| Abstract | Several multimedia applications should run over heterogeneous networks, which are simultaneously composed by devices with different requirements of computational capability and/or communication bandwidth. In order to provide more flexibility modern encoders propose different solutions of scalable video encoding. A scalable video stream is composed by a base layer (responsible by the minimum video requirements) and several enhancement layers (each one enhances the video characteristics). During the last years several specifications of scalable video encoders were introduced. Recently MPEG and ITU-T published SVC standard as the ultimated solution to include scalable funcionality on H.264. However the whole implementation of a SVC encoder demands large computational resources and memory size. The current work presents a detailed analysis of SVC technology and its internal modules. Additionally we propose a refined architecture aiming a tradeoff among low latency time and good encoding efficiency. Comparison results indicate it as a fast and low complexity solution with small video quality loss. |

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.
