摘要： Methods and systems for protecting data that is intended for use and processed on video or graphics cards are described. In various embodiments, data that is intended for use by a video card can be encrypted such that any time the data is provided onto a bus (e.g. a PCI or AGP bus) between the video card and the computer system, the data is encrypted. For example, when data is moved from memory on the video card to the system's memory (e.g. when it is mapped to the system's physical memory) and vice versa, the data is in encrypted form and thus protected.

摘要： In a digital media pipeline, hardware-accelerated transform functions enable longer CPU idle time and a reduction in data transfer between the CPU and hardware, for the primary purpose of conserving power or increasing content security. Multiplexer/de-multiplexer functions can be configured as either stand-alone transform units or as plug-in components to a “pluggable” (host) media source or to a “pluggable” (host) media sink, so that the benefit of hardware acceleration can be applied to the source and sink as well as to the media foundation transform (MFT). Further data processing and control can be routed to a remote processing entity. The disclosed pluggable media source has a single input and one or more outputs; the pluggable media sink has one or more inputs and a single output. The pluggable media source and sink can be configured to accept plug-in components that support a wide range of data formats.

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： A video encoding acceleration service to increase one or more of the speed and quality of video encoding is described. The service acts as an intermediary between an arbitrary video encoder computer program application and arbitrary video acceleration hardware. The service receives one or more queries from the video encoder to identify implementation specifics of the video acceleration hardware. The service interfaces with the video acceleration hardware to obtain the implementation specifics. The service communicates the implementation specifics to the video encoder. The implementation specifics enable the video encoder to: (a) determine whether one or more of speed and quality of software encoding operations associated with the video encoder can be increased with implementation of a pipeline of one or more supported encoding pipeline configurations and capabilities, and (b) implement the pipeline by interfacing with the service.

摘要： Methods, systems and architectures for processing renderable digital content are described. The various embodiments can protect against unauthorized access or duplication of unprotected content (i.e. decrypted content) once the content has reached a rendering device such as a user's computer. A flexible framework includes an architecture that allows for general media sources to provide virtually any type of multimedia content to any suitably configured rendering device. Content can be protected and rendered locally and/or across networks such as the Internet. The various embodiments can provide a standard platform that can that can be leveraged to protect content across a wide variety of rendering environments, content types, and DRM techniques.

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： Techniques and tools for representing pixel data in a video processing or capture system are described. Described techniques and tools provide efficient color representation for video processing and capture, and provide flexibility for representing colors using different bit precisions and memory layouts. Described techniques and tools include video formats that can be used, for example, in hardware or software for capture, processing, and display purposes. In one aspect, chroma and luma information for a pixel in a video image is represented in a 16-bit fixed-point block of data having an integer and fractional components. Data can be easily converted from one representation to another (e.g., between 16-bit and 10-bit representations). In other aspects, formats for representing 8-, 10- and 16-bit video image data (e.g., packed and hybrid planar formats), and codes for indicating the formats, are described.

摘要： Systems and methods for interfacing media components are disclosed. Information about the capabilities of digital media components registered with the system is stored in a capabilities register. In addition, a profile register that contains information about specific capabilities required to perform specific tasks is developed. An application that requires digital media services can select one or more profiles representative of the required service from the profile register. The profile can be mapped onto the capabilities register to locate one or more digital media components registered with system capable of performing operations required to provide the digital media services. The components can be instantiated and connected to build a device capable of providing the requested digital media service. Also disclosed is an Application Programming Interface (API) that enables applications to interface with digital media components from disparate third-party vendors.
