Preliminary specification
Picture-In-Picture (PIP) controller
SAB9077H
FUNCTIONAL DESCRIPTION
Pixel rate
The internal chrominance format used is 4 : 1 : 1. It is
expected that the bandwidth of the input signals is limited
to 4.5 MHz for the Y input and 1.125 MHz for the U/V
inputs.
The Y input is sampled with a 1728
×
H
sync
(
≈
27.0 MHz)
clock and is filtered and down sampled to the internal
864
×
H
sync
(
≈
13.5 MHz) pixel rate.
The U and V inputs are multiplexed and sampled with a
432
×
H
sync
clock and down sampled to the internal
216
×
H
sync
(
≈
3.375 MHz) pixel rate.
Acquisition area
Synchronization is done via the acquisition H
Sync
and
V
Sync
pins. With the acquisition fine positioning added to a
system constant the starting point of the acquisition can be
controlled.
The acquisition area is 672 pixels/line and 228 lines/field
for NTSC and 276 lines/field for PAL. Both main and
sub-channel are equivalent in handling the data.
Display mode
The internal display pixel rate is 864
×
DPH
sync
which is
13.5 MHz. This pixel rate is upsampled by interpolation to
1728
×
DPH
sync
before the DAC stage.
Display area
The display background is an area of 696 pixels for both
PAL and NTSC, 238 lines for NTSC and 286 lines for PAL.
This can be put on/off by the BGON bit independent of the
PIPON bits. This area can be moved by the display
background fine positioning (BGHFP and BGVFP).
Its colour is determined by the BGCOL and BGBRT bits.
Within this area PIPs are defined dependent on the
PIP mode. The PIP sizes are determined by the display
reduction factors as is shown in Table 2. Whether a PAL or
NTSC fixed number is used is depends on the DPAL bit.
The display fine positioning determines the location of the
PIPs with respect to the background. sub and
main-channel both have their independent PIP size and
location control, which is shown in Fig.3.
