Abstract
A visual light communication (VLC) medium is used to provide communicative coupling between two or more devices. The communicative coupling supports a variety of functions such as, for example, device discovery, content discovery, and seamless transfer of media between the two or more devices.
Claims10
A method comprising:
- displaying, via visible light, media on a first device, the visible light being originated by a light source, the light source being configured to provide the media on the first device using the visible light produced thereby and to be modulated to provide a visual light communication (VLC) medium, the VLC medium being configured to enable the first device to establish communication with a second device using data or information provided by the visible light from the light source being modulated;
- providing a wake up message from the first device to the second device over an infrared communication medium such that the second device is transitioned out of a sleep mode upon receipt thereof;
- and
- concurrently providing from the first device, via the visible light from the light source being modulated, the data or information to be used to establish communications between the first device and the second device.
1 more element
A system comprising:
- a first device configured to render media thereon, the first device comprising a light source, the light source being configured to render the media on the first device using visible light produced thereby and to be modulated to provide a visual light communication (VLC) medium, the VLC medium being configured to enable the first device to establish communication with one or more devices via the visible light from the light source being modulated, the first device further configured to provide a wake-up message over an infrared communication medium to transition one or more devices out of a sleep mode upon receipt thereof;
- and
- a second device communicatively coupled to the first device via the visible light from the light source being modulated, the second device configured to receive the wake-up message provided by the first device over the infrared communication medium and mobility information provided by the first device over the visible light from the light source being modulated and to use the mobility information to transfer at least a portion of the media from the first device to the second device for rendering in the second device.
