3.3.6.1.11 RESOLUTION
Either QCIF (Quarter CIF) with a resolution of 176 pixels per line and 144 lines
or CIF with 352 pixels per line and 288 lines can be selected. The setting only
becomes active if it is supported by the far end. If this is not the case, the units
“agree” to communicate with a resolution that is supported by both terminals
1
.
3.3.6.1.12 Flutter compensation - VIDEO RECORDER
If a video recorder is used as signal source instead of a camera, the TITAN
videocodec will not be able to synchronise with the recorder input signal (due
to the speed variation (flutter) of the recorder), unless the VIDEO INPUT
switch is set to RECORDER, in which case the flutter is compensated in the
videocodec.
If a camera is used, this switch should be set to OFF, in order to obtain the
best possible picture quality.
3.3.6.1.13 VIDEO INPUT: Colour or black/white camera
This switch setting is only important for a camera with CVBS (FBAS) output.
If a colour camera is being used, the switch should be set to FORCED CO-
LOUR. This ensures that even for a noisy signal (colour burst not always de-
tected) the colour remains in the picture.
In the AUTO DETECT setting, the colour burst is evaluated. If the colour burst
is detected, then colour is switched to. If not, the camera picture is processed
as a black/white picture.
1 At present, CIF is set as the resolution. If the far end terminal only has QCIF capability, then QCIF is used.
