Preliminary specification
Picture-in-Picture (PIP) controller for NTSC
SAB9075H
Table 5
Register 0; PIP mode control register
Notes
1.
With PIPON in OFF mode the fast blanking signal is made inactive. All other functions will operate as if the circuit
were in operational mode.
With MANRED set to logic 0 the reduction factors will be set automatically, dependent on the PIP mode and the
aspect ratio bits of main and sub (bits 5 and 4). Table 4 indicates which bits should be set to obtain a certain PIP
mode.
With MANRED set to logic 1 the calculation of the reduction factors is not carried out and should be set by Register 4
(see Table 9). Only combinations with MANRED set to logic 0 are guaranteed.
MASPECT and SASPECT are used in automatic mode (MANRED) to indicate the type of input signals, together with
MODE the PIP mode can be set (see Table 4). In manual mode these bits are ignored.
The MODE bits set the PIP mode. For the multi-PIP modes the frozen PIPs are set to the 30% grey colour. Once a
PIP has been made live it will always display the last video data.

Table 6
Register 1; general control register
Notes
1.
HPOS and VPOS determine the general location of the sub-PIP on the screen. HPOS only operates in modes SPS,
SPL, DP, MP3 and MP4. VPOS only operates in modes SPS and SPL. The default location of the sub-pictures will
be left top.
MFREEZE will freeze the main-picture, and SFREEZE will freeze the sub-picture selected by the live select bits as
in Register 8 (see Table 13).
BCOLPOL can invert the border polarity of U and V.
MVFILT and SVFILT set the type of vertical filtering for the main and sub-channel. Mode 1 means that diagonal lines
are linearized, in Mode 0 this option is switched OFF. This filtering mode only operates with vertical reduction
factors
