There is provided a method for managing the downloading and display of a video program using a mobile device in an networking environment that includes a first radio access network and a second radio access network that has a faster transfer rate than the first network. A layer of video program that has been encoded into multiple layers is downloaded via the first or second network. The downloaded video program is displayed at a playback rate that corresponds to a display quality.
