Upstream Signal Switching and Local Video Bus Switching

Whether switching from an upstream switcher or from the local ISS inputs, detection of loss
of sync and acquisition of the new signal on the video bus (Program or Preview) must be
managed properly to accomplish a pseudo seamless switch.
Select from the following options to customize how new inputs automatically transition to
the output when the signal is lost (see
command or the ISS 608 PCS Help File to configure):
Cut through black — The video in the window immediately mutes to black and cuts to
the new signal once it is applied (default).
Fade through black — The window freezes the last solid frame of the old signal and
fades down to black and fades the new signal on once it is applied.
Seamless cut — The window freezes the last solid frame of the old signal and
seamlessly cuts to the new signal once it is applied. If no signal is applied for 1 second,
the image within the window cuts to black.
Seamless fade — The window freezes the last solid frame of the old signal and
performs a seamless dissolve to the new signal once applied. If no signal is applied for
1 second, the image within the window fades to black.
Low Latency — The video in the window immediately mutes to black when the signal
is lost and cuts to the new signal once it is applied. A frame of video delay is removed
from the product video processing logic and may introduce video artifacts during the
upstream switch effect.
