| Abstract | The ability to deliver digital video over wireless networks is an enabling technology for many useful applications, ranging from home entertainment and security monitoring to enterprise messaging and military reconnaissance, and thus represents the holy grail of wireless technology development. We describe a wireless video delivery system, WiVision, which uses IEEE 802.11 wireless LANs as the last mile for both real-time video distribution and on-demand video playback. WiVision can air both live events, such as on-campus seminars and sports activities, and prestored video streams, such as course lectures and financial analysis sessions, to mobile users, who can tune in to selected channels of their choice from their laptops or PDAs. An innovative feature of WiVision is the support for random video access based on keyword-search, where keywords are extracted from the closed-caption text embedded in TV programs. In addition, WiVision is able to broadcast video streams on the wireless link while seamlessly working with commercially available media players. The paper presents the implementation details of the real-time acquisition and network transport components of a fully operational WiVision prototype, and the results of a performance evaluation study on that prototype. |

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.
