With the proliferation of various types of automotive electronic equipment, the existing in-car network can not meet the growing demand. FlexRay, CAN, LVDS and FlexRay are widely used in premium car, but these network are not compatible, we need gateway to connect each other to communicate. So the wiring in car is complicated and quiet heavy. The next generation car network demands larger bandwidth, lower latency and more equipment access. Therefore, high bandwidth, low cost, low latency and easy-deploy network is under study. In last decade? IEEE802.1 Audio Video Bridging(AVB) has been proved to be an option solution. AVB use accurate time synchronization, bandwidth reservation and Credit based Shaping(CBS) algorithm to guarantee high rate and low latency transmission for AVB traffic. R-car T2 is the first car-film SoC support AVB protocol and will be used in future ADAS. In this paper, we analyzed AVB protocol and designed a video capture device using R-car T2 to test the AVB performance.
