Background technology
With the development of the information-based command and control system of my army in recent years, military information command cars at different levels are filled extensively
Standby, accusing that in-car is general has 3-6 operation seat, and corresponding video signal source also has 3-6 individual even more many, it is sometimes desirable to by some
The information at operation seat such as High Resolution Ground Map, situation map are exported to large-screen display equipment, to provide directly perceived to commander
Human-computer interaction interface.
When commander need will wherein 1 tunnel signal source is inputted to large-screen display equipment when, conventional method need manually will
Each video signal source cable accesses large-screen display equipment manually.Or completed by external video switcher.External video switching
Device takes valuable charge interior space, and typically only has access 3-4 roads VGA signals, to access more way unlike signal kinds
The vision signal of class is just highly difficult.
The method that video signal source cable manually is accessed into large-screen display equipment takes time and effort, at present substantially not
Using.
