Abstract: 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 (20) a stereo-to-depth convertor (24) 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 (25) 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.

Abstract: A 3D video system for transmission of 3D data towards various types of 3D displays is described. A 3D source device (40) provides a three dimensional [3D] video signal (41) to a 3D destination device (50). The 3D destination device receives the 3D video signal, and has a destination depth processor (52) for providing a destination depth map for enabling warping of views for the 3D display. The 3D source device generates depth signaling data, which represents depth processing conditions for adapting, to the 3D display, the destination depth map or the warping of views. The 3D video signal contains the depth signaling data. The destination depth processor adapts, to the 3D display, the destination depth map or the warping of views in dependence on the depth signaling data. The depth signaling data enables the rendering process to get better results out of the depth data for the actual 3D display.

Abstract: When the user views the information available on a program (in a Personal Video Recorder), the keywords that determine whether a program will be recorded are accentuated. This can be done by using the size of the text or by using colors or any other kind of varying accentuation i.e. encircled or blinking text. This makes it easy for the user to identify the keywords used in their personalized profile. Additionally the user can navigate between keywords and change the accentuation of the keywords, to indicate a rating (in multiple levels) of the keyword.

Abstract: An image processor processes an assembly of data that defines an elementary image and a graphics object. The assembly of data includes composition data that defines a given appearance of the graphics object in an output image, where the graphics object overlays a portion of the elementary image. The image processor includes an occlusion analyzer for establishing an occlusion indication based on the composition data. The occlusion indication specifies an area in the elementary image that the graphics object will occlude in the output image, but which may be de-occluded in a stereoscopic rendering of the output image. An occlusion data generator composes an occlusion image based on the occlusion indication and the elementary image. The occlusion image represents a portion of the elementary image that corresponds with the area specified by the occlusion indication.

Abstract: An autostereoscopic display device comprises a display arrangement such as an emissive display arrangement or an reflective display arrangement, with an array of spaced pixels. A light guiding arrangement has an array of light guide columns, with one column over each display pixel or over a group (such as a column) of pixels. The light guide columns comprise aside wall which tapers outwardly to define a funnel shape with the pixel at the smaller base of the funnel. The funnel provides collimation to reduce cross talk in the display, which is particularly problematic for 3D autostereoscopic displays.

Abstract: A lenticular lens based autostereoscopic display arrangement uses a display arrangement such as an emissive display arrangement or a reflective display arrangement. The interface between adjacent lenticular lenses (49) is interrupted by a light shielding arrangement (50), which extends at least from the lens surface at the interface into the lens structure, thereby providing a shield extending beneath the lens surface. This reduces lateral progression of light in the lenticular lens arrangement and thereby reduces cross talk caused by waveguiding in the lens material.

Abstract: An apparatus generates an image signal in which pixels are encoded in N-bit words which encode at least a luma per pixel. A receiver (201) obtains high dynamic range pixel values in accordance with a first color representation in M-bitwords. A first generator (203) includes the high dynamic range pixel values in the image signal in the N-bit words according to a second color representation. A second generator (205) includes in the image signal an indicator that high dynamic range pixel values are encoded. In some examples, the high dynamic range pixel values may be provided in a segment that can alternatively contain high or low dynamic range pixel values, and the indicator may indicate which type of data is included. The approach may e.g. facilitate introduction of high dynamic range capability into e.g. HDMI systems.

The apparatus comprises a first picture processor (203, 211) which includes image encoding data for an encoded first image in the first pixelised picture.

The dynamic range extension data may be dynamic range extension data included in a chroma component of the second pixelised picture for generating an increased dynamic range image on the basis of the encoded first image. The compensation data may e.g. be compensation data for correcting another LDR-to-HDR transform, e.g. a prefixed global gamma transformation.

Abstract: A system for transferring 3D video information has a transmitter (100) to broadcast a signal (104) to a receiver (110). The 3D video information includes auxiliary data for display in an overlay area on the 3D video data, like subtitles. The 3D video data has a left view and a right view arranged in a 2D frame in a main arrangement, e.g. side-by-side. An auxiliary left and right view of the auxiliary data are arranged in an auxiliary data stream according to a 2D transmission format in an auxiliary arrangement that corresponds to the main arrangement, e.g. also side-by-side. In addition, a 2D version of the auxiliary data and auxiliary disparity data indicative of the disparity to be applied to the 2D version of auxiliary data when overlayed on the left view and the right view is included in the transport stream. Advantageously the receiver may use a suitable version of the auxiliary data based on the receiver processing architecture.
