Description
The FS400 family is a fourth generation
video scan converter. It accepts many
input resolutions and rates and converts
them to NTSC or PAL standards compliant
with SMPTE-170M and CCIR-656
standards. Also available as output
options are VGA 640 x 480 at 60Hz
progressive, SVGA 800 x 600 at 60Hz
progressive, and 100 Hz interlaced. The
chip has a programmable down scaler to fit
the incoming resolution to the output
display format. Within the FS400 are
capture and encoder engines separated by
the frame buffer memory controller.
Required external components are
minimal: a single 16M SDRAM memory,
clocks and passive parts.
Analog progressive RGB inputs are
digitized and converted to the YUV 4:2:2
format. Vertical scaling and flicker filtering
are implemented at the computer frame
rate ahead of the frame store interface.
Interlaced input is supported for XGA
resolution and above. In this mode, only
the first field is processed.
The Flicker Filter is an advanced 2
dimensional filter that enhances text
quality. Flicker Filter parameters are
programmable to allow user tradeoffs
between flicker and sharpness.
The FS400 family contains controls for
programmable sharpness, brightness,
contrast, and color saturation. These
controls allow output to be tuned to match
user desires and tastes.
Frame rate conversion is
implemented by a Frame Store
Controller that interfaces with an
external SDRAM frame store
memory.
YUV 4:2:2 data is recovered from
the memory at the outgoing frame
rate. Data is scaled prior to the
