| Abstract | The Personal Presence System (PPS) is an experimental prototype platform to support advanced Broadband applications including multimedia conferencing and distance learning. The PPS supports user presentation control of advanced network elements (multimedia bridges). The multimedia bridges are shared network resources which are designed for deployment in proximity to other switching and transcoding resources. The multimedia bridge provides for a single point of contact for each user so that only one combined video stream is received, thereby minimizing access bandwidth. This architecture solves the N squared transmission problem of multipoint video conferencing and allows customer premises terminal equipment to be much simpler and less expensive than high end desktop workstations. A conventional television with a set-top box may also be used as the terminal equipment for a multiparty multimedia teleconference, enabling universal video teleconferencing.The PPS provides each user with flexible presentation control of a feature-rich video bridge. Each user is able to control and customize the position, magnification and size of the video objects that they choose to receive. During the life time of a PPS session, a user can choose to receive new video objects and change how the objects are presented. In addition to supporting these basic video display capabilities, the PPS also supports advanced features such as object extraction from it's background and multimedia object associations. Multimedia associations allow a user to group together video objects into a meta-object for operations such as scaling, panning, and moving. A user can also control which other users in a session can receive the information that they are providing.This paper is a companion to another paper in this proceedings: “The Personal Presence System—Hardware Architecture” which describes the advanced video bridge experimental prototype hardware that enables this service. |

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.
