GF9320-E3

Product Summary

The GF9320-E3 Scaling Processor offers 10 / 8-bit broadcast quality scaling of video images up to 2048 by 2048 pixels. The GF9320-E3 supports arbitrary display modes to fit custom applications. Dynamic zoom and pan effects allow for a variety of aspect ratio conversion choices while a programmable colour background generator can be customized to appropriately match the image content. A fully programmable and flexible output matrix allows for colour difference over-sampling, gain and hue controls as well as YCbCr to RGB conversions to power nearly any display device on the market. The GF9320-E3 also includes a vertical interpolation filter to perform stand alone cost-sensitive de-interlacing. Broadcast quality de-interlacing is offered through a seamless interface to the GF9330 and GF9331 devices.
