TTX Processing:
[OFF, Video IN, Intern (ViTex)]
“OFF“
Feature deactivated.
“Video IN“
The teletext of the video input signal is converted to DVB compliant data packets and is transmitted in the TS.
“Intern“
With special additional software (Vitex), a separate teletext can be generated (functionality only available for SD video signals).
VPS-WSS-CC:
[OFF/ VPS/ WSS
/ VPS+WSS/ Closed Captions]
VPS and/ or WSS lines of the video input signal are converted to DVB compliant data packets and transmitted in the transport

Video Lines with TTX:
[0xFF87]
The lines used for the video text carousel being internally administered can be determined here in the vertical blanking inter-
val (VBI) of the video signal, the areas from line 7 to 22. The setting is bit by bit: “1” means “use”, “0” means “don’t use”. The
entries are hexadecimal; line 7 is equivalent to 0x8000, line 22 to 0x0001.
The standard line use is equivalent to the setting 0xFF87:

Table 3: configuration of the line use for teletext
Notes:
Lines 16 to 19 and 329 to 332 usually exclude teletext (kept as test lines). “0x” as a prefix indicates hexadecimal figures. A
calculator can be used for the calculation of the hex figure, for instance the calculator in Windows. For the [Bin] element, the
binary values 0 and 1 are entered in the desired order. When the display is switched over to hexadecimal [Hex], the hexadeci-
mal result will appear.
Status Pages in ViTex-TTX:
[ON(19x), OFF]
If the device is being used to manage its own videotext, status pages will be transmitted for service purposes, giving current
system states and messages, using pages 190 … 199. When the setting is “OFF”, all the status pages are suppressed. This
page range is available for conventional teletext tasks.
