3-13Integration Scaling Matrix Switcher • Operation
Auto Imaging and Auto Memories submenu
The Auto Imaging and Auto Memories submenu provides a means to turn the auto
imaging and auto presets features on or off for all input selections.
If auto imaging is set to on, the ISM automatically sizes and centers the selected
input to fill the screen when a new frequency is input. If auto imaging is set off, the
ISM sizes and centers the selected input only when it is commanded using the
input button, see Auto imaging an input, earlier in this chapter. Rotate the Adjust
knob to toggle auto imaging on or off for all input selections.
The auto memories feature saves and recalls centering and sizing information,
based on the input frequency. With some control systems, the delay involved in
recalling the memory can be a problem so it may improve system performance to
turn auto memories off. Rotate the Adjust
knob to toggle auto memories on or off
Enhanced Mode submenu
The Enhanced Mode submenu provides a means to turn enhanced mode on or off.
Enhanced mode is an automatic gain control for S-video or composite video input
signals scaled and applied to an output. If the input signal level is too weak, the
signal gain is increased; if the input signal level is strong, the signal gain is
decreased.
Use either the Adjust
or Adjust knob to turn on enhanced mode for neither
output (off for both), output 2, output 1, or both outputs. The default is Off.
Enhanced mode is only effective for S-video and composite video input signals.
Pixel Phase submenu
The Pixel Phase submenu displays and lets you set the pixel phase, which is the
timing of the digital scaler’s sampling. Sampling at the optimum pixel phase
results in a brighter scaled output.
Use the Adjust
knob to select the pixel phase for output 1 from 0 to 31. The
default is 16. Use the Adjust
knob to select the pixel phase for output 2.
PAL Film Mode submenu
The PAL Film Mode submenu lets you turn PAL film mode on and off for the
selected input. The PAL film mode should be used for a video source that is PAL
video that originated from film. PAL film mode applies video processing
algorithms that optimize the conversion of video that was made with the 2:2
pulldown (PAL video from film) process.
Use either the Adjust
knob or the Adjust knob to select On or Off. Select other
inputs as necessary to configure.
Reset submenu
The Reset submenu resets all ISM 482 settings and adjustments to the default
values and erases all presets. The front panel reset performs the identical functions
as the
Esc
zXXX SIS command (see chapter 4, Programmer’s Guide).
Reset the switcher by pressing and holding the Black/Mute button while this
submenu is active. The LCD displays Unit Reset to Factory Defaults when the
reset is complete. Release the Black/Mute button.
