Abstract
Over low-bit-rate network such as the Internet, a video service has problems of video representation delay and degradation of QoS(Quality of Service) because it cannot transmit video data within restricted time. Data compression and transmission techniques have been researched for solving this problems. In this paper, we represent a new real-time VoD(Video on Demand) service system on the Internet. This VoD which is based on the client/server architecture has been developed using ITU-T H.263 video codec which has high compression ratio and good quality of video data and 8.3kbps Truespeech audio codec. Our system can provide a real-time video service according to user demand on the Web browser, and support a tool to generate video streams stored at the video server. In this system, for solving the problems of the real-time VoD service over the Internet, we propose new techniques of buffer control to guaranteed audio/video QoS, synchronization between audio and video, video summary service by use of scene change detection, and etc.
