or more syntax elements for the CU to indicate a change in a quantization parameter for the CU relative to a predicted quantization parameter for the CU only if the CU includes any non-zero transform coefficients. The one or more syntax elements are decoded from a position within the encoded video data after an indication that the CU will include at least some non-zero transform coefficients, and before the transform coefficients for the CU.</p> |
