Abstract: A data processing system (70) for graphics processing, including a scene manager (80). The scene manager (80) includes a scene loader (86) for receiving a description of 3 dimensional objects in a scene from a 3-dimensional modelling tool (46). The description includes first 2-dimensional frame data. The scene manager (80) has a texture image modification unit (84) for receiving second 2-dimensional frame data from a 2-dimensional rendering engine (40), and for replacing the first frame data by the second frame data. The scene manager (80) has an animation scheduler for scheduling and monitoring an animation of the scene. The system includes a display manager (96) operative to invoke the scene manager (80) to render output frames in a display buffer (100), and a scene Tenderer (88) configured for applying the 2-dimensional frame data to the 3-dimensional objects to produce textured 3-dimensional objects in the display buffer (100) and outputting the textured objects in the animation.

Abstract: In one embodiment, a method implemented on a computing device includes: receiving one or more video mosaic source services, each of the one or more video mosaic source services comprising a plurality of cells, each cell being associated with a content source; receiving signaling data, the signaling data comprising at least one attribute defining a current content available on a content source; receiving a request specifying an attribute to use for producing a mosaic presentation screen; and upon receiving the request, compositing cells extracted from the received one or more video mosaic source services into a mosaic presentation screen, the composited cells being associated with content sources whose current content attribute corresponds to the specified attribute.

Abstract: A method and apparatus is described to display a customized video sequence during a channel change interval. The method includes displaying a first channel; receiving a channel change request from a user requesting a second channel for display; displaying a video sequence during the channel change interval; and displaying a second channel; characterized in that the displaying of the video sequence during the channel change interval further comprises displaying a black screen with no audio and no video for a short duration; playing out a first portion of a customized video sequence relevant to the second channel entirely; and playing out a second portion of the customized video sequence relevant to the second channel until the second channel is ready to be displayed.

Abstract: A method of operating a client device within a viewing environment is described. The method includes: receiving content at a client device, presenting the content to a viewer by rendering the content as rendered content on a display surface in operable communication with the client device; receiving engagement data at the client device, the engagement data indicating a level of engagement with the content of at least one user who is viewing the rendered content; and adapting presentation of the content in dependence on the engagement data by changing how the content is rendered on the display surface. Related systems, apparatus, and methods are also described.

Abstract: A method for managing windows in a window-based display system, the method comprising providing a plurality of windows, each window being associated with an application, at least one of the plurality of windows being able to accept focus, assigning, to each one of the plurality of windows being able to accept focus, a focus priority, assigning focus to exactly one window at any time by choosing, from among the at least one of the plurality of windows able to accept focus, a window having a highest focus priority of the windows able to accept focus, and designating the chosen window as an active window. Related apparatus and methods are also described.
