Terminal Equipment (TE); Enhanced Man Machine Interface service for Videotex and Multimedia/Hypermedia retrieval services

The current ETS 300 382 can be used by dedicated videotex terminals and by PCs (Personal Computers). In order to make use of all possibilities of PCs, such as local storage, processing and GUIs (Graphical User Interfaces), ETS 300 382 will be extended. The aim is that all extensions should be upwards compatible. However, it is clear that some functionalities are specific to PC based terminals. The curent 7 bit coding needs to be extended to fulfill the functional requirements identified hereafter (bit maps, sound etc...). An enhanced coding (for 8 bit coding environments, possibly for 7 bit environments) providing compatibility with the existing one (upwards compatible profile mechanism, selection of an enhanced coding via 7 bit command,..) will be developed. Proposals for the extensions are already given in ETS 300 382, Annex B and TD51 (TE1 Chur (CH)). These include: Text attributes, bitmaps, other contents of the PC world, NDC dimensioning (further discussion necessary), local action management, local storage object, in text attributes, text box, operative object, set of object concepts.

1 Scope
This 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.
