The front-panel Genlock indicator provides the following information:
If the external sync reference is good, the Genlock indicator will light.
If the external sync reference is bad, the Genlock indicator will blink.
If the internal reference is selected, the Genlock indicator will not light.
Recording is not possible without an external Genlock reference.
Video Format
The Image Server is delivered in different models for NTSC or PAL. Files can only be played
by the machine model for which they were recorded.
Genlock Timing
Upon selecting the external sync reference, the video timing may be adjusted in terms of
lines (H sync) and pels (pixels) with reference to the external sync.
Color Framing
The Color Framing toggle setting allows all channels to achieve the correct color frame
sequence. Image Server's video channels are always correctly aligned with respect to each
other; however, after cycling power, color framing could be out of phase with reference to
the external genlock input. Color framing errors may appear as brief horizontal image shift
when switching between separate video sources.
NTSC Models: The Color Framing toggle button advances the phase of all channels by 180
degrees with respect to the external genlock signal.
PAL Models: The Color Framing toggle button advances the phase of all channels in 90
degree increments, with respect to the external genlock signal.
The Color Framing toggle setting is retained during a warm reset (i.e. by selecting "Reboot
Image Server" from the GUI Start menu), but is not restored after a cold shutdown (by either
selecting "Halt Image Server" from the GUI Start menu, or powering down the Image Server
by pressing the front panel power switch). In the case of a cold shutdown, Color Framing
may need to be toggled to properly align with the external genlock input.
The Color Framing toggle setting will have no visible effect when Video Sync is set to
Internal.
