Because there are currently probably more than necessary different HDR video coding methods appearing, it is expected that practical communicated HDR videos may in several future scenarios consist of a complicated mix of differently encoded HDR video segments, which may be difficult to decode unless one has our presently presented video decoder () arranged to decode a high dynamic range video consisting of temporally successive images, in which the video is composed of successive time segments (S, S) consisting of a number of temporally successive images (I, I) which have pixel colors, which pixel colors in different time segments are defined by having lumas corresponding to pixel luminances according to different electro-optical transfer functions (EOTF), wherein the images in some of the segments are defined according to dynamically changeable electro-optical transfer functions which are transmitted as a separate function for each temporally successive image, and wherein the images in other segments have lumas defined by a fixed electro-optical transfer function, of which the information is co-communicated in data packages (DRAM) which are transmitted less frequently than the image repetition rate, and wherein at least one of said data packages (DRAM) characterizing the electro-optical transfer function of the image pixel lumas after a moment of change (t) between a first and a second segment is transmitted prior to the moment of change (t); and similarly a corresponding encoder which composes the segmented video stream assuring that at least one correct package (DRAM) describing the EOTF according to which the lumas of a later video segment is coded is received by receivers before the change to a different HDR encoding method segment.

Three dimensional [3D] image data and auxiliary graphical data are combined for rendering on a 3D display () by detecting depth values occurring in the 3D image data, and setting auxiliary depth values for the auxiliary graphical data () adaptively in dependence of the detected depth values. The 3D image data and the auxiliary graphical data at the auxiliary depth value are combined based on the depth values of the 3D image data. First an area of attention () in the 3D image data is detected. A depth pattern for the area of attention is determined, and the auxiliary depth values are set in dependence of the depth pattern.

Method and apparatus for combining 3D image and graphical data

To allow pragmatic insertion of secondary images by an apparatus connected to the final display we invented an image processing apparatus () with an output image connection () for connection to a display (), and an input () for receiving an input image (IM) and metadata specifying at least one luminance mapping function (F_Lt), which luminance mapping function specifies the relationship between luminances in the input image and a second image with an at least 6 times higher or lower maximum luminance, and comprising a graphics generation unit () arranged to determine a secondary image (IMG), and an image composition unit () arranged to compose an output image (IMC) on the basis of the pixel colors of the input image and of the secondary image, characterized in that the image processing apparatus comprises a luminance function selection unit (), which is arranged to output to a metadata output () a copy of the at least one luminance mapping function (F_Lt) in case no secondary image colors arc mixed with the input image, and which is arranged to output a predetermined mapping function (F) in case the output image is not identical to the input image because some pixel colors of the secondary image have been used to change the input image colors.

Remote controllers, positioning systems, and methods configured for the efficient assignment of addresses in a coded lighting positioning system are proposed. Particularly, a proposed remote controller comprises a receiver for receiving coded light from a light source in a coded lighting positioning system, where the coded light comprises an initial light source identifier of the light source. The remote controller also comprises a processing unit for assigning a modified light source identifier to the light source based on the received coded light, and a transmitter for transmitting the modified light source identifier to the light source. The modified light source identifier is a locally unique identifier used to provide positional information.

Efficient address assignment in coded lighting positioning systems

A three dimensional [3D] video signal is processed in a video device (). The device has generating means () for generating an output signal for transferring the video data via a high-speed digital interface like HDMI to a 3D display, which selectively generate a 3D display signal for displaying the 3D video data on a 3D display operative in a 3D mode, a 2D display signal for displaying 2D video data on the 3D display operative in a 2D mode, or a pseudo 2D display signal by including 2D video data in the output signal for displaying the 2D video data on the 3D display operative in the 3D mode. Processing means () detect a request to display 2D video data on the 3D display, while the 3D display is operative in the 3D mode, and, in response to the detection, the generating means are set to generate the pseudo 2D display signal for maintaining the 3D mode of the 3D display.

