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.
