8990ARC
SDI aspect ratio converter
The 8990ARC addresses the need to
convert between standard and widescreen
formats resulting from various DTV standards
worldwide. Flexible aspect ratio control is
offered whether you’re starting with 4:3 or
16:9. GPI control allows the selection of
several predetermined aspect ratio modes
while local or remote control, via the Ethernet
interface, provides more complete aspect
ratio control. Additional control modes include
WSS widescreen signaling and video index
data embedded in the SDI video stream.
