| Abstract | In this paper, TA-ARQ (Time-constrained Aggregated Automatic Repeat-reQuest) with an adaptive rate control for SVC streaming based on HDP transport protocol is proposed. To meet the requirement of terminal equipment in the heterogeneous network environments, we consider SVC for different applications. Selected NALUs (Network Abstraction Layer Units) are sent according to the quality estimation of scalable video coding in the server. Moreover, a retransmission mechanism is adopted to reduce loading of the aggregated ARQ retransmissions in multimedia networks and enhance the quality of video streaming. Based on the evaluation of NALU quantity and display order, the priority of each unit is determined. In transmission of SVC sequences, the server can extract different transmission packets, especially for retransmitting lost data. The experimental results show that the bandwidth utilization ratio of the proposed scheme can be up to 91.25% compared with decoding-order-based decision when the theoretical bandwidth is 5 Mbps. In advance, the proposed scheme with TA-ARQ can have quality gain about 0.4 dB in the unicast receiver. |

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.
