2.2. RGB Front-end
An analog RGB input port for an external RGB or YUV
source is available. The incoming signal is clamped to
the back porch by a clamping pulse. As the memory is
only able to store a 4:2:2 picture, the YUV input signal
is downconverted to 4:2:2. There are two operation
modes available. The first one uses this input as an
overlay input (soft mix). The RGB or YUV signal must
then be synchronized to the main CVBS/YC signal.
The second so called independent mode uses RGB /
YUV including sync or H/V signals. This can be used,
for example, for a DVD player or set-top-box. When
using H sync from a non CVBS input (e.g. separate H-
sync) this must be indicated by HINP. The usage of
separate V sync must be set by VINP.
The delay of luminance and fast-blank can be adjusted
by YFDEL, and chrominance can be delay adjusted by
UVDEL. If necessary, a fine adjustment of the fast
blank can be set by the parameter FBLDEL.
