Description
The GF9320 Scaling Processor offers 10 / 8-bit
broadcast quality scaling of video images up to 2048 by
2048 pixels. The GF9320 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 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.
