    Abstract: A communication network (10) comprising communication nodes (20, 20a, 40, 60, 70, 80, 90) operable to communicate data therebetween. The nodes (20, 20a, 40, 60, 70, 80, 90) include a mobile station (80) being operable to cooperate with first and second corresponding access points (70, 90), the first access point (70) being operable to provide a first communication route to the mobile station (80), and the second access point (90) being operable to sense operation of the first access point (70). The second access point (90) is operable to provide a second communication route to said at least one station (80) in an event of the first access point (70) ceasing to provide said first communication route. The sensing occurs in operation during slot periods (310, 320, 330, 340) individually assigned to the access points (70, 90). Moreover, the slot periods arise within signals (300) communicated within the network (10) for the access points (70, 90) to acknowledge receipt of messages from or to the mobile station (80).

    Abstract: Coded light has been proposed to enable advanced control of light sources and transmit information using light sources. It is based on invisibly embedding of data and identifiers in their light output. Methods, devices and systems configured to efficient assignment of addresses in a coded lighting system, still allowing for unique identification, are proposed. More specifically, the assignment of addresses occurs in two phases, where in the initial phase wide area unique addresses are used, while in the second phase only local area unique addresses are used. Also, methods, devices and systems configured to efficiently distribute a set of addresses over a set of light sources in this second phase, to maximize the performance of the illumination contribution estimation, and positioning, are disclosed.

    Abstract: Controlling a lighting system, which comprises a controller (2, 10), lighting units (6), and a sensing device. Each lighting unit comprises a lighting source (12) and a modulated light source (14). A single light source may be used to function as both the lighting source and the modulated light source. Each modulated light source emits uniquely modulated light. A radiation pattern of each modulated light source coincides substantially with a radiation pattern of a lighting source of the same lighting unit. The sensing device is suitable to sense modulated light in a viewing area. Lighting units from which the sensing device senses modulated light are identified from the modulation of that modulated light. The sensing device measures the intensity of the modulated light from the identified lighting unit. The lighting sources are controlled dependent on control data which comprises measuring values of measured light intensities.

    Abstract: The invention relates to a watermark embedding method and to transcoding and digital recording apparatus including a facility for watermark embedding. A first embodiment incorporates a watermark embedding system with a cascaded decoder/encoder transcoder of the type commonly found in digital recording apparatuses. An input data stream in a first format is received by a decoder (10) of the transcoder. Coding parameters are fed from a first output of the decoder (10) to a first input of an encoder (30) of the transcoder. A second output of the decoder (10) comprises a baseband video signal which is passed to a first input of an adder (24). An output of a watermark generator (22) is fed to a second input of the adder (24). An output of the adder (24) is fed to a second input of the encoder 30. The output of the encoder (30) comprises the information to be recorded in a second format which is compatible with a storage medium.

    Abstract: The present invention relates to a location commissioning method for a lighting system, which comprises several lighting arrangements. Thus, an illuminated position, of for example a room, is selected for the performing the commissioning, which is then associated with that position. This commissioning is called luxissioning TM . The position is assigned a position id, and the light at the position is measured. Light data associated with each one of the lighting arrangements is derived from the measured light, and the light data is associated with the position id. Light transfer data is determined on basis of the light data and current drive data for the lighting arrangements and stored in a light effect setting array for the position id. A light effect setting method is also present, where there is requested a selected light effect at a selected position. For each such request data comprising a position id and a target light effect setting associated with the position is received. The associated initial light effect setting array is derived, for example by retrieving a stored one. Required drive data for the relevant light arrangements, for obtaining the target light effect setting, is determined by means of the light transfer data held in the array, and adjustments are made accordingly, if necessary. Devices and systems for performing the above methods are also addressed by this invention.

    Abstract: Methods and arrangements are disclosed for embedding and detecting a watermark in a cinema movie, such that the watermark can be detected in a copy made by a handheld video camera. The watermark embedder divides each image frame into two areas. A watermark bit ‘+1’ is embedded in a frame by increasing the luminance of the first part and decreasing the luminance of the second part. A watermark bit ‘-1’ is embedded by decreasing the luminance of the first part and increasing the luminance of the second part. It is achieved with the invention that the embedded watermark survives ‘de-flicker’ operations that are often used to remove flicker caused by the different frame rates of cinema projection equipment and consumer camcorders.
