ABSTRACT:
Video interface for converting a video input signal of one format to a video signal of a second format. Microprocessor control system stores executable script commands, identifying parameters of an incoming video signal and a desired outgoing video signal. An input video template is created, replicating all the pulse events contained in an input video signal. The template is phase locked with the incoming video signal synchronizing an internal pixel clock with the active line period of the incoming video signal. A video output template is created from the executable script for defining an output video signal timing format. The microprocessor-based system provides for complete diversity in capturing an input video signal of one format and converting the same to a different format for display or copying by a peripheral device.
