摘要：

The Emergency Medical Video Multiplexing Transport System (EMTS) is designed to support prehospital care by delivering high quality patient's live video streams in an ambulance to emergency doctors in a remote hospital on the basis of satellite communications. The feature is that EMTS divides a patient's live video scene into four pieces and transports the four video streams on four separate network channels. By multiplexing the four video streams, EMTS is able to transport high quality videos through low data transmission rate networks such as satellite communications and cellular phone networks. In order to transport live video streams constantly, EMTS adopts Real-Time Transport Protocol/Real-Time Control Protocol as a network protocol, and video stream data are compressed by Moving Picture Experts Group 4 format. As EMTS combines four video streams with checking video frame numbers, it uses a refresh packet that initializes server's frame numbers to synchronize the four video streams.
