High Resolution Cameras—In the High Resolution Cameras
field, you can set each of the following graphics input devices to
4CIF (a video resolution standard) by selecting its
corresponding number where:
2 = Document Camera
3 = VCR
This option is not available for the primary (1) and secondary (4)
cameras because the higher resolution of 4CIF affects the frame
rate quality.
About 4CIF
Both the ViewStation FX and VS4000 support 4CIF, a video
resolution standard defined by 704 pixels per line and 576 lines per
video image. 4CIF resolution is four times higher than CIF (352
pixels per line and 288 lines per video image), a standard commonly
supported on video communications systems. With 4CIF, more data
is transmitted and processed, resulting in crisper images. 4CIF
should only be implemented on document cameras or VGA scan
converters and is not suggested nor supported for use in live video
mode.
4CIF only works between video communications systems
supporting this standard. If the receiving system does not support
4CIF, then the transmitting system does not send 4CIF data.
The VS4000 Camera Setup screen lets you set up options that are
specific to the VS4000 system.
