Abstract: The present invention relates to a control device for providing a recommendation for at least one physical environment for an activity and for providing a recommendation for at least one activity in a physical environment. Such a control device is suitable for users working in flexible office environments and can thus be used for easily locating spaces that suit the users' needs for the current work task. Using historical data mined from embedded sensors in the offices in conjunction with a user's preferences as to how he likes a location to be, a suitability rating can be generated in real time. This enables users to find locations that can suit not only their tangible needs (i.e. luminaires, furniture, equipment, windows etc.) but also their intangible and personal needs (i.e. temperature, light level, busyness, noise levels, humidity, activity etc.).

Abstract: The invention relates to the translation of lighting experience, particularly to the translation of scripts for describing lighting experiences and provided for controlling of lighting devices in a lighting system. An embodiment of the invention provides a method for lighting experience translation by means of a computer, comprising the acts of—receiving an effect based script, which describes one or more light effects of the lighting experience on one or more locations in a view in an environment (S10),—receiving one or more location-effect control models, wherein a location-effect control model describes light effects being available on a location in the view in the environment (S12), and—translating the effect based script into controls for one or more virtual lighting devices by using the location effect control model (S14).

Abstract: The invention relates to the control of a lighting infrastructure such as a complex lighting system. An embodiment of the invention provides a method for controlling a lighting infrastructure by means of a computer comprising the acts of generating a single room view (10) of a room with the lighting infrastructure by combining different views of the room on a display (12; S10), —receiving and processing of input signals (14) with regard to the generated single room view (S12), and —creating output signals (16) for controlling the lighting infrastructure in response to the processed input signals (S14). The single room view allows an intuitive control of a lighting infrastructure similar to a computer paint program.

Abstract: The invention relates to composing a lighting atmosphere from an abstract description for example a lighting atmosphere specified in XML, wherein the lighting atmosphere is generated by several lighting devices, by automatically rendering the desired lighting atmosphere from the abstract description. The abstract description describes the type of light with certain lighting parameters desired at certain semantic locations at certain semantic times. This abstract atmosphere description is automatically transferred to a specific instance of a lighting system (14, 16, 18). The invention has the main advantage that it allows to create light scenes and lighting atmospheres at a high level of abstraction without requiring the definition of a lighting atmosphere or scene by setting the intensity, color, etc. for single lighting units or devices which can be very time consuming and cumbersome, particularly with large and complex lighting systems comprising many lighting devices.

Abstract: Interactive lighting control system (and method) for controlling and creating of light effects such as the tuning of light scenes based on location indication received from an input device. A basic idea of the claimed system is to provide an interactive lighting control by combining a location indication with a light effect driven approach in lighting control in order to improve the creating of light effects such as the tuning of light scenes especially with large and diverse lighting infrastructures.

Abstract: The invention relates to a method of controlling a lighting system with multiple controllable light sources 3a, 3b and a system therefor. According to a first aspect, influence data of the lighting system are obtained, which data represent the effect of one or more of the light sources 3a, 3b on the illumination of one or more sections of an illuminated environment. In an optimization method, sets of control commands are continuously determined, a predicted light distribution for these control commands is determined from the influence data, and a colorimetric difference between the predicted light distribution and a target light distribution is determined. A plurality of adjustment steps are performed to minimize the colorimetric difference. According to a second aspect, a neural network is trained with the influence data and a set of control commands for controlling the lighting system is determined with the use of the neural network.

Abstract: The invention relates in general to an apparatus and a method for modifying a light scene. According to an embodiment of the invention, an apparatus (204) for modifying a light scene composed from an abstract description is provided, wherein the apparatus comprises means (252) for selecting an area of the light scene, means (254) for modifying a light condition of the area, means (256) for recording at least one parameter referring to a modification of the light condition of the area and means (258) for adapting the abstract description based on the at least one parameter.

Abstract: The invention relates to automatically verifying the possibility of rendering a lighting atmosphere from an abstract description, for example from a lighting atmosphere specified in XML (Extensible Markup Language) independent of a specific lighting infrastructure and of a room layout. A basic idea of the invention is to translate the possibilities of a lighting infrastructure into so called light element templates. A light element template contains an indication of the possibilities of the lighting infrastructure at a certain semantic location, for example in a shop or a home in which the lighting infrastructure is provided. For every type of light effect of a lighting infrastructure, a different light element template may be created. This allows to automatically verify the possibility of rendering a lighting atmosphere from an abstract description in a lighting infrastructure at an early stage of the lighting atmosphere design process.

Abstract: A receiving device for securely storing a content item on a storage medium is disclosed. The content item is stored in a secure format, and has an associated license file. The license file is encrypted using public key associated with a group of playback devices, so that each playback device in the group can decrypt the license file and play the content item, but devices outside the group cannot. A playback device can provide a device-specific public key to a Content Distribution Management System (CDMS). The CDMS then returns the secret key for the group encrypted with the public key of the playback device. The playback device then securely obtains the secret key of the group and is subsequently able to decrypt the license file.

Abstract: A receiving device (110) for securely storing a content item (102) on a storage medium (111). The content item (102) is stored in a secure format, and has an associated license file. The license file (141) is encrypted using public key associated with a group of playback devices (120, 121), so that each playback device (121) in the group can decrypt the license file (141) and play the content item (102), but devices outside the group cannot. A playback device (121) can provide a device-specific public key to a Content Distribution Management System (CDMS). The CDMS then returns the secret key for the group encrypted with the public key of the playback device (121). The playback device (121) then securely obtains the secret key of the group and is subsequently able to decrypt the license file (141).
