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.
摘要翻译：描述媒体处理方法，系统和应用程序接口（API）。在一个实施例中，媒体引擎组件（也称为媒体引擎）提供了简单而统一的方式，可以将媒体从原始到目的地呈现，而不需要关于底层组件及其连接性和管理的亲密知识。媒体引擎的客户不必担心如何渲染特定的媒体，而只能专注于要呈现的媒体以及媒体的播放位置。在至少一个实施例中，媒体会话被提供并由媒体引擎封装，并且提供了一种机制，通过该机制使附加组件对于应用是透明的，并且在至少一些实施例中是媒体引擎。在一些实施例中，媒体引擎和媒体会话提供用于构建，配置和操纵组件流水线（例如，媒体源，变换和汇点）的简单API，用于在源和一个或多个目的地之间的媒体流控制。

摘要： The present automatic update mechanism provides a method for determining whether computer-readable components loaded within a memory device are at a level of protection specified for protected content that a media application is attempting to process. If a current level of protection provides lower protection that the level specified, a file is updated to achieve at least the level of protection specified by the protected content. Updating the file to achieve the level of protection is performed in a manner that minimizes rebooting of a computing device.
摘要翻译：本自动更新机制提供了一种用于确定加载在存储器设备内的计算机可读组件是否处于为媒体应用正在尝试处理的受保护内容指定的保护级别的方法。如果当前的保护级别对指定的级别提供较低的保护，则文件将被更新，以至少达到受保护内容指定的保护级别。以最小化计算设备的重新启动的方式来执行更新文件以实现保护级别。

摘要： An image container file has at least first and second multimedia streams (MSs). The first MS includes first image data representing an image. The second MS includes arbitrary data, which can for example, correspond to: a different representation of the same image; annotations to the first image data; second image data that together with the first image data form a new image with greater dynamic range, resolution, field of view or other attributes that can be derived from processing two or more independent images; or an executable file related to the first MS. The image container file can also include an extensible metadata to hold information describing one or more multimedia streams of the image container file. Further, the image container file may include DRM information to provide information related to obtaining a license to access encrypted data or verifying the authenticity of encrypted or unencrypted data.
