Sync Type/Position
If OmniView is to be locked to reference syncs, select either (Analog) Sync (SD),
(Analog) Sync (HD) or Serial. SD sync signals are assumed to be bi-level, and HD sync
signals are assumed to be tri-level. If OmniView is not going to be locked to external
syncs, then select Free.
If the OmniTek system is used to look at an internally generated pattern, either using the
OmniGen line or zone pattern generation facilities, or using the OmniGen, or the
Motion/Capture option, to look at a stored image from disk, then it is possible to alter the
relative position of the output video with respect to the lock reference by adjusting the
horizontal and vertical offset controls.
However, if the OmniTek system is being used to look at a live video source, then the H
and V offset controls should both be left at zero, as no real timing control is possible for a
live video source. If OmniView is to be used to analyse incoming video, then it should
normally be synchronised to that incoming serial video.
Monitoring Output
OmniView provides an analog non-broadcast grade monitoring output, on a 9-way mini
din socket. The unit will be supplied with a breakout cable, which will either connect this
socket to an SVGA connector, or to 5 BNCs, depending on configuration at the time of
purchase. The video on this connector may be set to RGB or YPbPr, depending on the
Monitor Mode setting. Please note that if the monitor output is connected to an SVGA
monitor, then it will be necessary to use the RGB setting. Also note that in some
standards, there will be HD video on this connector, which will probably exceed the
bandwidth of cheap SVGA monitors. When the standard is set to NTSC or PAL, it is
possible to select Composite and Pedestal options for the monitor output. With the
standard BNC cable, the composite signal will be on the green BNC connector. In this
mode, there is also an S-Video output. The luma channel is on the red BNC, and the
chroma channel is on the blue BNC.
The green BNC will have tri-level sync on it.
Note that the analog output will run at the frame rate chosen for the video standard. It is
possible that some analog monitors will not be able to lock to some of the frame rates
that are available, in particular the very low rates used by the HDSL formats.
