A novel real-time video transmission approach for remote laboratory development

Remote laboratories are an inevitable necessity for Internet enabled education in Science, Technology, Engineering, and Math (STEM) fields due to their effectiveness, flexibility, cost savings, and the fact that they provide many benefits to students, instructors and researchers. Accordingly, real-time experiment live video streaming is an essential part of remote experimentation operation. Nevertheless, in the development of real-time experiment video transmission, it is a key and difficult issue that the video is transferred across the network firewall in most of the current remote laboratory solutions. To address the network firewall issue, we developed a complete novel solution via HTTP Live Streaming (HLS) protocol and FFMPEG that is a powerful cross-platform command line video transcode/encoding software package on the server side. In this paper, a novel, real-time video streaming transmission approach based on HLS for the remote laboratory development is presented. (…)