Switching between 3D and 2D video

A three dimensional [3D] video signal () is provided for transferring to a 3D destination device (). Depth metadata is determined indicative of depths occurring in the 3D video data, which depth metadata includes a near value indicative of depths of video data nearest to a user. The 3D video signal, which comprises the 3D video data, now also includes the depth metadata. The 3D destination device () is enabled to retrieve the depth metadata, to provide auxiliary data, and to position the auxiliary data at an auxiliary depth in dependence of the retrieved metadata for displaying the auxiliary data in combination with the 3D video data such that obscuring the auxiliary data by said nearest video data, and/or disturbing effects at the boundary of the auxiliary data, is avoided.

An authentication method authenticates a first party to a second party, where an operation is performed on condition that the authentication succeeds. If the first party is not authenticated, then if the first party qualifies for a sub-authorization, the operation is still performed. Further, a device that includes a first memory area holding a comparison measure, which is associated with time, and which is also used in said authentication procedure, a second memory area holding a limited list of other parties which have been involved in an authentication procedure with the device, and a third memory area, holding compliance certificates concerning parties of said list.

A remote controller is arranged for selecting a light source among a plurality of light sources. The remote controller has an omnidirectional transmitter and is arranged to instruct, by means of the omnidirectional transmitter, the light sources to transmit a directional signal comprising a code, which is unique for each light source. Further, the remote controller has a directional signal receiver, and is arranged to receive the directional signals from the light sources, and signal comparison circuitry connected with the directional signal receiver. The remote controller is arranged to select one of the light sources on basis of the received directional signals. Furthermore, the remote controller comprises a transmission indicator, which is arranged to generate an indication signal, indicative of a successful omnidirectional transmission, and it is arranged to initiate the selection of one of the light sources by means of the indication signal.

Detection using transmission notification

A hybrid transmission/auto-conversion 3D format and scheme for transmission of 3D data towards various types of 3D displays is described. In the decoder () a stereo-to-depth convertor () generates a depth map. In the 3D video signal additional depth information called depth helper data (DH-bitstr) is sparsely transmitted both in time (partial depths in time) and/or spatially (partial depth within the frames). A depth switcher () selects the partial depths based on an explicit or implicit mechanism for indicating when these are to be used or when the depths must be automatically generated locally. Advantageously disturbing depth errors due to said stereo-to-depth convertor are reduced by the depth helper data.

Depth helper data

Three dimensional [3D] image data and auxiliary graphical data are combined for rendering on a 3D display by detecting depth values occurring in the 3D image data and setting auxiliary depth values for the auxiliary graphical data adaptively in dependence of the detected depth values. The 3D image data and the auxiliary graphical data at the auxiliary depth value are combined based on the depth values of the 3D image data. First an area of attention in the 3D image data is detected. A depth pattern for the area of attention is determined, and the auxiliary depth values are set in dependence of the depth pattern.

There is provided a lighting systemcomprising at least one lighting deviceand a control unitarranged for providing power Pto each lighting device according to a control logic which is based on startup characteristics Cof each lighting device. Thereby a lighting system is provided in which the individual characteristics of the lighting devices are taken into account when controlling the lighting devices. Since the control logic is based on startup characteristics for the lighting devices in the system, as an example, a reduction of the total standby power in the lighting system is achievable.

A method of watermarking a video signal includes encoding the video signal using at least one encoding parameter that is time-varied according to a watermarking pattern. The parameter affects information lost while encoding the signal. The parameter may be a quantization factor corresponding to a particular coefficient of an encoding transform. The parameter may be an element of a quantization matrix corresponding to a particular coefficient in a block DCT transform. The method may be implemented in devices with limited processing resources by means of a software update. The method enables the devices to imprint an encoded signal with a robust watermark, which may survive subsequent decompression and recompression. Alternatively, a video signal may be watermarked by modifying a magnitude of a non-dc spatial frequency component in a manner which varies with time according to a watermarking pattern. Corresponding watermark detection methods and watermarking devices also are disclosed.
