The 8964ENC is a high-density, four-channel
module that converts four 270 Mb/s serial
component digital signals to four NTSC or
to four PAL composite analog outputs on a
single module. Typical applications include
cost-effective analog VTR interfaces, composite
analog production switcher inputs, and
analog transmitter feeds. Up to 40 encoders
can be housed in only 2 RU of space. Most
adjustments to this card can be performed
on the module's card-edge controls. The
on-screen display capability included with
each module greatly simplifies card-edge
configuration.
