    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 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: 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.

    摘要: The present disclosure relates to playback of video/audio streaming media data. The media stream is available from the network at multiple bit rates. When a seek operation is performed, a playback device requests a lower bit rate media stream in order to quickly fill a playback buffer so that playback can commence more readily. After a seek start-up period is complete, the playback device can return to downloading the media stream associated with higher bit rates in order to increase the quality of the playback.

    摘要: An intelligent multi-sending of data stream segments is disclosed. One embodiment comprises monitoring one or more variable data transmission parameters, detecting one or more invariant media data segment parameters, assigning a value to the media data segment based upon the one or more invariant media data segment parameters and the one or more variable data transmission parameters, comparing the value to a threshold, and sending multiple copies of the media data segment over a network link to a media receiver if the value is above the threshold.

    摘要: A home entertainment network transmits audio/video decrypted from a DVD over a network to a media receiver using a secure channel. The A/V data is re-encrypted in a second encryption format amenable to transmission over the network. The media stream is thereby compliant with copy protection and digital rights management requirements. The media server constructs an emulated user interface corresponding to an actual instantiation of a navigation menu on the media server to solicit user input at the media receiver. The media server alternatively constructs a unique identifier of the DVD based upon the file structure on the DVD to search for menu navigation commands over an external network for heuristic navigation control.

    摘要: Defects and errors detected in media content supplied by a content source are corrected before the media content is delivered to a decoder. In one possible implementation, the detection and correction of defects and errors in the media content is conducted within a media stream analysis module. Correction of defects and errors may include the insertion, deletion or correction of headers, the insertion of broken link flags into the media content, the throttling of audio content in the media content versus video content in the media content, and the dropping of frames from the media content.
