| Abstract | This paper proposes a novel joint source-channel adaptive scheme that integrates the authentication into source and channel coding components to achieve 100% effective verification probability and an optimal end-to-end video quality. By jointly considering source coding and channel conditions with authentication, the proposed layered framework is able to minimize end-to-end quality degradation incurred by both wireless channel noise and authentication failure. In particular, the competing requirements of high verification probability and low authentication overhead are concurrently satisfied by elegant design of hash appending with efficient adaptation to H.264 source coding and channel conditions. A joint source-channel-authentication rate allocation scheme is then developed to achieve optimal end-to-end video quality. Experiment results on H.264 video sequences confirm the efficacy of this joint adaptive scheme and demonstrate that it indeed outperforms the state-of-the-art graph based authentication algorithms. |

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.
