XVP-3901 Up/Down/Cross Converter
3G/HD/SD Up/Down/Crossconverter with Optional Audio Processor
The award-winning XVP-3901 family from Grass Valley delivers all essential video and audio signal processing functions on a single module. It offers up/down/crossconversion with simultaneous 3G, HD and SD outputs. The XVP-3901 includes integral fiber I/O, full AFD support and background keying. Frame accurate Aspect Ratio Conversion (ARC) can be performed automatically, using embedded signaling based on the Active Format Description (AFD) standard.
