Bi Directional Colour Space Converter
Advance Information
DS3507 - 1.6 September 1996
DESCRIPTION
The VP510 converts three channels of RGB data into two
channels of decimated chrominance and luminance data.
Alternatively it converts two channels of luminance and chromi-
nance data into three channels of interpolated RGB data.
Each channel has its own RAM based look up table, which can
be loaded from a host system and then used for gamma
correction and/or ranging.
The direction of the data flow is controlled by a bit in a
Control Register, and causes previous outputs to become
inputs and vice versa. The filters change from the decimating
to the interpolating mode, and correspondingly follow or
precede the colour space conversion.
The 3 x 3 conversion matrix is provided with user definable
12 bit coefficients which have a range from -4.0 to +4.0. The
luminance channel is provided with a 23 tap low pass filter
which can decimate or interpolate by two. The chrominance
channels each have two 11 tap filters in series which can
decimate or interpolate by four. This arrangement allows the
device to accept or produce RGB data which has been 2x
oversampled, thus avoiding the need for external analog anti-
aliasing filters. If necessary the device will still accept or
produce video data which has not been oversampled.
