SYSTEM AND METHOD FOR RATE-DISTORTION OPTIMIZED DATA PARTITIONING FOR VIDEO CODING USING BACKWARD ADAPTATION |
摘要 |
<p>A system and method are disclosed that provide a simple and efficient layered video coding technique using a backward adaptive rate-distortion optimized data partitioning (RD-DP) of DCT coefficients. The video coding system may include an rate-distortion optimized data partitioning encoder and decoder. The RD-DP encoder adapts the partition point block-by-block which greatly improves the coding efficiency of the base layer bit stream without explicit transmission thereby saving the bandwidth significantly. The RD-DP decoder can also find the partition location in backward-fashion from the decoded data.</p> |
