摘要: A system and method merges two or more analog video signals (Channels 1,2) under control of a third signal 154. standard output from one processor's digital to converter (DAC) is used as the for merging other signals. This enables outputs even highly diverse processing schemes be easily merged. In its preferred embodiment, includes switching circuitry (140-142) which mix different systems. The also (110) converts processor into large swing TTL switch.
