SD-7308

 - for switching between SDI sources: The machine is a multi-standard, adjustment-free 8x1 

switcher for SDI (serial digital) video signals.  It accepts up to eight SDI inputs, provides necessary 
buffering and reclocking, and routes the selected source to four identical SDI outputs using BNC 
connectors.  It provides automatic equalization for losses typical with long runs of 75-ohm co-axial 
cable.  Depending on the cable and video standard, cable length of several hundred meters is possible.  
Standard recognition is automatic and the machine switches during the vertical interval according to
