5.4 IVT – Individual Video Tuning
IMPORTANT
When starting the CATVision system, the system executes automatically an
automatic adjustment of the video parameters (e. g. cable length, run time
delays to your environment and a video profil will be saved. As a result, the
displayed image on your screen should not need any further adjustments.
This saved videoprofil can be edited if the displayed image doesn´t meet your
exepectations. Therefore, the CATVision system offers the possibility of video
adjustment.
By this function the user can balance different cable qualities and lengths. The
individual characteristic of this function allows setting the measures to the
personal feeling for a “good picture”.
The adjustment is done via remote keyboard or as Supervisor from the
local console.
The system covers a range of 0 – 190; adjustment can be done in increments
of 1.
The CATVision system offers the possibility of selecting the kind of cable
used. Choose the corresponding mode for the kind of cable used most often.
As an option the run time delays of the CAT-x cables (Skew) can be balanced
with the delay electronically.
