Problems solved by technology

Also, peripherals may be shared by more than one ambience-creating device (e.g., a TV and a game console), and while relative to the TV a peripheral may be configured in a specific position ("left / front"), relative to the game console It may be configured in another position ("right / rear")
This results in a non-intuitive configuration process that lacks simplicity

Embodiment Construction

[0036] figure 1 An embodiment of a central lighting unit 10 that recognizes the spatial configuration of a plurality of remote light sensing devices 11 , 12 , 13 , 14 is shown in . The central lighting unit 10 is the display screen which embeds the identifiers 1, 2, 3, 4 in the AmbiLight of the screen or in the light elements of the backlight. Typically these light elements are LEDs or gas discharge lamps. Two of the remote light sensing devices are speakers 11, 12 and two are lights 13, 14 such as Philips LivingColor lights. Each light sensing device is placed at a desired location in the same room as the central lighting device. The different identifiers 1, 2, 3 and 4 embedded in them are sent in different directions when light is emitted. The identifier is received by the loudspeakers 11, 12 and the lights 13, 14 and after communication with the central lighting device 10, the correct configuration can be achieved.

Abstract

The present invention relates to light-based communication, and more particularly it relates to methods for configuration of at least one remote light-sensing device, to a central light-emitting unit and to a light-sensing device. According to the invention, spatial configuration of remote light-sensing devices (e.g. peripherals such as loudspeakers or light devices), will be achieved by transmission of embedded identifiers or configuration information in light emitted in a plurality of directions from a central light-emitting unit. With a different identifier or different configuration information for each direction of transmission, the directions can be distinguished from each other. The invention enables a user to place remote light-sensing devices in a desired spatial position and the central light-emitting unit will be able to determine location and spatial function, i.e. for example whether the peripheral is an audio device and / or a lighting device. As a result, the peripherals will be correctly configured without any user interaction required.

Description

technical field [0001] The present invention relates to light-based communication, more particularly it relates to a method for configuration of at least one remote light-sensing device, a central lighting unit and a light-sensing device. Background technique [0002] There is a growing interest in creating a space atmosphere based on home entertainment and multimedia content. In order to create such an atmosphere, a spatial distribution of peripheral equipment is required, including for example loudspeakers, lighting and possibly equipment for vibration, air and scent effects). There will usually be a large number of peripheral devices involved in the creation of the ambience, and it would ideally be desirable to have all of these connected wirelessly and automatically, for them to function properly without any active user configuration. [0003] Traditionally, the link between a multimedia device and its peripherals is a wired connection. Establishing such connections is...
