Abstract: Quality of Service (QoS) control is of primary importance in successful transmission of video signals over bandwidth limited wireless networks in vehicle surveillance systems. A wireless streaming media transfer platform based on the mixed QoS system is introduced in this paper. The theoretical knowledge related to the QoS and mixed QoS control of the feasibility and characteristics is analysed, and a comprehensive QoS in vehicle surveillance is introduced. This system combines network control and end-to-end QoS control. At both ends, from the delay, jitter, etc. are adjusted by the addition of the timestamp and other information on the dynamic adjustment of the speed of data transmission. Through improving the control of two ends QoS and media streaming forward server, the image/video streaming from vehicle is transferred into the internet by 3G/GPRS and then linked to common internet and mobile phone users through carrier networks (wired and wireless), which realise the real-time supervision.

Keywords: QoS; quality of service; mobile media streaming; vehicle surveillance; congestion control; video signals; wireless networks; internet; mobile phones; cell phones; real-time supervision.
