Abstract

Lighting system and method examples offer an immersive lighting environment. A multimedia interface of a receiver obtains multimedia content that includes video data, audio data and embedded lighting information. A receiver includes a processor to generate lighting commands for each of a number of luminaires based on the embedded lighting information from the multimedia content. A network interface of the receiver sends respective lighting commands to each of the luminaires, so that operations of controllable light sources of the luminaires are based on the received respective lighting commands (based on the embedded lighting information). This approach, for example, enables coordination of lighting in a venue with the output of the associated video and/or audio multimedia content. The lighting information may be scripted as part of multimedia content creation and/or created or adapted by crowd sourcing or machine learning of customer preferences.

First claim

1 . An immersive lighting system, comprising:
a data network; luminaires, each respective one of the luminaires comprising:
a controllable light source positioned to output light in a space where a multimedia system displays video and outputs audio;
a network interface to enable the respective luminaire to receive communications via the data network; and
a central processing unit, coupled to the light source of the respective luminaire and to the network interface of the respective luminaire, configured to control operation of the light source of the respective luminaire based on respective lighting commands received via the network interface of the respective luminaire; and
a receiver, comprising:
a multimedia interface to obtain multimedia content, the multimedia content comprising video data and audio data intended to also be received by the multimedia system, wherein the multimedia content further comprises embedded lighting information;
a network interface to enable the receiver to communicate with the luminaires over the data network; and
a processor coupled to the network interface and to the multimedia interface, the processor being configured to:
generate the respective lighting commands for each respective one of the luminaires based on the embedded lighting information from the multimedia content; and
cause the network interface of the receiver to send respective lighting commands via the data network to each respective one of the luminaires,

wherein each respective luminaire is configured to receive the respective lighting commands via the respective data network and to control operation of the respective controllable light source of the respective luminaire based on the respective lighting commands received from the receiver.

2 . The immersive lighting system of claim 1 , wherein:
the multimedia system includes a display device configured to receive and display image data based on the video data from the multimedia content, and at least one of the luminaires is arranged along a portion of a periphery of the display device.

3 . The immersive lighting system of claim 2 , wherein another of the luminaires is located on a wall or a ceiling of a room in which the display device displays the image data.

4 . The immersive lighting system of claim 1 , wherein the controllable light source in each respective one of the plurality of luminaires is a non-display type light source configured for controllable artificial general illumination.

5 . The immersive lighting system of claim 4 , wherein the controllable light source in each respective one of the plurality of luminaires is at least one of a point light source or a light bar type light source.

6 . An immersive lighting system, comprising:
a data network; luminaires, each respective one of the luminaires comprising:
a controllable light source positioned to output light in a space where a multimedia system displays video and outputs audio;
a network interface to enable the respective luminaire to receive communications via the data network; and
a central processing unit, coupled to the light source of the respective luminaire and to the network interface of the respective luminaire, configured to control operation of the light source of the respective luminaire based on respective lighting commands received via the network interface of the respective luminaire;
a receiver, comprising:
a multimedia interface to obtain multimedia content, the multimedia content comprising video data and audio data intended to also be received by the multimedia system, wherein the multimedia content further comprises embedded lighting information;
a network interface to enable the receiver to communicate with the luminaires over the data network; and
a processor coupled to the network interface and to the multimedia interface, the processor being configured to:
generate the respective lighting commands for each respective one of the luminaires based on the embedded lighting information from the multimedia content and
cause the network interface of the receiver to send respective lighting commands via the data network to each respective one of the luminaires,

wherein each respective luminaire is configured to receive the respective lighting commands via the respective data network and to control operation of the respective controllable light source of the respective luminaire based on the respective lighting commands received from the receiver; and a media player configured to obtain the multimedia content including the video data, the audio data and the embedded lighting information from a multimedia source, and supply the multimedia content obtained from the multimedia source to the multimedia interface of the receiver as a data stream.

7 . The immersive lighting system of claim 6 , wherein the lighting information is embedded as data in predetermined lighting tracks within the multimedia content obtained from the multimedia source and in lighting tracks in the data stream supplied from the media player to the multimedia interface of the receiver.

8 . The immersive lighting system of claim 7 , wherein the processor is further configured to generate respective lighting commands for each of the luminaires based on the embedded lighting information from one or more of the lighting tracks of the data stream supplied from the media player.

9 . The immersive lighting system of claim 8 , wherein the media player is configured to obtain the multimedia content as a digital program content file downloaded or streamed in real-time via a communication interface of the media player.

10 . The immersive lighting system of claim 6 , wherein the media player is configured to:
obtain the multimedia content from a non-transitory computer readable medium having the encoded lighting information in lighting tracks stored thereon together with tracks of the video data and the audio data; and include the lighting information in lighting tracks in the data stream supplied from the media player to the multimedia interface of the receiver.

11 . The immersive lighting system of claim 10 , wherein the processor is further configured to generate respective lighting commands for each of the luminaires based on the embedded lighting information from one or more of the lighting tracks of the data stream supplied from the media player.

12 . The immersive lighting system of claim 10 , wherein the non-transitory computer readable medium is a compact disk read only memory (CD-ROM), a digital video disk (DVD), a digital video disk read only memory (DVD-ROM), a high definition DVD, or an ultra-high definition DVD.

13 . The immersive lighting system of claim 1 , wherein:
the processor and the network interface of the receiver together operate as a lighting controller relative to the luminaires; the lighting controller supports a plurality of lighting control communication protocols adapted to communicate with different types of luminaires; and the lighting controller implements at least a selected one of the lighting control communication protocols for the communication of the lighting commands to the luminaires of the immersive lighting system.

14 . The immersive lighting system of claim 1 , wherein:
the network interface of the receiver comprises a wireless transceiver; each of the network interfaces of the luminaires comprises a wireless transceiver compatible with over-the-air communications with the wireless transceiver of the receiver; the data network is a wireless network formed by the wireless transceivers of the receiver and the luminaires; and the respective lighting
