A Hybrid Architecture for Video Transmission

Qian Huang, Xiaoqi Wang, Xiaodan Du, Feng Ye


With the advance of hardware and network technologies, video transmission becomes increasingly popular, especially through mobile networks. Take different networks and displays into account, a hybrid video transmission architecture is presented. Firstly, captured videos are compressed using a H.264/AVC hard coding module, packed with RTP/RTCP protocols, and sent based on UDP sockets. Secondly, a cloud server is built to forward video streams to end users. To improve the security, Ngrok, an open source reverse proxy project, is included. Finally at the client side, video data are unpacked and decompressed, and then post-processed according to the types of end devices. Experimental results show that no obvious time delays are observed, whereas the transmission bandwidths and packet loss rates are acceptable.
