Optimization Of The Encoding Algorithm Complexity For The H.264 Scalable Extension

Different compression and transmission systems have to be constructed for users in different conditions if they are built on the top of traditional non-scalable video encoding and decoding techniques. With the development of ubiquitous multimedia, scalable video coding techniques are desired for efficiently repurposing and transporting the video contents over heterogeneous networks/devices. The scalable extension of H.264 is the newest work of developing joint standards for ISO/IEC and ITU. Based on the newest encoding and decoding techniques, temporal, spatial and quality scalability is realized with an unified framework in H.264 scalable extension standard at the cost of significantly increasing computational complexity. It motivated us to study the optimization of the encoding algorithm for the H.264 scalability extension so as to reduce the complexity while keeping the coding efficiency of H.264 scalable extension.This thesis first analyzes the scalable mechanisms of temporal,...
