Preliminary specification
NTSC Picture-In-Picture (PIP) controller
SAB9080
MPIPON (
DOUBLE WINDOW
)
Bit MPIPON is used to switch the main channel PIP on
(logic 1) or off (logic 0).
SPIPON
Bit SPIPON is used to switch the subchannel PIPs on
(logic 1) or off (logic 0).
P
RIO
TheprioritybitdecideswhetherthemainchannelPIP(Prio
set to logic 0) or the subchannel PIP (Prio set to logic 1)
will be on top when both PIPs overlap.
S1FLD
If S1FLD is set to logic 0, two fields are used for the live
PIP. When a 50/60 Hz or a 60/50 Hz mode is detected, the
SAB9080 automatically switches to the 1-Field mode
(1-Field resolution vertically).
If S1FLD is set to logic 1, only one field is used. This
causes joint line errors but saves memory. This bit should
not be set in normal modes.
SF
REEZE
With SFreeze set to logic 1, the current live subchannel
PIP will be frozen. If set to logic 0, it is unfrozen.
A
LG
O
FF
In double window mode, precautions are taken to prevent
a joint line error. Under some conditions, this feature
should be switched off. This can be realized by setting this
bit to logic 1. Normally, bit AlgOff should be set to logic 0.
DN
ONINT
Innormalmode(thisbitislogic 0),theSAB9080calculates
whether a signal is non-interlaced and reacts accordingly.
With bit DNonint set to logic 1, the display channel is
forced into the non-interlaced mode. In the non-interlaced
mode, only one field is used during the processing of the
PIPs.

(
DOUBLE WINDOW
)
Bits SHRed<5:0> and SVRed<6:0> determine the
reduction factors in the double window mode.
The horizontal reduction is equal to SHRed/96; the vertical
reduction is equal to SVRed/96. SHRed should lie in the
range from 0 to 48; if set to logic 0, the PIP is off. SVRed
should lie in the range from 0 to 96; if set to logic 0, the PIP
is off.
When the horizontal reduction factor is 48/96),
704 samples are processed. The horizontal reduction is
linear; therefore, when it is 24/96, 352 samples are
processed.Thesameholdsfortheverticalreductionfactor

of processed lines can be calculated from

(
REPLAY
)
In replay mode, the ranges of SHRed and SVRed are
limited as follows: SHRed = 12; SVRed = 24, 16 or 12.
This leads to a fixed horizontal reduction factor of
1
8
; and
to a variable vertical reduction factor of
1

,
1
6
or

.
Note that the resulting replay PIP can be expanded by
using SHBlow and/or SVBlow.

FP AND
BGV
FP
These bits control the horizontal and vertical positioning of
the PIP configuration on the screen. The horizontal range
is adjustable in 16 steps of four 28 MHz clock periods.
The vertical range is 16 steps of 1 line/field.
The background colour can be adjusted with bits BSel,
SBBrt and SBCol.
SDH
FP AND
SDV
FP
These bytes control the horizontal and vertical positioning
of the subchannel PIPs on the screen. The horizontal
range is 256 steps of eight 28 MHz clock periods.
The vertical range is 256 steps of 1 line/field.

SAV
FP
Bits MAHfp<3:0>, bits SAHfp<3:0> and byte SAVfp
control the horizontal and vertical inset starting-points of
the acquired data. The horizontal range is 16 steps of
eight 28 MHz clock periods when SV2 is set to logic 1.
When SV2 is set to logic 0, the horizontal range is
