HD1492 HD Encoder Frame Card
IN1 Master video input. Accepts SMPTE 259M
SD–SDI, SMPTE 292M HD–SDI, or SMPTE
424M 3G–Level-A SDI.
IN2 Auxiliary video input. Can be used as a
source of caption data when connected to a
captioned HD–SDI or SD–SDI video source.
Caption data from the Aux Video In will be
up-converted or down-converted as neces-
sary for encoding onto the Master Video
signal. If caption data is present at both the
Master Video In and the Aux Video In, the
signal with HD data will take precedence.

protection.
OUT2 Auxiliary video output with relay-bypass
protection.
