The 8950ADC converts a component analog
video signal from analog VTRs and switchers
to serial digital, which can then be routed
through a digital router or switcher, or stored
on a digital video disk recorder. It offers 2.5
horizontal lines of user-controllable delay to
adjust the output timing, and inserts EDH
code to help track errors downstream.
All possible adjustments to this card can be
performed directly on the module. When the
8900NET card is installed in the frame, you
gain immediate access to remote control and
monitoring.
