Setting RGB delay (computer video group only)
The switcher can briefly blank the red, green, and blue planes of a Computer Video
output while a tie is made to it. This allows a brief delay for the display to adjust
to the tied input’s sync timing before displaying the new picture, which will appear
without glitches. RGB delay, also known as Triple-Action Switching ™ or video
mute switching, is user selectable from 0 to 5 seconds, in half-second increments.
The RGB delay interval can be set on the front panel or by using the RS-232 and
Ethernet ports and either the SIS, Windows control program, or HTML pages (see
chapter 4, “SIS Programming and Control”, chapter 5, “Switcher Software”, and
chapter 6, “HTML operation”. Specify the RGB delay interval for a specific output
on the front panel as follows:
N
RGB delay is protected when front panel lock mode 2 is selected. You can view
the delay in lock mode 2, but not change it from the front panel. See “Setting
the front panel Locks ( Executive modes)” on page 3-44.
