摘要： A device and method of rendering visual information combine image information like video and secondary image information, like graphics. The image information and the secondary image information are processed for generating output information to be rendered in a three-dimensional space. The output information is arranged for display on a 3D stereoscopic display having a true display depth range (44). The processing includes detecting an image depth range of the image information, and detecting a secondary depth range of the secondary visual information. In the display depth range (44), a first sub-range (41) and second sub-range (43) are determined, which first sub-range and second sub-range are non-overlapping. The image depth range is accommodated in the first sub-range and the secondary depth range is accommodated in the second sub-range. Advantageously graphics and video are displayed in true 3D without video objects occluding graphical objects.

摘要： A system (1) for producing a depth map of a video sequence comprises a client (C) and a server (S) connected by a network (N). A secondary video sequence (M*) available at the client (C) is derived from a primary video sequence (M) available at the server (S), the primary video sequence (M) having a primary depth map (D). The server comprises a transmission unit for transmitting the primary depth map (D) to the client. The client comprises an alignment unit for aligning the primary depth map (D) with the secondary video sequence (M*) so as to produce alignment information (AI), and a derivation unit for deriving the secondary depth map (D*) from the primary depth map (D) using the alignment information (AI).

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.
