A.3.2 Method 2: Two Evertz Encoders
Figure A-3 depicts the typical wiring for two Evertz caption encoders to perform a VBI bridge function
for SDI video. Captions on both fields 1 and 2 are transferred in this manner.
Using the encoder's Engineering Setup Menu system, the user can configure serial port B into different
operating modes. Only serial port B supports these special modes. The encoder before the DVE
extracts caption data from the video and transmits it out of port B. The encoder after the DVE receives
caption data into port B and encodes this onto the SDI video passing through the unit.
