DIDON mediun
(see Fig.5)
Only data bytes are written into the FIFO memory. (In fast mode, information can be written into the FIFO memory only
after a page detection.)
DIDON short
(see Fig.6)
In this mode, format and data bytes are written into the FIFO memory. (In fast mode, information can be written into the
FIFIFO memory only after a page detection.)

NABTS
(see Fig.7)
In this mode, the continuity index, packet structure and data bytes are written into the FIFO memory. (In fast mode,
information can be written into the FIFO memory only after a page detection.)

U.K. teletext
(see Fig.8)
In this mode, the magazine and row address group (two bytes) and data bytes are written into the FIFO memory. (In fast
mode, information can be written into the FIFO memory only after a flag detection.)
