信息技术 音视对象的编码 第6部分:交付多媒体的综合框架(DMIF)

[中文适用范围]： ISO/IEC 14496 的这一部分指定了 ISO/IEC 14496 的交付层，它允许应用程序透明地访问和查看多媒体流，无论流的源位于交互式远程终端系统上，流是否在广播媒体上可用或者它们位于存储介质上。 ISO/IEC 14496 的这一部分涵盖以下方面： DMIF 通信架构 DMIF 应用接口 (DAI) 定义 用于定位多媒体流并使其可用的 URL 语义 用于远程交互场景的 DMIF 默认信令协议 (DDSP) 及其使用现有本机网络信令协议的相关变体 用于播放器从广播媒体或存储媒体访问远程交互终端系统上的流的信息流。 [外文原描述]： This part of ISO/IEC 14496 specifies the Delivery Layer of ISO/IEC 14496, which allows applications to transparently access and view multimedia streams whether the source of the streams is located on an interactive remote end-system, the streams are available on broadcast media or they are on storage media. In this part of ISO/IEC 14496, the following aspects are covered: DMIF communication architecture DMIF-Application Interface (DAI) definition URL semantic to locate and make available the multimedia streams DMIF Default Signalling Protocol (DDSP) for remote interactive scenarios, and its related variations using existing native network signaling protocols Information flows for player access to streams on remote interactive end-systems, from broadcast media or from storage media
