信息技术 - 多媒体应用格式（MPEG-A） - 第16部分:发布/订阅应用程序格式

[中文适用范围]： 本文档规定了使用发布/订阅 (PubSub) 通信模型进行多媒体通信的各方所使用的四种格式。PubSub 方包括：发布者、订阅者、匹配服务提供商 (MSP) 和消费者，所采用的格式包括资源信息 (RI)、发布信息 (PI)、订阅信息 (SI) 和通知信息 (NI)。本文档对 RI、PI、SI 和 NI 进行了规范，以支持典型的多媒体通信需求。以下是此类需求的非详尽列表。 [外文原描述]： ISO/IEC 23000-16:2018 specifies four formats that are used by parties communicating using the Publish/Subscribe (PubSub) communication model for their multimedia communication purposes. The PubSub parties are: Publisher, Subscriber, Match Service Provider (MSP) and Consumer and the formats employed are Resource Information (RI), Publication Information (PI), Subscription Information (SI) and Notification Information (NI). ISO/IEC 23000-16:2018 specifies RI, PI, SI and NI in such a way that typical multimedia communication requirements can be supported. The following is a non-exhaustive list of such requirements. - The Publisher can - describe the Resource for consumption purposes, - define the contract that will bind the Publisher and a Consumer, - request a device to report use of the Resource, - describe the Resource for distribution purposes, - define the contract that will bind the Publisher and a Match Service Provider (MSP) of a match involving the Publication, and - request the MSP to notify/not to notify a list of users. - The Subscriber can - query the Resource, - define the contract that will bind the Subscriber and a Match Service Provider (MSP), and - request the MSP to notify/not to notify a list of users of a match involving the Subscription. ISO/IEC 23000-16:2018 does not specify the protocols used to carry these payloads.
