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: In one aspect, an example method includes (i) estimating, using a skeletal detection model, a pose of an original actor for each of multiple frames of a video; (ii) obtaining, for each of a plurality of the estimated poses, a respective image of a replacement actor; (iii) obtaining replacement speech in the replacement actor's voice that corresponds to speech of the original actor in the video; (iv) generating, using the estimated poses, the images of the replacement actor, and the replacement speech, synthetic frames corresponding to the multiple frames of the video that depict the replacement actor in place of the original actor, with the synthetic frames including facial expressions for the replacement actor that temporally align with the replacement speech; and (iv) combining the synthetic frames and the replacement speech so as to obtain a synthetic video that replaces the original actor with the replacement actor.

Abstract: A method and system for controlling media-content presentation based on user presence and/or user profile. An example method includes a computing system determining a quantity of users present at a media-presentation device, the quantity being at least one. Further, the example method includes, based on the determining, the computing system using the determined quantity of users present at the media-presentation device as a basis to control what media content a media player outputs for presentation by the media-presentation device. For instance, based on the determined quantity of users the computing system could tailor a graphical user interface (GUI) that the media player outputs for presentation by the media-presentation device, such as by tailoring a set of channel options that a channel-selection GUI provides, among other possibilities.

Abstract: A method and system for dynamically controlling operation of a first device, the first device being configurable to respond to receipt of primitive user input (e.g., push of a button on the first device) by carrying out a control action with respect to one or more second devices. An example method includes detecting a context state such as time of day and/or location of the first device. Further, the example method includes, using the detected context state as a basis to control what control action the first device will take in response to the first device receiving the primitive user input, such as which second device the first device will control in response to receiving the primitive user input and/or controlling what operational state of a second device the first device will control in response to receiving the primitive user input.
