摘要： A method and system for reducing or eliminating artifacts that may occur during color reduction of images. A bias is added to a data structure that is arranged to store counts of pixel colors of an image. Counts of pixel colors of the image are added to the data structure. Via the data structure, colors from the image are grouped into buckets until the number of buckets is less than or equal to a number of colors in a palette. Then, colors of pixels in the image are mapped to colors in the palette.

摘要： Described is a technology by which code, such as an untrusted web application hosted in a browser, provides content through an interface for playback by an application environment, such as an application environment running in a browser plug-in. Content may be in the form of elementary video, audio and/or script streams. The content is in a container that is unpackaged by the application code, whereby the content may be packaged in any format that the application understands, and/or or come from any source from which the application can download the container. An application environment component such as a platform-level media element receives information from an application that informs the application environment that the application is to provide media stream data for playback. The application environment requests media stream data (e.g., samples) from the application, receives them as processed by the application, and provides the requested media stream data for playback.

摘要： A media interaction system is described herein that allows hosted applications to consume and/or produce rich media content independent of the format of the media content, while still maintaining the security of the host. The media interaction system accepts raw, uncompressed media data from a hosted application, and allows the hosted application to provide its own codec through a sandboxed API that restricts the actions the codec can perform to a set of trusted actions. Then, the application provides the uncompressed data to the system for playback. Thus, the media interaction system provides rich media content in any format that the application developer supports, and maintains the security of the user's computer system.

摘要： The values of each possible component output R, G, and B may be pre-computed for all values of each possible component input Y, U, and V. Each contribution of Y, U, and V input may then be loaded into a register and added in parallel, without overflow, resulting in a computationally inexpensive RGB output from a YUV input. In one embodiment, contributions of Y, U, and V to each of R, G, and B are retrieved from pre-computed tables. The YUV contributions for each value of R, G, and B are packed into three data elements and added together in parallel, resulting in a value for an RGB output.

摘要： Described is the multiplexing and de-multiplexing of graphics streams, including by generating first higher-level graphics instructions from a first application program upon connecting to a client computer. A first identifier representing the first application program is associated with the first higher-level graphics instructions. Second higher-level graphics instructions are generated from a second application program, with a second identifier representing the second application program associated with the second higher-level graphics instructions. The first higher-level graphics instructions and the second higher-level graphics instructions are sent to the client computer. A server computer thus allows one or more application programs to be accessed by a client computer. The server includes a compositor that extracts higher-level graphics commands from one of the application programs, along with a remote display driver that packages the higher-level graphics commands for use by the client computer to generate graphics.

摘要： A method and system for color correction in composite image. Spill in a foreground image can be keyed directly to produce a spill matte that can be displayed to a user. The user can apply suitable image processing to the spill matte to modify the eventual color correction to the composite image. The resulting spill matte is used as a template for the application of color correction in the composite image.
