Abstract: A method of compositing a plurality of graphic objects with a compositing buffer, is disclosed. The plurality of graphic objects forming a group is attenuated by group opacity and is composited from a top object to a bottom object. Based on a first mask and the group opacity, a second mask is generated. The first mask stores a remaining possible contribution for further graphic objects below and including the plurality of graphic objects. The plurality of graphic objects in a top down order is processed. In particular, for each graphic object of the plurality of graphic objects: (a) a contribution value for the graphic object using the second mask is determined, the contribution value representing a contribution of the graphic object to the compositing buffer; (b) a colour value of the graphic object is composited with the compositing buffer using the contribution value; and (c) the second mask is updated using the contribution value. The first mask is then updated using the second mask and the group opacity.

Abstract: A change in field order between an input video frame and an output video frame or an input video frame being displaced by an odd number of scan-lines with respect to an output video frame, may introduce out of order fields in the output video frame. A method (700), apparatus and computer program product for generating an interlaced video stream from one or more interlaced input video streams and graphical objects is disclosed. The method (700) enables input video streams to be transformed (e.g., scaled and translated) to generate an interlaced video stream. The method (700) ensure that the fields of an output video frame are in correct order by shifting a corresponding input video frame down by one scan-line.

Abstract: A video node for use in rendering one or more video frames of a video stream. The video node is represented by a compositing tree (2100). The compositing tree (2100) comprises at least one image primitive node (2140) representing one or more video frames (2300) of the video stream. At least one of the video frames (2300) represented by the image primitive node (2140) is composited with at least one further graphical primitive represented by at least one further primitive node (2130) of the compositing tree (2100). The video frame (2300) is composited with the further graphical primitive according to a compositing operation represented by an operation node of the compositing tree (2100) in order to generate a composite image (2303) represented by at least one composite node (2150) of the compositing tree (2100).

Abstract: Disclosed is a method of displaying a hierarchical file structure. The method determines a visual arrangement (100) of containers (102) which reflects a hierarchical relationship of the file structure. A concentric curved shape is then formed representing each container in the file structure and files within the containers, the curved shape having a geometry and location according to the determined visual arrangement. A viewpoint (600) is then established for the curved shape which is substantially radial thereto and allows viewing from a root container of the file structure towards one or more child containers of the file structure. The curved shape is then rendered, relative to the viewpoint, to a display (2114). Desirably, the files within a container (102) are represented as a tower (104) in the curved shape.

Abstract: The present invention relates to an adjustable clock skew apparatus and method for generating clock signals, which resolves the drawbacks of costing a user much time and effort to adjust clock skews of all components on a motherboard. In order to accomplish the object, the present invention proposes three operating modes: hardware setup, software setup or a mixture of hardward and software setup. A user just needs to adjust a plurality of exterior switches or to adjust a Basic Input Output System (BIOS) of the motherboard to modify the parameter of clock skew, and clock signals with necessary clock skews will be obtained.

Abstract: An implementation of a technology, described herein, for transmitting compressed network transport-layer-protocol headers in a speedy, efficient, inferentially synchronized, and robust manner. An implementation, described herein, models the transmission of compressed headers to the congestion procedure of the network transport-layer protocol (e.g., TCP's). Doing so, the sender of the compressed headers can infer whether the receiver correctly received them. Unlike the slow direct synchronization employed by conventional schemes, this implementation of the present claimed invention inferentially synchronizes by modeling after the congestion procedure of the network transport-layer protocol. This is inherently faster than direct synchronization. Since the implementation performs well over both noiseless and noisy links, it is particularly suited to use over wireless communications channels. This abstract itself is not intended to limit the scope of this patent.

Abstract: An automatic stable frequency detector and a method of finding a stable operating frequency in a computer system. The detector includes a central processing unit, a monitoring timer and a clock generator for providing a clocking frequency to the computer system. The method is capable of saving much user labor for calibrating the operating frequency of the motherboard of a personal or notebook computer. This is because personal or notebook manufacturers can set up the computer system to work at the highest stable operating frequency of whatever computer system through software or hardware.
