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： 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.

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： 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： 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.
