Different video watermarking techniques and relative study with reference to H.264/AVC

Due to the rapid growth in information transmission technology, the technology to protect data from unauthorized users. Data could plagiarized, modified, deleted etc without proper authentication and authorization. The main technique used for protection of academic rights and copyright security is digital watermarking. Digital watermarking can be applied to media like text, audio, image, video etc. There is a growing importance in authentication and protected copyright for Digital video streams. H.264 is a next-generation video compression format. H.264/Advanced Video Codec (AVC) is significant regarding smaller bandwidth, better quality and network friendliness. In this paper a analysis was done on the basis of computational complexity and robustness of different watermarking techniques applicable for H.264.
