Abstract
Abstract An apparatus for successive refinement of video frames, and methods of operating the same result in reduced latency for downloading the video frames. The apparatus for transmitting video frames comprises a plurality of video frames encoded to provide a plurality of program modules. A first program module provides a first video frame. A second program module provides an enhancement to the first video frame. A cataloging resource which provides scheduling requests for transmission of the plurality of program modules requests the first program module and the second program module for transmission. An output driver which transmits program modules receives the scheduling requests from the cataloging resource for the first program module and the second program module and selects the first program module and the second program module for transmission to produce a higher quality first video frame.
