progressive images using interlaced I/O
double banked control registers for 'on-the-fly' dynamic
effects
external 3:2 / 2:2 pull-down insertion and extraction
programmable output matrix with 6dB gain range

fully programmable colour background generator
flexible F,V,H output and TRS insertion
seamless interface to GF9330 de-interlacer
seamless interface to common SDRAM

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.
