摘要: To allow better quality rendering of video on any display, a method is proposed of encoding, in addition to video data (VID), additional data (DD), wherein the additional data includes at least one change time instant (TMA_1) indicating a change in time of a characteristic luminance (CHRLUM) of the video data, which characteristic luminance summarizes a set of luminances of pixels in an image of the video data, the method: generates on the basis of the video data (VID) descriptive data (DED) regarding the characteristic luminance variation of the video, the descriptive data comprising at least one change time instant (TMA_1), and encodes and outputs the descriptive data (DED) as additional data (DD).

The apparatus comprises a first picture processor (203, 211) which includes image encoding data for an encoded first image in the first pixelised picture. A second picture processor (205, 207, 209, 211) includes dynamic range extension data in the second 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. The dynamic range extension data may be included in a luminance component and comprise data representing a dynamic range extension transform for generating an increased dynamic range image from the encoded first image.

摘要: An apparatus generates an image coding signal comprising for each image a first pixelized picture and a second pixelized picture having a luminance component and a chroma component. The apparatus comprises a first picture processor (203, 211) which includes image encoding data for an encoded first image in the first pixelized picture. A second picture processor (205, 207, 209, 211) includes dynamic range extension data in the second pixelized picture. The dynamic range extension data may be dynamic range extension data included in a chroma component of the second pixelized 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.

摘要: 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.

摘要: An autostereoscopic display device uses an electroluminescent display. A set of pixels is provided beneath lenticular lenses, with a plurality of pixels across the lens width direction. The pixels across the lens width direction are arranged with at least two different heights over the substrate. This enables the pixels to define a non-planar array, and they can follow the area to which light is focused by the lenticular lenses.

摘要: A content distribution system (300) has access control according to a predefined data access format. The system has organizations (32) for providing content data and related meta data on record carriers (34), and a rendering device (39), and applications for manipulating the content data and related meta data. An access policy for the organization is set according to the predefined data access format, and has access parameters for controlling access to resources of the rendering device and to said content data and related meta data. An organization application (35) complying with the access policy of the organization for accessing said data is executed while accessing the resources of the rendering device according to the access policy of the organization. According to the invention a user access policy is maintained that restricts, for the organization application, access to the resources of the rendering device relative to the access policy of the organization. The user access policy is adjusted based on additional trust data for selectively allowing the organization application to access the resources according to the access policy of the organization. Hence the user controls the access that applications have to resources of the rendering device.

摘要: 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.
