Selecting a set of lighting devices based on an identifier of an audio and/or video signal source
A system ( 11 ) for controlling a set of one or more lighting devices ( 31 - 32 ) based on an analysis of audio and/or video content and/or based on a light script associated with the audio and/or video content is configured to receive an audio and/or video signal from a source ( 43 - 45 ), determine an identifier of the source, and select the set of one or more lighting devices from a plurality of lighting devices ( 31 - 34 ) by selecting a set of one or more lighting devices associated with the identifier of the source. The audio and/or video signal comprises the audio and/or video content. The system is further configured to determine light effects based on the analysis of the audio and/or video content and/or based on the light script associated with the audio and/or video content and control the selected set of one or more lighting devices to render the light effects.
1. A system for selecting a set of one or more lighting devices from a plurality of lighting devices and for controlling said selected set of lighting devices, based on analysis of audio and/or video content, said system comprising:
at least one input interface arranged for receiving an audio and/or video signal from a plurality of audio and/or video sources;
at least one output interface arranged for controlling said plurality of lighting devices; and
at least one processor configured to:
receive an audio and/or video signal from an audio and/or video source of the plurality of audio and/or video sources via said at least one input interface, said audio and/or video signal comprising said audio and/or video content,
determine an identifier of said audio and/or video source, said identifier uniquely identifying said audio and/or video source from which the audio and/or video signal is received amongst the plurality of audio and/or video sources,
select said set of one or more lighting devices from the plurality of lighting devices by selecting one or more lighting devices associated with said determined identifier of said audio and/or video source,
analyze said audio and/or video content,
determine light effects based on said analysis of said audio and/or video content, and
control, via said at least one output interface, said selected set of one or more lighting devices to render said determined light effects.
2. A system as claimed in claim 1 , wherein said at least one processor is configured to determine said identifier of said audio and/or video source by determining an identifier of the at least one input interface of said system via which said audio and/or video signal is received from said audio and/or video source.
3. A system as claimed in claim 1 , wherein said at least one processor is configured to determine said identifier of said audio and/or video source by determining an identifier of an input port of a switch coupled to said system via said at least one input interface, said audio and/or video signal being received by the system via said input port of said switch.
4. A system as claimed in claim 3 , wherein said audio and/or video signal comprises said identifier of said input port of said switch when received by said system.
5. A system as claimed in claim 1 , wherein said at least one processor is configured to determine a type of said audio and/or video content and determine said identifier of said audio and/or video sources based on said type of said audio and/or video content.
6. A system as claimed in claim 1 , wherein said at least one processor is configured to:
extract audio and/or image features from said audio and/or video content,
compare said extracted audio and/or image features with a plurality of sets of audio and/or image features, each of said plurality of sets of audio and/or image features being associated with a determined identifier of one of said plurality of audio and/or video sources, and
determine said identifier of said audio and/or video source ( 43 - 45 ) based on said comparison.
7. A system as claimed in claim 1 , wherein said at least one processor is configured to determine said identifier of said audio and/or video source based on metadata included in said audio and/or video signal.
8. A system as claimed in claim 1 , wherein said audio and/or video signal comprises a video signal and wherein said at least one processor is configured to determine a video format of said video signal and determine said identifier of said audio and/or video source based on said determined video format.
9. A system as claimed in claim 1 , wherein said at least one processor is configured to receive user input via said at least one input interface, said user input being indicative of said identifier of said audio and/or video source and indicative of said set of one or more lighting devices, and associate said set of said one or more lighting devices with said identifier.
10. A system as claimed in claim 1 , wherein said at least one processor is configured to detect a new lighting device, ask a user to indicate one or more audio and/or video sources of the plurality of audio and/or video sources with which said new lighting device should be associated, determine an identifier of each of said indicated one or more audio and/or video sources, and associate said new lighting device with said identifier of said indicated one or more audio and/or video sources.
11. A system as claimed in claim 1 , wherein said at least one processor is configured to determine a user identifier of a user using said system and select said set of one or more lighting devices by selecting a set of one or more lighting devices associated with said user identifier and associated with said identifier of said audio and/or video source.
12. A system as claimed in claim 1 , wherein said at least one processor is configured to transmit said identifier of said audio and/or video source to a further system, receive information associated with said identifier from said further system in response to said transmission, and select said set of one or more lighting devices based on said information.
13. A method of selecting a set of one or more lighting devices from a plurality of lighting devices and for controlling said selected set of lighting devices, based on an analysis of audio and/or video content and/or based on a light script associated with said audio and/or video content, said method comprising:
receiving an audio and/or video signal from an audio and/or video source of a plurality of audio and/or video sources, said audio and/or video signal comprising said audio and/or video content;
determining an identifier of said audio and/or video source, said identifier uniquely identifying said audio and/or video source from which the audio and/or video signal is received amongst the plurality of audio and/or video sources;
selecting said set of one or more lighting devices from the plurality of lighting devices by selecting one or more lighting devices associated with said determined identifier of said audio and/or video source;
analyzing said audio and/or video content;
determining light effects based on said analysis of said audio and/or video content and/or based on said light script associated with said audio and/or video content; and
controlling said selected set of one or more lighting devices to render said light effects.
14. A computer program product for a computing device, the computer program product comprising computer program code to perform the method of claim 13 when the computer program product is run on a processor of the computing device.
