Video conferencing system for distance education

Le résumé fourni par la source

Video conferencing plays vital role in communication which can be point-to-point or multipoint real-time communication between two or more student located at different geographical locations. However, it is very difficult to adjust a video capturing device to focus on faculty, especially in distance education classroom where faculty moves off the camera while delivering lecture. Also in distance education, there is requirement of real-time interaction between faculty and student, getting feedback of student's reactions at remote class to a lecture is very important. For faculty, it is important to control remote classroom camera particularly student's video freely and easily by local control and also it is important for the student located at any one remote classroom to see the interaction video between faculty and student of other remote classroom. However, there is some delay between camera control operations at a remote classroom and actual video image displayed on a local screen. These delays are due to network delay between sender and receiver and due to video compression. To operate remote camera interactively, user must consider these delays while controlling these device. This paper proposes a system for identification and tracking of Active participant with the help of Microsoft Kinect sensor, for the tracking of moving faculty on classroom platform. This paper also proposes solutions for the problems related to real-time interaction between faculty and student and real-time camera control. Here we have discussed latest video encoding and protection technique.
