Video Setup (Horizontal Lines Portray Video Sample)
Use this screen to select one of the video inputs and adjust the brightness, contrast,
saturation, and hue, if necessary. The user has the option to force the video image to
a certain mode (i.e., composite video or S-video if using the TPS-VIDL-1/TPS-VID-
1 or TPS-VIDL-2/TPS-VID-2 in S-video configuration) or switch modes
automatically after checking the image for colors. Use either the TP Composite /
BNC Composite or TP S-Video / BNC S-Video buttons to manually control the
mode. TP or BNC on the selected button specifies the video input connector. TP
corresponds to the twisted pair connector (balanced video from a PVID, Room Box,
etc.) and BNC corresponds to the BNC connectors (unbalanced video from a VCR,
DVD, etc.). Use the appropriate Auto Detect button for automatic control. The text
color of the selected button is red rather than black.
NOTE: When configuring the TPS-VIDL-2 or TPS-VID-2, the Video 1 signal type
can be automatically detected as long as one composite or S-video is sent to the
touchpanel. Auto Detect will not work when two composite signals present.
NOTE: Up to four composite video feeds can be physically connected to a
TPS-VIDL-2/TPS-VID-2 (two BNC feeds and two twisted-pair feeds). However,
only two composite video channels can be selected for viewing. Specify the
connections to use by selecting TP Composite, TP S-Video, BNC Composite, or
BNC S-Video for each channel. Additionally, the appropriate inputs must be
selected on the TPS-4500IMPC when using a TPS-4500. Refer to the
TPS-4500IMPC Interface Module Operations Guide (Doc. 6163) for details.
NOTE: A solid blue screen is displayed in the video window if a video signal is not
detected or is very weak. Verify that the video source is functioning and properly
connected. If the source is properly connected and functioning, a distribution
amplifier may need to be used.
Fast motion mode (if the Fast Motion button is selected) reduces motion artifacts
and should be used for most video sources. Still video mode (if the Still Video
button is selected) works best for still pictures. It has a maximum resolution and
reduces flicker. However, it suffers from motion artifacts. The text color of the
selected button is red rather than black.
Select the Soft button for soft mode video. In this mode, video filtering and noise
reduction can produce a better image from some sources. Alternatively, select the
Crestron TPS-4500 & TPS-4500L
