Abstract: The present invention is directed to providing a method and system that enables a first responder police Incident Commander to take command and control of a building having an active suspect ongoing event. Using the method and system herein, the Police Incident Commander is able to clearly distinguish the positions of his building entry teams (BETs) in the building relative to the position of the suspect through a graphic display of Friend and Foe designation whereupon he can precisely direct their maneuver to close with the suspect. The incident commander communicates to a Command and Control Center to arm non-lethal chemical canisters pre-located in “Hot Zones” for use in remotely incapacitating the intruders. When the intruders, boxed in by the BETs, enter a “Hot Zone” the incident commander gives the command to release the non-lethal chemical/smoke, ammonia spray that disorients and blinds the intruders allowing the BETs to safely end the incident.

The first video signal processing chip determines whether both of a first video signal and a second video signal are in a stable state. After the first video signal processing chip determines that both of the first and second video signals are in the stable state, the first video signal processing chip sends a synchronization signal to the first video processing chip and the second video processing chip. After receiving the synchronization signal, the first video signal processing chip and the second video signal processing chip respectively output a first processed video signal and a second processed video signal to a display device.
