Abstract: The existing multimedia software in e-learning does not provide par excellence multimedia data service to the common user; hence e-learning services are still short of intelligence and sophisticated end user tools for visualization and retrieval. Delivery of multimedia in the presence of bandwidth constraints is one of the most important video processing problems. The work presents an innovative and complete end-to-end solution for e-learning multimedia delivery package for the client-server model. An efficient approach has been proposed to achieve content based embedded scalable motion compensated video compression, for the e-learning videos, to save and/or efficiently utilize the network bandwidth. A bandwidth effective remote lab monitoring system been designed to reduce bandwidth requirements of virtual laboratory system. An efficient approach to achieve the tasks such as, regional language captioning system and keywords based seek, is introduced. The work presented in this dissertation will deal with the issue of intelligent transmission of important segments of the video sequence over scarce resource networks. We incorporate the knowledge of the network conditions to determine how various parts of the video frames are encoded. An estimate of the available network bandwidth is obtained which is then distributed optimally between the different frame constituents based on their relative importance and motion by the bandwidth allocation module. The functioning of Multilanguage content retrieval and management system avails the authoring and displaying of Multilanguage subtitled multimedia content in an effective manner. This system also encompasses a keyword based search and seeks in the authored document with the help of a player. For availing virtual laboratory environment, designed a system that provides remote lab monitoring, doubt resolution, synchronous teacher and student participation. The system acts as an alternative to a laboratory session. Instructor can continuously monitor students and Students can interact with the Instructor at any time they want during the laboratory hours.
