Silicon Image, Inc. iScan Pro User Manual
15
- Insert just the Pr (red) signal into the Pr connector. This should result in a red picture.
- Remove the Pr and insert the Pb into the Pb connector. This should give you a blue picture.
- If one or the other of these combinations does not give the expected results, it may be a
problem with the output cable or the input connectors on the display. Try plugging the Pr
connector into the Pb input and verify that the video is blue. If it is, that means that the Pr
signal on the output cable is OK and the Pb input on the television is OK.
- Try the same with the Pb signal and the Pr input connector to verify the Pb cable
connection and the Pr input.
- Beyond this, we recommend that you contact your dealer for further technical support.
♦ Where can I get information to determine if the iScan Pro is a good match for my display
device?
The iScan Pro will provide superior decoding, deinterlacing, 3:2 pulldown detection, 2:2 pulldown
detection and motion compensation. However many display devices have poor quality scaling
which takes place after the iScan Pro processing, and may in fact degrade the video that will be
viewed.
♦ In addition to the iScan Pro, I also have an HDTV decoder. How do I hook them both up to
my TV set, which only has one YPrPb input?
There are a variety of high quality video switchers that are available for <$150. Most of these are
designed to allow the use of one computer monitor with more than one computer. We
recommend finding one that can handle at least SXGA type signals. These devices use a
standard female VGA connector for the display connection but sometimes use two male VGA
connectors to connect to the computers. Since the iScan has a female VGA connector, you
will need a VGA “Extender” cable, not a regular VGA cable to hook it up to the input of the
switcher.
This type of switcher could be used for either RGB or YPrPb type displays.
The iScan Pro was designed to operate continuously for many years. If you have any problems with
the unit, please call or visit the dealer where you purchased the iScan Pro. They will be happy to
assist you. Should your iScan Pro need repair or replacement, your dealer will be able to handle
that for you as well.
