    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: 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.

    摘要: Media fragmentation may be provided. First, a request for a manifest may be received from a client. Then, in response to the received request for the manifest, the manifest may be sent to the client. Next, a request may be received from the client for a file fragment. The request may indicate a start time and an end time corresponding to the file fragment. The request may be in a format defined by the manifest. Then a lookup table may be queried for a first byte location in a media file corresponding to the start time and a second byte location in the media file corresponding to the end time. Next, a portion of the media file between the first byte location and the second byte location may be extracted from the media file. The portion may comprise the file fragment. The file fragment may be sent to the client.

    摘要: Strategies are described for transmitting control information from a host module to a client module. The host module transmits the control information in-band along with a stream of media content information packets. The control information can be used to govern the operation of the client module. In one case, the control information alerts the client module to a discontinuity in streams, which may be the result of the user changing channels via the host or client module, etc., issuing a seek instruction, and so forth. Transmitting the control information in in-band fashion is advantageous because it reduces the need for complex linking between the control information and the associated content information.

    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: Strategies are described for coalescing the processing tasks associated with a series of control events that occur relatively close together in time. The coalescing can involve eliminating redundant tasks by more directly advancing to a terminal control state. One exemplary application of the control coalescing is in the playback of media content information in a networked environment. When a user enters a series of commands to repeatedly change the channel, or repeatedly seek new positions within a single stream, the control coalescing comes into play by aggregating these control events so that it requires fewer control processing tasks to perform. This provision helps reduce the latency associated with handling multiple control events that occur close together in time.

    摘要: An intelligent retransmission of data stream segments is disclosed. One embodiment comprises detecting a missing media data segment at a media receiver, assigning a value to the missing media data segment based upon media playback consequences of not utilizing the missing media data segment, comparing the value with a threshold, and requesting retransmission of the missing media data segment from a media server if the value meets a predetermined condition relative to the threshold. In this manner, retransmission is requested when it is determined that retransmission will improve playback performance relative to non-retransmission.
