Abstract
Due to the development of wireless communication technology, more and more streamers are using cameras mounted on mobile devices for live streaming in a wireless LAN environment. Conventional live streaming systems, which employ multiple images captured by multiple cameras, require relay equipment for transmitting images to a computer for streaming and a network environment with sufficient bandwidth for live streaming. Therefore, the restrictions on using live streaming systems by streamers are severe. In this paper, we propose a multi-view live streaming system using multiple mobile devices in a wireless LAN environment. Our proposed system reduces the processing load on live streaming by using video streaming functions implemented on several mobile devices based on WebRTC. By sending and receiving data between mobile devices, the proposed system also reduces the bandwidth needed for delivering data. Furthermore, with a video switching function during live streaming, the system can dynamically change viewpoints. Performance evaluation results using the proposed system confirmed that the delay time between transmitting and delivering devices can be reduced compared to conventional systems that apply Motion-JPEG and RTMP.
