Extension of H. 264: scalable video coding research and analysis
H.264扩展：分级编码技术研究与分析

The background and technique characteristics of scalable video coding (SVC) were introduced in detail. The motion compensated temporal filtering (MCTF) was compared with hierarchical B pictures by simulation experiments. The spatial inter-layer prediction technique was also simulated and analyzed. The simulation results indicate that the coding efficiency of MCTF is a little superior to hierarchical B pictures. Spatial inter-layer prediction improves coding efficiency while increasing computation complexity significantly so that fast decision of whether doing inter-layer prediction is an effective method to decrease the computation complexity.
