信息技术 沉浸式媒体的编码表示 第8部分：网络基础媒体处理

[中文适用范围]： 基于网络的媒体处理（NBMP）框架定义了通过数字网络连接进行媒体处理的实体之间包括数据格式和应用程序编程接口（API）在内的接口。用户可以远程访问和配置操作，实现高效、智能的处理。本文档描述并管理应用于媒体数据的工作流程。此过程包括将媒体数据上传到网络、实例化媒体处理任务以及配置任务。该框架支持动态创建媒体处理管道，并且可以实时或延迟方式访问处理后的媒体数据和元数据。媒体处理管道中媒体源、工作流管理器和媒体处理实体之间使用的媒体和元数据格式也进行了规定。 [外文原描述]： The network-based media processing (NBMP) framework defines the interfaces including both data formats and application programming interfaces (APIs) among the entities connected through digital networks for media processing. Users can access and configure their operations remotely for efficient, intelligent processing. This document describes and manages workflows to be applied to the media data. This process includes uploading of media data to the network, instantiation of the media processing tasks, and configuration of the tasks. The framework enables dynamic creation of media processing pipelines, as well as access to processed media data and metadata in real-time or in a deferred way. The media and metadata formats used between the media source, workflow manager and media processing entities in a media processing pipeline are also specified.
