| Abstract | Interworking between wireless LANs and 3G networks is expected to the best models for vehicle communications. This paper presents an embedded video camera for vehicle over WLAN and CDMA1X. The main objective is to evaluate the conditions and restrictions under which seamless continuity of video sessions across the two networks is feasible. First, it constructs high speed automobile communication environment by wireless access router which can automatically switched between CDMA1X and the WLAN. In order to fit the bandwidths sharply variety of wireless channel, adaptive video compression algorithms based MPEG4 is utilized to encode the high quality video. Moreover, unique transmission mechanism using media server and media gateway is presented, which can support large scale concurrent users up to 1000. This transmission mechanism uses the buffer on media server to smooth the video transport in wireless channel. The live surveillance video of mobile can be viewed over Internet and does not need fix IP address. Furthermore, control center can be set up anywhere with Internet access without being restricted by monitored site locations. Therefore the networked vehicle can achieve seamless roaming and secured network connectivity anytime and anywhere. |

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.
