| Abstract | Due to the decoding dependency of MPEG coded frames, lots ofdependent frames are transmitted at Video Cassette Recording (VCR)operations, thus more computation resource, hard disk and networkbandwidth are consumed on streaming meida server, and higherdecoding complexity on Set-Top Box (STB). To tackle this problem,our scheme of supporting VCR functionalities with adaptive rateadjustment in streaming media server is proposed. The schemeincludes a general VCR functionalities supporting method called GVFRwhich selects frames based on Group of Pictures (GOP) and usesVariable Frame Rate (VFR). Selecting frames based on GOP canefficiently eliminate the transmission of dependent frames, and therealization of VFR leads to optional transmission rate. Then anintelligent decision mode is introduced which automatically picksthe appropriate GVFR strategies with suitable transmission ratebased on the congestion status of the link. The experimental resultsdemonstrate that GVFR can greatly decrease the transmission rate offast forward/backward, to 22\% of that of normal playback at least,and by varying GVFR strategies, VCR with optional transmission rateis achieved. |

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.
