Abstract
Stream-switching techniques are applied in a content delivery system. A merge frame is generated as a function of bit-rates, distortion, and a piecewise constant operator. Parameters of the piecewise constant operator are selected to optimize the merge frame. Data streams are switched based on bandwidth requirements, switch requests, and throughput of a network. Images are reconstructed based on the merge frames and prediction frames. Reconstructed images are identically reconstructed for any prediction frame based on the merge frame.
