Abstract

Methods, apparatus, systems and articles of manufacture are disclosed to adjust device control information. The example apparatus comprises a light drive waveform generator to obtain metadata corresponding to media and generate device control information based on the metadata, the device control information to inform a lighting device to enable consecutive light pulses; an effect engine to apply an attack parameter and a decay parameter to consecutive light pulses corresponding to the device control information, the attack parameter and the decay parameter based on the metadata to affect a shape of the consecutive light pulses; and a color timeline generator to generate color information based on the metadata, the color information to inform the lighting device to change a color state.

First claim

What is claimed is:

1. An apparatus to adjust device control information, the apparatus comprising:
a light drive waveform generator to obtain metadata corresponding to media and generate device control information based on the metadata, the device control information to inform a lighting device to enable consecutive light pulses;
an effect engine to:
initialize an envelope with predetermined specifications based on the metadata, the predetermined specifications including an attack parameter and a decay parameter; and
apply the attack parameter and the decay parameter to consecutive light pulses corresponding to the device control information, the attack parameter and the decay parameter to affect a shape of the consecutive light pulses; and

a color timeline generator to generate color information based on the metadata, the color information to inform the lighting device to change a color state.

2. The apparatus of claim 1 , further including a filter network to apply a smoothing filter to the color information when the color information is indicative of a change from a first color state to a second color state.

3. The apparatus of claim 2 , wherein the smoothing filter is to reduce an abruptness of the change from the first color state to the second color state.

4. The apparatus of claim 1 , wherein the metadata includes mood information, tempo information, genre information, and energy level information corresponding to media.

5. The apparatus of claim 1 , wherein the metadata corresponds to mood information.

6. The apparatus of claim 1 , wherein the metadata corresponds to genre information.

7. The apparatus of claim 1 , wherein the effect engine is to initialize an envelope to modulate the consecutive light pulses.

8. The apparatus of claim 1 , wherein the effect engine is to initialize a filter to adjust an amplitude of the consecutive light pulses based on an energy of the media.

9. A non-transitory computer readable storage medium comprising computer readable instructions that, when executed, cause at least one processor to at least:
obtain metadata corresponding to media and generate device control information based on the metadata, the device control information to inform a lighting device to enable consecutive light pulses;
initialize an envelope with predetermined specifications based on the metadata, the predetermined specifications including an attack parameter and a decay parameter;
apply the attack parameter and the decay parameter to consecutive light pulses corresponding to the device control information, the attack parameter and the decay parameter to affect a shape of the consecutive light pulses; and
generate color information based on the metadata, the color information to inform the lighting device to change a color state.

10. The non-transitory computer readable storage medium of claim 9 , wherein the computer readable instructions, when executed, cause the at least one processor to apply a smoothing filter to the color information when the color information is indicative of a change from a first color state to a second color state.

11. The non-transitory computer readable storage medium of claim 10 , wherein the computer readable instructions, when executed, cause the at least one processor to reduce an abruptness of the change from the first color state to the second color state.

12. The non-transitory computer readable storage medium of claim 9 , wherein the computer readable instructions, when executed, cause the at least one processor to initialize the envelope with predetermined specifications corresponding to mood information.

13. The non-transitory computer readable storage medium of claim 9 , wherein the computer readable instructions, when executed, cause the at least one processor to initialize the envelope with predetermined specifications corresponding to genre information.

14. The non-transitory computer readable storage medium of claim 13 , wherein the computer readable instructions, when executed, cause the at least one processor to initialize an envelope to modulate the consecutive light pulses.

15. The non-transitory computer readable storage medium of claim 9 , wherein the computer readable instructions, when executed, cause the at least one processor to initialize a filter to adjust an amplitude of the consecutive light pulses based on an energy of the media.

16. A method comprising:
obtaining metadata corresponding to media and generating device control information based on the metadata, the device control information to inform a lighting device to enable consecutive light pulses;
initializing an envelope with predetermined specifications based on the metadata, the predetermined specifications including an attack parameter and a decay parameter;
applying the attack parameter and the decay parameter to consecutive light pulses corresponding to the device control information, the attack parameter and the decay parameter to affect a shape of the consecutive light pulses; and
generating color information based on the metadata, the color information to inform the lighting device to change a color state.

17. The method of claim 16 , further including applying a smoothing filter to the color information when the color information is indicative of a change from a first color state to a second color state.

18. The method of claim 17 , wherein the smoothing filter is to reduce an abruptness of the change from the first color state to the second color state.

19. The method of claim 16 , further including initializing the envelope with predetermined specifications corresponding to mood information.

20. The method of claim 16 , further including initializing a filter to adjust an amplitude of the consecutive light pulses based on an energy of the media.
