Despite the development of mobile networks, it is still challenging for current mobile networks to cope with enormous amounts of vehicle video traffic. In this paper, we present a video delivery solution, which is designed to provide steady video content delivery for high-speed vehicles. Our solution improves the steadiness of the video deliveries to vehicle users by a multi-path concurrent delivery mechanism and a path-based content pre-caching mechanism. The concurrent content delivery and content pre-caching can shorten the whole delivery time. However, it sometimes brings heavy stress to the network if the advanced delivery is not controlled. We propose a distributed delivery rate control method to solve the above problem. By the proposed content pre-caching mechanism, each basestation caches appropriate video chunks such that these cached chunks can be used with high probability when the vehicle is within the coverage of the basestation.
