主　　题：TV tracking equipment moving analogy target C+ + language 

摘      要：Moving analogy target is a key component of the performance testing system in TV tracking equipment. A new method is provided to produce the moving analogy target whose motion speed, track, contrast and size can be varied. The video signal transformed by video switching card is used to test the performances of the electronic box of TV tracking equipment. These performances include minimal tracking contrast, minimal size of tracking target, maximal tracking speed and capture time.
