Abstract

The video coding standards are developed to satisfy the requirements of different applications for various purposes, higher coding efficiency, better picture quality, and more error robustness. The new international video coding standard H.264/AVC aims at having significant improvements in coding efficiency, and error robustness in comparison with the previous standards. Most of the video compression algorithms are designed based on the H.264/AVC. In this paper, the video encryption techniques of H.264/AVC are analyzed. Performance analysis of the three algorithms namely Selective, Layered and NaEF;ve is reported and its strength is discussed.
