This paper proposes a new video delivery system with a lightweight, smooth, and quick-response accessibility to video scenes without interference by unstable mobile network conditions and also without consuming mobile device storage. This can avoid a video scene access delay brought on by mobile-network-specific delay and instability. We proposed an innovative streaming technology that consists of a view-context-aware asynchronous prefetching and streaming scheme and a seamless media assembly and media synchronization scheme. As an additional powerful extension for this system, we present a hierarchical prefetching asynchronous streaming technology that considers a videoscene structure. This can provide access to a general view through the whole content as well as to a detailed view around playback position by consideration of the video-scene structure and the user's viewing position. The implementation details on mobile phones and preliminary evaluation results are described, and its feasibility is also shown.
