| Abstract | The proposed scheme of this paper is embedding watermark into intra frame (I-frame). The most challenge of watermark that embedded into intra frame is the selection of intra prediction might be changed. In the research, different AC coefficient gets different effect when the selection of intra prediction was changed in another compression course. Therefore, it's necessary that finding what AC coefficients can be embedded watermark to avoid the quality of video might be too much lower and the watermark might be lost in another compression procedure. The proposed scheme provides a method that can endure the change of intra prediction. This scheme would against the losing of compression has be proved in accordance with the experiment results. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
