| Abstract | According to Cisco study, mobile video already makes up 50% of mobile data traffic and is expected to reach 66% in 2015. Nowadays, the video watching experience is being made more interactive to enhance the user experience. One way that users can enjoy better watching experience is to be able to switch between different perspectives in one video. Such multi-perspective events require an efficient streaming scheme that is both cost-efficient and user-friendly. Based on three popular video streaming methods (RTP/RTSP, HTTP Progressive Download and DASH), we propose three different solutions for streaming multi-perspective videos. Architectures and principles of each solution are discussed and implemented on an Android-platform-based smartphone. To compare the performance of our solutions, we design a framework for evaluation. The metrics we use to evaluate our solutions include bandwidth consumption and Quality of Service (QoS) parameters, such as switch delay and switch rendering. Our comparison shows that all three solutions can achieve acceptable performance for perspective switching. However, the DASH-based solution outperforms the remaining solutions at it provides shortest delay and seamless switching of perspectives for a given bandwidth. |

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.
