| Abstract | Heterogeneous QoS video broadcast over wireless network is a challenging problem, where the demand for better video quality needs to be reconciled with different display size, channel condition and QoS requirements. In this paper, we present a framework for broadcasting scalable video to heterogeneous mobile users with diverse display devices and different channel conditions, which includes joint spatial-temporal layered video and Fountain coding optimization. First, we develop an elastic rate video adaptation method so as to serve mobile users with heterogeneous QoS requirements, which includes a hybrid temporal-spatial quality metric. Joint Fountain coding protection is introduced so as to provide adaptive and reliable video streams. Second, we use dynamic programming approach to obtain optimal video layer structure, so as to achieve maximum broadcasting utility. The objective is to achieve maximum overall receiving quality of the heterogeneous QoS users. Experimental results demonstrate the effectiveness of the solution. |

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.
