| Abstract | Tele-immersion is emerging as a new medium that creates 3D photorealistic, immersive, and interactive experience between geographically dispersed users. However, most existing tele-immersive systems can only support two-way collaboration. In this paper we propose a multi-layer framework and a new data dissemination protocol to support multi-site collaboration. The problem context is unique as multiple remote sites participate in an interactive tele-immersive session, where each site has multiple correlated 3D video streams to send (later referred as multi-stream/multi-site environments). The key challenge is to disseminate such large number of 3D live video streams among these sites subject to the bandwidth and latency constraints while satisfying QoS guarantees in visual quality. Among our findings is that the simple randomized algorithm outperforms many other static algorithms in the unique context. Moreover, the streams generated from one site have high semantic correlation, because often cameras at one site are shooting the same scene, only from different angles. We exploit the stream correlation in the multicast protocol to minimize the level of 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.
