| Abstract | With the advent of low-cost capturing hardware, omnidirectional or panoramic video is likely to become a more popular delivery format for video content in the near future. Besides the inherent advantage of being able to capture anything within a scene without intervention from a director or camera operator, the format also increases the interactivity for the end-user and may result in a more immersive experience. To stream this kind of content to a wide range of end-users, a web-based delivery platform is clearly preferred. Unfortunately, a lack of uniform codec and streaming container format support hinders practical deployment, especially for live content distribution. In this paper, a solution is proposed that overcomes these issues for most browsers currently in use by desktop computers. It consists of a back-end module that encodes and encapsulates content into a WebM compliant streamable format in real-time, which is subsequently decoded by the built-in browser decoders and displayed through an HTML5 'canvas' element - either through a planar projection in 2D or through a 3D spherical texture transformation in WebGL. The proposed solution has been deployed on an existing CDN and tested for scalability in the context of a day-long event with omni-directional webcasts. |

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.
