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.
