Recent methods and techniques in video watermarking and their applicability to the next generation video codec

Abstract

High efficiency video coding (HEVC) is the newest video coding generation of the ITU-T and ISO/IEC, which first appeared in January 2013. It has the advantage of reducing the bit rate by as much as 50 % when compared to H.264 while maintaining the same visual quality. In the last decade, authentication and copyright protection methodologies have become one of the essential items in order to protect video contents by embedding within an efficient video codec. Thus, the objective of this paper is to revise recent developments in the area of watermarking techniques for video coding schemes and their applicability to the new Standard HEVC. The results of this study provide motivation to achieve a higher embedding capacity and higher compression performance for HEVC compared to H.264/AVC especially, for low bitrate coding.
