- references to ITU-T Recommendation T.101, annex C for the use of Arabic, Hebrew and Chinese
character sets;
- references to ITU-T Recommendation T.52 for the use of the Cyrillic character set;
- the switching mechanism between Videotex terminal configurations.
The amendment specifies only additional aspects and contains no deletions to the current content of

Date of latest announcement of this ETS (doa): 31 January 1997

Amendments
Replace Part 0, subclause 1.2.2 (page 4) with the following text:
"1.2.2 Display structure
Videotex terminals shall use either the theoretical display structure (see subclause 1.2.2.1) or the time
dependent display order (see subclause 1.2.2.2).
1.2.2.1 Theoretical display structure
The theoretical sructure of the display consists of the following layers in order of precedence:
- alphamosaic character foreground and background layers (see part 1, section 1.2);
- photographic layer (see part 3);
- full screen background layer (see part 1);
- any other video source.
Changing the display structure is for further study.
1.2.2.2 Time dependent display order
The terminal structure can be regarded as a one layer display. The receiving order of the VPDEs
determines the display order; the last received VPDE, independent from its type, shall always be
processed and can be displayed. It may superimpose already displayed information."
