The present system is a“just-in-time”approach that locates an online video file when it is requested by an online or mobile application, transfers it from the Web server, transcodes it, and serves it to the mobile handset in the appropriate format, speed, frame-size, and streaming method. Latency is low, with an acceptable balance between user experience and flexibility. Once a video has been transferred to the system, it is cached so it remains available for instant delivery on subsequent requests.
