Method and system for processing two analog composite video signals |
摘要 |
Disclosed is a method and apparatus for processing two analog composite video signals to be displayed to a human observer. The system includes at least a first and a second video source for generating first and second analog composite video signals respectively, and a selector coupled to the first and second video sources. The selector is operative to supply either the first or second analog composite video signal to one input of a video processor and independently and simultaneously supply either the first or second analog composite video signal to a second input of the video processor. The video processor is operative under control of a CPU to generate an output analog composite video signal comprised of a portion of the analog composite video signal supplied to the video processor's first input and a portion of the analog composite video signal supplied to the video processor's second input.
