1 Scope
This second edition European Telecommunication Standard (ETS) specifies the data syntax to be used by
Videotex and Multimedia/Hypermedia Information retrieval services for implementation of the Videotex
Enhanced Man Machine Interface (VEMMI).
In the Videotex case this ETS is applicable to both the Videotex service and the attached Videotex
terminals. Those terminals may be connected to the Videotex service via the Public Switched Telephone
Network (PSTN), Integrated Services Digital Network (ISDN) or Packet Switched Public Data Network
(PSPDN). Typically, the terminals should support ISDN Syntax-Based Videotex (SBV).
The ETS can also be used for any kind of retrieval service (not related to Videotex) by using the relevant
underlying platform and content data types.
