    • 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.
    • 一组接口和数据结构(即解复用器API)表示多媒体数据的解复用器。 数据结构使用多个字段,每个字段都包含命令的元素。 在一个实施例中,形成用于解复用器的正确操作的至少七个命令,包括Initialize,SetPresentationDescriptor,GetPresentationDescriptor,GetPendingPresentationDescriptor,ProcessInput,ProcessOutput和Flush命令。 解复用器API允许消费者以均匀的方式使用诸如DV的多路复用数据流数据来生成诸如音频和视频(压缩或未压缩)的基本流数据,并且允许解复用器被用作独立的组件。

    • 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.
    • 图像容器文件至少具有第一和第二多媒体流(MS)。 第一MS包括表示图像的第一图像数据。 第二MS包括任意数据,其可以例如对应于:相同图像的不同表示; 第一图像数据的注释; 第二图像数据与第一图像数据一起形成具有更大动态范围,分辨率,视场或可以从处理两个或更多个独立图像导出的其他属性的新图像; 或与第一MS相关的可执行文件。 图像容器文件还可以包括可扩展元数据,以保存描述图像容器文件的一个或多个多媒体流的信息。 此外,图像容器文件可以包括DRM信息,以提供与获得访问加密数据的许可相关的信息或验证加密或未加密数据的真实性的DRM信息。
