| Abstract | In this paper a video watermarking scheme is presented, that is designed for the future digital cinema format, as it will be used on large projector screens in theatres. The watermark is designed such that it has minimal impact on the video quality, but still is detectable after capture with a handheld camera and conversion to, for instance, VHS, CD-Video or DVD format. In order to achieve the severe requirements, concerning visibility and robustness, the proposed watermarking system only exploits the temporal axis. A watermark is inserted by changing the mean of the luminance values of a frame according to the samples of the watermark. Watermark detection is performed by correlating the watermark sequence with extracted mean luminance values of a sequence of frames. A demonstrator, implementing the proposed algorithm, has been built which shows the aforementioned requirements can be met with the proposed scheme. |

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.
