摘要

提出了一种基于H.264/AVC的细粒度可扩展性(FGS)算法。该算法包含在H.264/AVC可扩展的工作草案2中。以循环方式编码块系数将“高值”位放在比特流的前面。如果位流被截断，则更有可能保留较高值的位。通过以这种方式排列比特流，相对于非周期编码，可实现高达0.5 dB的PSNR增益，这取决于序列和比特流截断点。

Fine-grained scalability for H.264/AVC

An algorithm for fine-grained scalability (FGS) in H.264/AVC is presented. This algorithm is included in Working Draft 2 of the H.264/AVC scalable extension. Encoding block coefficients in a cyclical manner places “higher-value” bits earlier in the bit stream. If the bit stream is truncated, higher-value bits are therefore more likely to be retained. By arranging the bit stream in such a manner, a PSNR gain of up to 0.5 dB can be achieved versus non-cyclical coding, depending upon the sequence and bit stream truncation point.
