DIDON ANTIOPE Teletext
The French teletext system Didon Antiope (Teletext system A) is mainly transmitted in
France in the SECAM L system.
As for teletext, the Antiope data are serially transmitted in the vertical blanking period in
lines that are not visible on the TV.
While coding of the transmitted text data in the teletext system B is closely related to the
structure of the TV signal (one text line is always sent during a TV line), this close con-
nection is not valid for the Antiope system. Start and stop of text pages and text lines are
controlled by additional paging and movement codes. Each page consists of 24 rows of 40
characters each (maximum). An additional page header (En-tĂȘte de page) may contain in-
formation such as page number, time, and date.
The Antiope information can be transmitted in lines 6 to 22 for the first field, and in lines
319 to 335 for the second field.
Fluke 54200 generates the Antiope signal in the lines 20, 21, and 333, 334. For further in-
formation about position and levels of a Didon Antiope data line, see Figure
