8990ARC SDI Aspect Ratio Converter Key Features • SDI 270 Mb/s I/O • Operates at 50 and 59.94 Hz • Converts between 4:3 and 16:9 aspect ratios • Various aspect ratio modes with controllable crop location • Simple GPI remote control via BNC • Supports networked control and monitoring
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.
