Abstract
An end-to-end lecture broadcast system (LBS) is described. The LBS system typically comprises three modules: a schedule module, a capture module and a transmission module. The schedule module is comprised of a scheduler that is implemented as a software add-on on the lecture host's computing device, a schedule server, and a schedule agent component in the uploading peer to provide for channel based management. The capture module is comprised of a video camera for capturing video content, one or more microphones for capturing audio content, and a VGA signal capture for capturing presentation materials. The transmission module is comprised of an uploading peer and a web server. The uploading peer is responsible for transmitting video/audio content to the Internet/intranet using peer-to-peer (P2P) streaming technology. The web server is responsible for the delivery of captured presentation materials and for ensuring the synchronous play back of video/audio content and presentation materials.
