Product Overview
provides one reference input signal, one HD/SD-SDI output
 Support selecting control mode between manual control and automatic
control
 The automatic mode performs based on signal analysis of video loss,
EDH, freeze frame, black burst and audio supervision.
 Build-in automatic horizontal corrector, and adjustable delay
 Detecting the trigger of alarm criteria for the control mode switch-over
 Support controls through remote control panel, GPIO and RS422
 Input IN1 bypass to the output in the event of power failure or module
missing
 The input cable equalization automatically
 Support clean switching technology
 Configures the modules through switches or network control panel
Functionality
 Alarms when video lost, static frame or detecting black field
 Supports power off memory, the settings will be restored if the module
loses power
 Provides frame synchronizer
 Supports intelligent protection function in order to avoiding "misuse".
When the input signal is detected abnormal, the switching operation for
output would be invalid.
