摘要： A set of interfaces and data structures (i.e., a demultiplexer API) represents a demultiplexer of multimedia data. The data structure utilizes a number of fields, each containing an element of a command. In one embodiment, at least seven commands are formed for proper operation of the demultiplexer, including Initialize, SetPresentationDescriptor, GetPresentationDescriptor, GetPendingPresentationDescriptor, ProcessInput, ProcessOutput, and Flush commands. The demultiplexer API allows the consumer to use muxed stream data such as DV in a uniform manner to generate elementary stream data such as audio and video (compressed or uncompressed) and allows demultiplexers to be used as an independent component.

摘要： A computing system, which is in communication with a multimedia source and that includes at least one application for processing multimedia content from the multimedia source, includes an Application Programming Interface (API) for obtaining basic multimedia information that may be required by applications to process the multimedia content. By doing this, the invention enables multimedia application(s) to easily obtain the basic information from the API in a predetermined and standard manner, without having to obtain the information directly from the multimedia source, thereby reducing the functionality that has to be programmed directly into the application(s) for obtaining the basic information, and thereby reducing the cost, time, and resources that are required for creating the multimedia application(s).

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： A multimedia processing system and methods provide flexibility and modularity by separating data flow information from maintaining of stream state for multimedia components. The system includes a media processor component to process received media data, a media session to determine a timeline for events to occur for performing media processing and a topology loader component to load a topology that describes a flow for the received media data to enable processing via an extensible symbolic abstraction of media objects. The topology loader ensures that events described in the topology occur. The system also includes core layer components such as media sink components to determine a media stream for output from the multimedia processing system and a media source component coupled to supply media data for processing. The topology created in the system symbolically provides data flow information, independent of maintaining a streaming state of control information.

摘要： A method and system provides interfaces, data structures and events for representing a “sink” of multimedia data to interact with objects in a multimedia system to control multimedia objects. The interfaces and data structures enable efficient management for media objects that must interface directly with each other. One embodiment is directed to providing a common interface and a single API to a plurality of media objects. In an embodiment, the API is a control layer that isolates the media objects from each other and provides a single point of control, allowing media objects to be added or removed without affecting any other media objects. The control layer allows users to become familiar with only one API instead of many thereby facilitating the tasks of programming and documentation.

摘要： Media processing methods, systems and application program interfaces (APIs) are described. In but one embodiment, a media engine component, also referred to as a media engine, provides a simple and unified way of rendering media from an origin to a destination of choice without requiring intimate knowledge about the underlying components, their connectivity and management. Clients of the media engine need not worry about how to render the particular media, but rather can simply focus on what media to render and where to render the media. In at least one embodiment, a media session is provided and is encapsulated by the media engine and provides a mechanism by which additional components are made transparent to the application and, in at least some embodiment, the media engine. In some embodiments, the media engine and media session provide a simple API for building, configuring, and manipulating a pipeline of components (e.g. media sources, transforms, and sinks) for media flow control between an origin and one or more destinations.

摘要： A computer-implemented authentication protocol is used to subvert man-in-the-middle-type attacks on communications between software components that are permitted to interoperate within a processing environment, such as a media processing environment, pursuant to one or more licenses. In one exemplary scenario, a particular application transmits to a particular media processing component (“MPC”), among other things, a cryptographically protected message including a reference to a process in which the application is running and/or a GUID that the application used to invoke the MPC. If the received process and/or GUID are verified, it is possible for in-the-clear communication to occur between the application and the MPC without man-in-the-middle subversion.

摘要： Resource management architectures implemented in computer systems to manage resources are described. In one embodiment, a general architecture includes a resource manager and multiple resource providers that support one or more resource consumers such as a system component or application. Each provider is associated with a resource and acts as the manager for the resource when interfacing with the resource manager. The resource manager arbitrates access to the resources provided by the resource providers on behalf of the consumers. A policy manager sets various policies that are used by the resource manager to allocate resources. One policy is a priority-based policy that distinguishes among which applications and/or users have priority over others to use the resources. A resource consumer creates an “activity” at the resource manager and builds one or more “configurations” that describe various sets of preferred resources required to perform the activity. Each resource consumer can specify one or more configurations for each activity. If multiple configurations are specified, the resource consumer can rank them according to preference. This allows the resource consumers to be dynamically changed from one configuration to another as operating conditions change.
摘要翻译： 描述了在计算机系统中实现的管理资源的资源管理架构。 在一个实施例中，一般架构包括资源管理器和支持一个或多个资源消费者（诸如系统组件或应用程序）的多个资源提供者。 当与资源管理器进行接口时，每个提供者都与资源相关联并充当该资源的管理器。 资源管理员代表消费者对资源提供者提供的资源的访问进行仲裁。 策略管理器设置资源管理器使用的各种策略来分配资源。 一个策略是一个基于优先级的策略，区分哪些应用程序和/或用户优先于其他应用程序和/或用户来使用资源。 资源消费者在资源管理器中创建“活动”，并构建一个或多个描述执行活动所需的各种首选资源集的“配置”。 每个资源消费者可以为每个活动指定一个或多个配置。 如果指定了多个配置，资源消费者可以根据喜好对其进行排名。 这允许在操作条件改变时资源消费者从一个配置动态地改变另一个配置。

摘要： In a text display system facilitating the editing of text, smooth and flicker free updates to text displayed using proportionally spaced fonts are effected by interleaving the characters of an original and an updated text according to their associated cumulative character widths by sequentially storing each lesser cumulative character width and each character in buffers thereby establishing the order of display of the interleaved characters according to each original and updated cumulative character widths. The interleaved characters are then displayed according to the order of storage thereby incrementally displaying and deleting characters of the updated and original texts respectively such that an original character is deleted and replaced by an appropriate number of updated text characters resulting in a smooth text update.
摘要翻译： 在便于编辑文本的文本显示系统中，使用比例间隔的字体显示的文本的平滑和无闪烁的更新通过根据其相关联的累积字符宽度交错原始文本和更新的文本的字符来实现，顺序地存储每个较小的累积字符 宽度和每个字符，从而根据每个原始和更新的累积字符宽度建立交错字符的显示顺序。 然后根据存储顺序显示交错字符，从而分别逐渐地显示和删除更新和原始文本的字符，使得删除原始字符并将其替换为适当数量的更新的文本字符，导致平滑的文本更新。
