Abstract

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.

Claims

1. An apparatus, comprising:

a processor; and

memory storing a lighting effects database, wherein each of a plurality of lighting effects stored in the lighting effects database corresponds to a set of sequenced ambient lighting instructions for outputting the lighting effect over a plurality of light sources, and storing computer readable instructions that, when executed by the processor, configure the apparatus to control ambient lighting by;

receiving video data;

querying a lighting scheme database based on the video data to identify a lighting scheme corresponding to the video data, wherein each lighting scheme identifies a timed sequence of lighting effects;

receiving the corresponding lighting scheme;

outputting, based on the video data, video content for display on a display screen operatively connected to the apparatus;

querying the lighting effects database for a set of ambient lighting instructions corresponding to the lighting effects identified in the lighting scheme; and

outputting the corresponding set of ambient lighting instructions time-synchronized with the video content, said ambient lighting instructions performing the lighting effects over a plurality of light channels, wherein each light channel is associated with a location of a different light source of the plurality of light sources in relation to a location of the display screen.

2. The apparatus of claim 1, wherein each ambient lighting instruction defines a light intensity value for each color of a multi-color light source associated with one or more of the light channels.

3. The apparatus of claim 2, wherein each ambient lighting instruction defines a light intensity value for each of a red, blue and green light emitting diode (LED) strand in the multi-color light source.

4. The apparatus of claim 3, wherein each ambient lighting instruction further defines a light intensity value for a white LED strand in the multi-color light source.

5. The apparatus of claim 1, wherein each ambient lighting instruction includes identifying information for one or more of the time sequenced lighting effects.

6. The apparatus of claim 5, wherein a first lighting effect corresponds to a set of sequenced ambient lighting instructions, that, when executed by the plurality of light sources, effect a visual light pattern simulating flashing red and blue lights on a police car.

7. The apparatus of claim 5, wherein a first lighting effect corresponds to a set of sequenced ambient lighting instructions, that, when executed by the plurality of light sources, effect a visual light pattern simulating a searchlight passing over a location of the display screen.

8. The apparatus of claim 1, wherein the plurality of light channels comprise six light channels.

9. The apparatus of claim 8, wherein one of the six light channels comprises a burst channel.

10. The apparatus of claim 1, wherein the video data comprises a program ID, and wherein querying the lighting scheme database comprises querying the lighting scheme database for one or more lighting schemes corresponding to the program ID.

11. The apparatus of claim 10, wherein the instructions further configure the apparatus to, if querying of the lighting scheme database returns a plurality of lighting schemes corresponding to the program ID, select a particular lighting scheme based on an attribute of the particular lighting scheme as compared to a similar attribute of other lighting schemes of the plurality of lighting schemes corresponding to the program ID.

12. A method comprising:

querying a lighting scheme database based on received video data to identify a first lighting scheme corresponding to the video data, wherein the first lighting scheme identifies a sequence of lighting effects time synchronized to the video data;

querying a database of lighting effects for each lighting effect identified in the first lighting scheme, wherein each lighting effect corresponds to a predefined sequence of ambient lighting instructions; and

outputting, from a computing device, the corresponding ambient lighting instructions time-synchronized with the video data and configured to cause performance of the timed sequence of lighting effects over a plurality of light channels associated with a different light source in a predefined location.

13. The method of claim 12, wherein one or more of the light channels comprises a multi-color light source, wherein each ambient lighting instruction corresponding to a same channel as the multi-color light source defines a light intensity value for each color of the multi-color light source.

14. The method of claim 13, wherein each ambient lighting instruction corresponding to the same channel as the multi-color light source defines a light intensity value for each of a red, blue and green light emitting diode (LED) strand in the multi-color light source.

15. The method of claim 12, wherein each ambient lighting instruction includes identifying information for one or more of the time sequenced lighting effects.

16. The method of claim 12, wherein the plurality of light channels comprise a front right channel, a front left channel, a rear right channel, a rear left channel, a center channel and a light burst channel.

17. The method of claim 12, wherein the video data comprises a program ID, and wherein querying the lighting scheme database comprises querying the lighting scheme database for one or more lighting schemes corresponding to the program ID.

18. The method of claim 17, further comprising, if querying of the lighting scheme database returns a plurality of lighting schemes corresponding to the program ID, selecting a particular lighting scheme based on an attribute of the particular lighting scheme as compared to a similar attribute of other lighting schemes of the plurality of lighting schemes corresponding to the program ID.
