| Abstract | With the development of NGN which has SIP as the core protocol, there are more and more video communication services. It becomes focused on how to implement the interception and control in Video communication system based on SIP in real time. This article puts emphases on the character of SIP and the video communication system themselves and puts forward a design of the model. It uses the feature of media information's interaction in signaling of SIP protocol during the media session establishment. At first, the model judges the communicating parties whether they are target users by analyzing the protocol. Then, it modifies the target users' signaling information. So the model can access the communication parties' media stream. And at the same time, the model uses the multi-modal media recognition technology. It uses the shunt to divide accessed media stream into audio and video stream. And it extracts audio, video and text information by analyzing them. Finally, the model uses these three modes to analysis the contained media content. Simulation results show that the model can not only implement the interception and control of the protocol but also recognize the content of media session effectively in real time. |

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.
