Intelligent transport systems — Traffic and travel information (TTI) via transport protocol experts group, generation 2 (TPEG2) — Part 9: Service and network information (TPEG2-SNI)

Scope

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). Additionally, it is possible to signal linkage of content between different bearers and services.
