Abstract | ISO/IEC 11172 sets the bases for coding video sequences under the constraints of keeping compatibility between distinct platforms, achieving highest compression rate and decoded picture quality. Programmers feel free to rewrite the algorithms in order to improve either compression rate, or quality, or even processing time. So, once expected compression rate and minimum picture quality are fixed, programming optimization can be applied to speed up the code execution. Nevertheless, this is not a highly optimized operation on multithread, multiprocessor systems. When dealing with these platforms, programmers are able to distribute work among several processors by setting up a number of mutually independent threads. This way, code performance is heavily increased. Some methods for accelerating as much as possible the coding process with full compatibility with the standard and no quality loss are discussed. In addition, the coding system is part of a multimedia environment dealing with sequences stored in a database Organization of the whole project and communication within it is also discussed. |

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.
