Abstract: A system is provided for synchronization between a host processor and a video interface having display terminal(s) and/or digital printer(s). The video interface is made self-adjusting with the reference synchronization signal of the video terminal which are provided by the host processor. A pixel clock in the video interface is recalibrated to a higher clocking rate and used for sampling the incoming data signals to identify the precise center of the data signals. The timing relationship betweeen the video interface clock signals and the host sync signals is then determined and stored, the resulting synchronization permitting the video data signals to be sampled in their precise center and thereby enhance the operation of the digital printer without manual intervention of service personnel.
