摘要： This disclosure describes methods, systems, and programming interfaces for more efficiently processing media data in a media pipeline. In one embodiment, media flow in a media system is coordinated using a media foundation transform supported by a programming interface. The programming interface generates input and output events to the requisite media system thereby permitting the media foundation transform control over when input frames are requested and received and output frames are retrieved.

摘要： A system and methods provide handling of variable rate playback in a multimedia computer architecture. The systems and methods provide data structures and interfaces that enable a computer architecture and components therein with the ability to playback data at speeds faster and slower than real-time, to playback data in reverse, and to change the rate of playback at any point during playback. One embodiment is a method for providing low-latency, glitch-free changes in a multimedia architecture. Other embodiments are directed to defining multimedia component responsibilities for making rate changes, allowing rate changes to work with standard playback types, coder-decoders, and renderers. The methods include determining a minimum of the maximum reported playback rates and determining minimum and maximum playback rates in a set of modes including: reverse skip mode, reverse key frame mode, reverse full mode, forward full mode, forward key frame mode, and forward skip mode.

摘要： Methods, systems, and computer program products for arbitrarily indexing multimedia content. In accordance with example embodiments, a multimedia content stream that comprises one or more samples is received. At least one of the samples is passed to one or more multimedia filters for analysis based on criteria that define an index type for the multimedia filter. Once it is determined that the sample meets the criteria for an arbitrary filter and index type, an index entry that identifies both the sample and the index type of the arbitrary filter is created. The index entry is adapted in accordance with a common, extensible indexing scheme to coexist with other index entries of other or the same index type for the sample. The created index entry is stored for subsequent access.

摘要： Strategies are described for processing image information using a data structure which conveys color information. The color information describes color-related formatting applied to the image information. The data structure can be passed down a video processing pipeline, where each functional component in the pipeline can draw color information from the data structure to improve the accuracy of its processing. Further, each component can supply previously unknown color information to the data structure for use by other (downstream) components in the pipeline. Exemplary fields of the data structure can include one or more of: a video transfer function field; a color primaries field; an image light field; a transfer matrix field; a nominal range field; and a video chroma sampling field. The transfer matrix field can be used to convert image information from one color space to another, such as a luma-related color space to an RGB-related color space. Processing operations can be performed on progressive and linear RGB image information.

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： Methods and systems are provided for synchronizing various time-stamped data streams. The data streams can be synchronized to another data stream or to a point of reference such as a reference clock. In one embodiment, synchronization processing takes place in association with a filter graph comprising multiple filters. The filter graph is configured to process multiple timestamped data streams for rendering the data streams in accordance with data stream timestamps. A synchronization module is provided and is associated with the filter graph queries individual filters of the, filter graph to ascertain input timestamp-to-output timestamp mappings. The module computes adjustments that are to be made to output timestamps in order to synchronize the data streams, and then instructs queried filters to adjust their output timestamps in accordance with its adjustment computations.

摘要： Methods and systems for protecting data that is intended for use and processed on video or graphics cards are described. In one embodiment, data is provided into a first portion of memory on a video card and the first portion has a first level of protection. The data is operated upon to provide resultant data on the video card. A determination is made as to whether a second portion of the memory on the video card has a level of protection that is compatible with the first level of protection. If the first and second levels of protection are compatible, the resultant data is provided into the second portion of the memory on the video card.

摘要： Methods and systems for protecting data that is intended for use and processed on video or graphics cards are described. In one embodiment, data that is stored in memory other than a video card memory is encrypted and transferred over a bus to the video card. The encrypted data is decrypted on the video card independent of a graphics processor unit (GPU) on the card needing to process the encrypted data. The decrypted data is stored in the video card memory.
