    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 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： 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： 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： Media streaming with smooth fast-forward and rewind is disclosed. One embodiment receives a media stream encoded at a first bit rate over a network connection, and in response to an input to fast-forward or rewind the media stream, the media stream may be retrieved at a second bit rate, and rendered at the second bit rate for fast-forward or rewind playback. By receiving the media stream at multiple bit rates, a media stream may be rendered at increased forward or reverse speeds without dropping frames in the media stream.

    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.
