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 method for video playback switching in response to changing network conditions. The method includes accessing a server to retrieve respective index files for a low bit rate version and a high bit rate version of the video file, and instantiating a low bit rate media player and a high bit rate media. Playback of the video file is begun by the high bit rate media player streaming the high bit rate version from the server. Upon an indication of impeded network conditions, a transition point is selected, wherein the transition point indicates where downloading of the high bit rate version stops and where downloading of the low bit rate version begins. The low bit rate media player is then positioned to begin playback at the transition point. Playback of the video file is then switched to the low bit rate player upon encountering the transition point.

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.
摘要翻译： 本文描述了媒体交互系统，其允许托管的应用程序消费和/或生成独立于媒体内容的格式的富媒体内容，同时仍保持主机的安全性。 媒体交互系统接受来自托管应用程序的原始未压缩媒体数据，并允许托管应用程序通过沙盒API提供自己的编解码器，该沙盒API将编解码器可以执行的操作限制在一组受信任的操作中。 然后，应用程序将未压缩的数据提供给系统进行播放。 因此，媒体交互系统以应用开发者支持的任何格式提供富媒体内容，并维护用户计算机系统的安全性。

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 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.
摘要翻译： 用于减少或消除在图像的颜色减少期间可能发生的伪影的方法和系统。 偏置被添加到被布置为存储图像的像素颜色的计数的数据结构。 图像的像素颜色的数量被添加到数据结构中。 通过数据结构，来自图像的颜色被分组到桶中，直到桶的数量小于或等于调色板中的多个颜色。 然后，图像中的像素的颜色被映射到调色板中的颜色。
