摘要： The present disclosure relates to playback of video/audio streaming media data to provide a substantially glitch-free experience. The system adapts the media stream to the user connection in order to choose the most desirable stream to avoid glitches. For example, in the case where there is interference (e.g., a microwave being used near a wireless device), the quality of the media stream is lowered. In one embodiment, an index file is used to make logical decisions about which media stream to choose in order to minimize glitches. The index file can take different forms, but, generally, includes characteristics about the available media streams. Example characteristics include the bit rates of the media streams and quality information about the media streams.

摘要： Program code enabling the streaming of HD content in real-time to a game console is stored on a storage medium remote from the game console. The game console executes software that facilitates transfer of the program code from the remote storage medium to the game console. The program code ensures that sufficient bandwidth exists on a network between the game console and a HD tuner, and enables the streaming of HD content in real-time to the game console.

摘要： A media processing framework includes multiple media processing paths. At least one of the media processing paths includes a media processing pipeline which is in-process with respect to an application which interacts with the media processing pipeline. At least one other of the media processing paths includes a media processing pipeline which is out-of-process with respect to the application. The application can specify a custom plug-in presenter module to be set in either the in-process media processing pipeline or the out-of-process media processing pipeline. The application need not be “aware” of the pipeline that is being used, whether the pipeline is in-process or out-of-process, or the security level that is applied to the media processing pipeline. Both the in-process and the out-of-process media processing pipelines can supply media information to a presentation processor, such as a compositing engine.

摘要翻译： 媒体处理框架包括多个媒体处理路径。 媒体处理路径中的至少一个包括相对于与媒体处理流水线相互作用的应用进行处理的媒体处理流水线。 媒体处理路径中的至少一个其他媒体处理路径包括相对于应用程序处理不成功的媒体处理流水线。 该应用程序可以指定要在进程内媒体处理流水线或流程外媒体处理流水线中设置的自定义插件演示模块。 应用程序不需要“意识到”正在使用的流水线，管道是在进程还是进程外，还是应用于媒体处理流水线的安全级别。 进程内和进程外的媒体处理流水线都可以向演示处理器（如合成引擎）提供媒体信息。

摘要： The present disclosure relates to playback of video/audio streaming media data with seamless advertisement insertion. A content player monitors playback of the media stream and determines a location to insert an advertisement. The content player pauses downloads of the media stream and begins downloading the advertisement while the media stream continues to be rendered. The advertisement is, consequently, loaded prior to a start time and allows for an instantaneous rendering at an advertisement insertion point in the media stream.

摘要： A client device receives streaming content from a host device. The streaming content is placed in one or more buffers prior to processing. Monitoring as to the capacity and fullness of the buffers is performed at the client device and information is sent to the host device. The host device adjusts the rate or flow of the streaming content based on the information provided by the client device.

摘要： Protecting elementary stream media content is described. In one aspect, Media Access Units (MAUs) of elementary stream content are identified. Each MAU includes one or more data segments representing a single video or audio frame. Encryption boundaries are selected for each MAU. The encryption boundaries are based on one or more data segments associated with the respective MAU. Portions of each MAU are encrypted based on corresponding encryption boundaries. Each MAU is mapped to a MAU Payload Format. The MAU Payload Format allows a media consumer to process each elementary stream associated with the elementary stream content independent of any different elementary stream. The MAU Payload Format also allows a media consumer to process each MAU in an elementary stream independent of any other MAU.

摘要： A digital media system uses client buffer fullness reports to detect clock drift between a clock on a host/source device that delivers streaming media content and a clock on a client playback device that receives the streaming media content. The system provides a reduction in playback interruptions during playback of streaming media content and a greater potential that “live” content encoded by a host/source device can actually be experienced as “live” content through playback on a client device.

摘要： A media experience policy engine includes three components: an information manager, a policy evaluator, and an enforcement module. The information manager collects information regarding the current state of a media delivery system, such as, for example, usage of a CPU, memory, hard disk, (I/O) interface, and a network. This collected data is then verified by the policy evaluator to see if resource contention is, or is close to, occurring. If so, existing or potential conflicts are dealt with by the enforcement module, which applies corrections, such as, for example, limiting the access of later chronologic users, or degrading the user experience of all users, in accordance with a desired policy in order to vitiate the resource contention and maintain a user experience consistent with the desired policy.
