Dynamic ambient lighting
Systems, methods, software, and data structures that provide dynamic ambient lighting synchronized to a video program being watched in a premises are described herein. A video program may be associated with a predefined lighting scheme that specifies or identifies a time-sequenced set of lighting effects (e.g., flashing police lights, sunrise, explosion, etc.) that are to be performed by the dynamic ambient lighting system time-synchronously with the video program. Components of the dynamic ambient lighting system may extract the lighting scheme from video data, parse the lighting scheme into individual lighting effects, and then control a single-color or multicolor light source associated with each of a plurality of light channels (e.g., front right, rear right, front left, rear left, center, and burst channel, among others) based on time-sequenced lighting primitives defined by each lighting effect. Light sources may be wirelessly controlled, e.g., using an IEEE 802.15.4 or ZigBee-compliant wireless system.
