Optimal GOP Size of H.264/AVC Temporal Scalable Coding

Part of the Smart Innovation, Systems and Technologies book series (SIST, volume 21)

Abstract

Scalable video coding (SVC) encodes image sequences into a single bit stream that can be adapted to various network and terminal capabilities. The H.264/AVC standard includes three kinds of video scalability, spatial scalability, quality scalability, and temporal scalability that renders different frame rates from coded bit streams. The set of pictures from one temporal base layer to the next is referred to as a group of pictures (GOP). In this paper, we investigate the GOP size that achieves the best rate-distortion performance. The factors that affect the optimal GOP size, such as video characteristics and quantization parameter (QP), are explored as well.
