Abstract

Sink devices are provided that increase quality of displayed images by dynamically integrating higher fidelity update frames into a base stream encoded using an encoding technique (e.g., chroma-subsampling and/or another lossless encoding technique). Use of base image frames enables backward compatibility with existing technology and serves as a baseline for bandwidth scaling. The fidelity update frames may include raw image data, lossy, or losslessly compressed image data, and/or additional subsampled image data. The image data included in the fidelity update frames may apply to the entire base image frame or a portion thereof. The fidelity update frames may include incremental data or complete, high fidelity image data for a portion of an entire image. The sink devices may store and implement fidelity management policies that control operation of the devices to balance resource consumption against fidelity to meet the needs of specific operational environments.
