The Design Of The Automatic HD Recording System ActiveX Plugin Based On MFC

The traditional production method of higher quality courses is to shoot in the classroom during the teaching process by professional camera crews with one or more cameras placed in the classroom, and the lesson finished by post-editing through the tape recorded into non-linear editing software at last. The above process is not only a waste of time, but also the recorded content is humdrum. And the recording process usually has a bad influence on the normal teaching, to a certain extent.The Automatic HD Recording System is a web-based multimedia processing system, which can merge teaching speech, blackboard-writing, students’video and audio with electric handouts together automatically. This system has taken many technologies, which is consist of advanced image intelligent photography technology, full automatic director technology, HD multi-track video technology, real-time recording technology and network technology. The client plugin of this system has provided functions such as living, directing, VOD, online cutting, title editing and so on.This paper mainly discusses the research and design of the front ActiveX plugin in the Automatic HD Recording System based on MFC. According to the different functions, the client ActiveX plugin has been researched and designed by part. The data and program flow charts are shown in each module and living, directing and VOD function are all designed and realized. By test, the videos of the living module and directing module are played smoothly. The control of the network center is convenient and fast. While a single video is played, the switch function of video directing is smoothly and steady. In the VOD module, this system has achieved functions including pause, continue, stop, drag and play. The test result shows that the Automatic HD Recording System runs well and steady.
