标准摘要
[中文适用范围]： 本文档规定了在 TPEG 服务中传递服务和网络信息的方法。 TPEG-SNI 应用程序旨在允许以高效、独立于语言的方式直接从服务提供商向最终用户传递有关另一个承载信道上相同服务的可用性的信息，或来自另一个服务提供商的类似服务数据。 本文档描述了许多信息表，这些信息表提供了用于描述服务、服务时间、内容、地理覆盖范围等的综合选项。 在所有 TPEG 流中，必须提供所谓的服务表指南 (GST) ）。 此外，可以用信号通知不同承载和服务之间的内容链接。 [外文原描述]： This document specifies the method for delivering service and network information within a TPEG service. The TPEG-SNI application is designed to allow the efficient, language-independent delivery of information about the availability of the same service on another bearer channel, or similar service data from another service provider, directly from service provider to end-users. A number of tables of information are described in this document which provide comprehensive options for describing services, their timing, content, geographical coverage, etc. In all TPEG streams, it is mandatory to deliver the so-called guide to the service table (GST).
