MFld and SFld
The number of fields stored in the VDRAM can be set with
the MFld and SFld bits. There is a limit of 4 Mbits which
can be stored. It is best to set these bits so that 3 fields
are stored for the sub channel and 2 for the main channel,
but this is not possible in all cases (large PIPs). Therefore,
the number of fields stored can be reduced. This can
result in some performance loss, e.g. if the sub channel is
set to 1 field joint line errors can appear.
IntOff, DNonInt, MNonInt and SNonInt
In automatic interlace mode (IntOff is logic 0) the device
calculateswhetherinterlacedornon-interlacedsignalsare
applied and acts accordingly. This can be overruled by
setting bit IntOff to logic 1. Bits DNonInt, MNonint and
SNonInt then determine the interlace. If the xNonInt bits
are set to logic 0 the device is put in interlaced mode, if
they are set to logic 1 the main, sub and/or display
channels are put in non-interlaced mode. DNonint
overrules MNonint (main and display channels are
coupled).
PalOff, DPal, MPal and SPal
In automatic mode (PalOff is logic 0) the device calculates
what type of signal is applied, PAL or NTSC. In the event
that the number of lines in a field is less than 287 it is
assumed to be NTSC, otherwise it is assumed to be PAL.
This can be overruled by setting PalOff to logic 1.
The xPal bits then determine the mode of the device. A
logic 0 sets the device in NTSC mode, a logic 1 to PAL
mode. DPAL overrules MPAL (main and display channels
are coupled).
PRIO, NipCoff, Fmt411, DFilt and Yth
The PRIO bit sets the priority between the main and sub
channels. A logic 0 gives priority to the sub channel which
means that the sub channel PIPs, if present, are placed on
top of the main PIP. A logic 1 places the main PIP on top
of the sub PIPs. The NiPCoff bit determines whether a
grey bar is inserted in case a NTSC PIP is displayed in a
PIP with PAL PIP size. The missing lines are equally
dividedbetweenthetoppartandthebottompartofthePIP
window and made 30% grey. If this bit is logic 0 the grey
bar is displayed, if this bit is logic 1 the grey bar is omitted
and the PIP data is shifted up. The Fmt411 bit sets the
YUV format. If this bit is logic 0 then the device is in
4 : 2 : 2 YUV mode, if this bit is logic 1 then the device is in
4 : 1 : 1 YUV mode. If the 4 : 2 : 2 format is used the
memory use is larger, so some modes are not available
and the length of a read/write cycle is larger. The Dfilt bit
controls an interpolating filter to expand the internal
720 pixels data rate to the output data rate of 2
×
720
pixels in 1FH mode. If DFilt is logic 1 then the filter is on.
The Yth
(3 : 0)
bits control the video output. If the current
Y value is less then Yth
×
16 then the fast blanking is
switched off, and the original live background will be
visible. This feature can be used to pick up sub-titles and
display them as OSD anywhere on the screen.
