    Abstract: Source 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 source 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.

    Abstract: Particular embodiments described herein provide for an electronic device that includes a display and is configured enabling a low power refresh during a semi-active workload. The electronic device includes a display engine, where the display engine generates a video stream with a frame rate, a display, where the display includes an image viewable by a user and the image is refreshed at a first refresh rate, and a timing controller located in the display, where the timing control receives an indicator from the display engine and uses the indicator to determine that the first refresh rate can be lowered to a second refresh rate without the frame rate of the video stream from the display engine being changed. In an example, the indicator is frame with no image data at the start of the frame. In another example, the indicator is an implicit indictor sent by the display engine.
