| Abstract | To solve recent pressing issues regarding satisfying numerous video codec standards and supporting “full-high-definition” (full-HD) (i.e., 1920 pixels by 1080 lines) video on different consumer devices, a multi-standard CODEC IP based on a heterogeneous multiprocessor architecture was developed. To achieve satisfactory performance with low power consumption, operation-specific processors were designed in regards to two types of processing: stream processing and pixel processing. The CODEC uses effectively several dedicated circuits for functions which are unsuitable for those processors. To design the CODEC, we developed a C-language model to check that the architecture worked correctly. The model was also used as a reference for verifying the RTL model. The CODEC can process full-HD videos formatted in H.264, MPEG-2, MPEG-4, and VC-1 at an operating frequency of 162 MHz. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
