FUNCTIONAL DESCRIPTION
Acquisition area
The acquisition area is in the centre of the visible screen
area. Vertically 228 lines are sampled. Horizontally
672 Y-pixels are processed. The exact active processing
area can be fine tuned in horizontal (2 pixels/steps,
16 steps) and vertical (1 line/step, 16 steps) direction for
both main and sub-channel by the I
2
C-bus (see Fig.3). The
given numbers are pixel numbers at a 13.5 MHz data rate.
The signals, which are dependent on the I
2
C-bus registers,
can also be related to the H
sync
, in which event they are
delayed by 68 pixels.
Chrominance format
The chrominance format is 4 : 1 : 1.
The YUV signals are sampled at a rate of 27 MHz and then
filtered and subsampled to a data rate of 13.5 MHz.
It is expected that the input signals do not contain
frequencies outside the video bandwidth (Y
BW
= 4.5 MHz;
U
BW
and V
BW
= 1.125 MHz).
Display area
The display area is shown in Fig.4. The given numbers are
pixels at a data rate of 13.5 MHz. The signals are related
to the burstkey and the V
sync
. Dependent on the I
2
C-bus
registers the signals can also be related to the H
sync
.
The internal 13.5 MHz data rate is upsampled to the
double frequency (27 MHz) and then fed to the DACs.
The display output can be fine positioned by the I
2
C-bus in
64 steps of 4 pixels in horizontal direction and 64 steps of
1 line/field in vertical direction.
