Abstract: In one aspect, a method includes receiving video content comprising a first data portion comprising parameters that control a visual appearance of frames of video content presented by a content-presentation device. The content-presentation device is communicatively coupled to a light unit that is (i) present in a viewing area of the content-presentation device and (ii) configured to provide ambient light in the viewing area. The method also includes extracting, from the received video content, a second data portion, separate from the first data portion, specifying one or more light control parameters that a controller associated with the light unit is configured to interpret as instructions for controlling the light unit. The method also includes transmitting the extracted second data portion to the controller to facilitate the controller controlling the light unit according to the specified one or more light control parameters.

Abstract: Disclosed herein are system, method and/or computer program product embodiments, and/or combinations and sub-combinations thereof, for enhancing a picture quality of visual content rendered for display by a media device. In an embodiment, the media device reconstructs a video frame from a video signal that is received by the media device, provides the video frame as input to a machine learning model that outputs a set of picture quality parameter values based on the video frame, receives the set of picture quality parameter values output by the machine learning model, modifies the video frame based on the set of picture quality parameter values to generate a modified video frame, and provides the modified video frame to a display device for presentation thereby.
