Video/S-video input card (Quantum Elite only)
The Video/S-video input card enables you connect up to 12 composite video sources,
S-video (YC) sources, or both types in combination. You can connect input devices to one
or both connectors via one or two of the provided breakout adapter cables.
The Quantum Elite 615 card frame can accommodate up to 14 Video/S-video input
cards, allowing up to 168 video source inputs. The Quantum Elite 408 and the Quantum
Connect card frames can each hold up to 7 video cards, allowing up to 84 inputs.
The Video/S-video input card performs the following:
•
Auto-detection of source types:
Full auto-detection is provided on each input.
NOTE:
PAL 60 format is not supported. PAL 60 is commonly output by European
VCRs when playing back an NTSC tape.
Automatic gain control (AGC) ensures optimum source display with signals as low as
20% of normal amplitude.
NOTE:
Due to the dynamic nature of AGC an identical source fed to different
inputs may not display with identical results.
•
Deinterlacing:
Sources that are connected to the Video/S-video input card are
interlaced scan and need to be converted to a progressive scan (deinterlaced).
•
Down-scaling of composite and S-video sources:
Independent horizontal and
vertical scaling is possible down to 1/16 of native resolution. For example, a source of
720x486 pixels can be scaled down to approximately 45x31 pixels.
More than one scaled version of each source is possible, subject to the maximum
number of sources supported by the scaler.
In the following table, “Real Time” refers to the number of windows that can be
created without any reduction in frame rate. “Absolute” refers to the maximum
number of windows that can be created.
