The DVB-8020B-S provides full frame synchronization and adjustable horizontal, vertical and continuously variable sub-pixel timing. These settings are protected in case of power failure. The DVB-8020B-S drives four serial digital outputs. Both 525 line and 625 line video formats are automatically supported. EDH and other ancillary data are passed through. The DVB-8020B-S processes SDI signals with full 10-bit accuracy. The output picture is synchronized to an external analog reference signal. Alternatively, it can be delayed relative to the input digital signal. In either case, the output timing is continuously variable on sub-pixel basis over full frame. The timing settings are maintained in the event of power failure.
