1. A method comprising:
receiving video content comprising a first data portion comprising video parameters that control a visual appearance of frames of video content presented by a content-presentation device, wherein a light unit is (i) present in a viewing area of the content-presentation device and (ii) configured to provide ambient light in the viewing area, and wherein the content-presentation device is communicatively coupled to a speaker present in the viewing area, wherein the speaker comprises a speaker controller, and wherein the light unit and the speaker are physically separate devices;
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 light unit controller is configured to interpret as instructions for controlling the light unit; and
transmitting the extracted second data portion to the speaker controller to facilitate the light unit controller controlling the light unit according to the one or more light control parameters specified by the extracted second data portion, wherein the speaker controller is configured to, upon receipt of the extracted second data portion, transmit the extracted second data portion to the light unit controller, wherein transmitting the extracted second data portion to the speaker controller comprises transmitting the extracted second data portion to the speaker controller over an unused audio channel between the content-presentation device and the speaker.
