Abstract
A method and system (11) for transmitting data (21) at receiver-selectable image and motion quality. The data (21) is decomposed into frames, and the frames may be decomposed into bands, with each of the bands adding data to the preceding band. The frames and/or bands are transmitted individually or in groups at different rates on different channels. Each receiver (15) can subscribe to the channels that provide a desired level of image and motion quality for the bandwidth available to each receiver (15).
