System Description
2.1
Display Modes
8 single- and 10 multi-PIP display modes are available. Decimation, memory controlling,
framing and on-screen display insertion depend on the selected display mode
(PIPMOD).
In the multi-PIP modes the complete inset picture can contain up to 9 partial pictures
(see diagrams below). One of the partial pictures shows a moving picture, whereas the
others show still pictures. The partial picture that has to be written is addressed via
I2C Bus. The addresses (WRPOS) for the individual pictures are shown in the diagrams.
The same addresses serve to choose the position of the moving picture. The multi-PIP
modes allow tuner scanning.
Four display modes are provided for applications with 16:9 inset signals or displays
(see table 1). The single-PIP display modes 15 and 18 can be used to display 4:3 inset
signals on 16:9 displays. To show 16:9 inset signals on 4:3 displays the single-PIP
display modes 16 and 19 have been added. By means of multi-PIP display mode 17
a POP picture on a 16:9 display can be created.
If a display mode is chosen that is not realized (modes 9, 12, and 20 to 31), the
PIP insertion is switched off automatically (PIPON = ‘0’).

The following diagrams show the various display modes. The figures on top of the
rectangles give the width of the complete inset picture in pixels whereas the figures on
the right specify its height by the number of lines. The values for the multi-PIP display
modes are obtained by adding the widths and heights of the partial pictures. The sizes
of the partial pictures correspond to the sizes of the inset pictures of the single-PIP
modes (see below).

Input Signal Processing
2.2.1
Data Transfer
The inset video signal is accepted as digital luminance and chrominance components
with a 13.5 MHz clock for the luminance signal and a 3.375 MHz clock for the
chrominance signals.
Inset synchronization is done via pin HSI for horizontal and pin VSI for vertical
synchronization. By analyzing the synchronization pulses the line standard of the inset
signal source is detected and interference noise on the vertical sync signal is removed.
For applications with fixed line standard (625 lines or 525 lines) the automatic detection
can be switched OFF.
The phase of the vertical sync pulse is programmable (VSIDEL) (see chapter 4.3). This
way a correct detection of the field number is possible, an important condition for frame
mode display.
2.2.2
Decimation Window
A window signal, derived from the sync pulses and the detected line standard, defines
the part of the active video area used for decimation. The window has a width of
576 pixels for the luminance signal and a width of 144 pixels for the chrominance
signals. In the vertical direction the window consists of 252 or 204 lines depending on
the line standard (625 or 525 lines respectively).
The horizontal position of this decimation window can be adapted to various applications
with the help of a programmable delay of the luminance signal (HSIDEL) relative to the
horizontal synchronization pulses. For HSIDEL = ‘0’ the decimation window is opened
0 clock periods (13.5 MHz) after the horizontal synchronization pulse. For the 625 lines
standard the 42th video line is the first decimated line, for the 525 lines standard
decimation starts in the 38th video line.

2.2.3
Decimation Filters
The input signal is decimated by subsampling with horizontal and vertical filtering. A
special antialias filter improves the frequency response of the luminance channel.
The following decimation filters are implemented:
Horizontal Decimation
Luminance Filter
Chrominance Filter

The realized chrominance filtering allows omitting the color decoder delay line for PAL
and SECAM demodulation if the color decoder supplies the same output voltages
independent of the kind of operation. In case of SECAM signals an amplification of the
chrominance signals by a factor of 2 is necessary because there is a signal only in every
second line. This chrominance amplification is programmable via I2C Bus (AMSEC).

PIP Field Memory
The on-chip memory has a capacity of 329184 bits. It stores one decimated field of the
inset picture. In the multi-PIP display modes the memory is able to store one decimated
field of every partial picture (e.g. during tuner scanning).
2.3.1

The picture size depends on the horizontal and vertical decimation factors.

2.3.2
Memory Writing
To get equal clock frequencies for luminance and chrominance signals a multiplexer at
the memory input generates a 3-bit data format for both chrominance components.
In field mode display only every second inset field is written into the memory, in frame
mode display the memory is written continuously. Data are written with the lower inset
clock frequency depending on the horizontal decimation factor (6.75 MHz, 4.5 MHz,
3.375 MHz, or 2.25 MHz).
Memory writing can be stopped by program (FREEZE), a freeze picture display results
(one field).
In single-PIP display modes frame mode display is possible having no scan conversion
and the same number of lines in inset and parent channel (625 lines or 525 lines both).
The result is a higher vertical and temporal resolution because of displaying every
incoming field. The standards are analyzed internally and an activated frame mode
display is switched to field mode display automatically when the described restrictions
are no longer valid.

2.3.3
Memory Reading and Synchronization to Parent Channel
The reading frequency is normally 13.5 MHz and 27 MHz for scan conversion systems.
For progressive scan conversion systems and HDTV displays a line doubling mode is
available (LINEDBL). Every line of the inset picture is read twice.
Synchronization of memory reading with the parent channel is achieved by processing
the parent horizontal and vertical synchronization signals. These signals are fed to the
IC at pin HSP for horizontal synchronization and at pin VSP for vertical synchronization.
A numerical PLL circuit generates a clock signal that is locked to the horizontal
synchronization pulses of the parent channel. The burst gate of the sandcastle signal
can be used for horizontal synchronization.
A field number detection is carried out for the inset channel as well as for the parent
channel. Depending on the phase difference between inset and parent signals a
correction of the display raster for the read out data is performed by omitting or inserting
lines when the read address counter outruns the write address counter.
2.4
Output Signal Processing
2.4.1
Display Position
The display position of the inset picture is freely programmable (POSHOR, POSVER).
The first possible picture position (without frame) is 55 clock periods (13.5 MHz or
27 MHz) after the horizontal and 7 lines after the vertical synchronization pulses.
Starting at this position the picture can be moved over the whole display area. Even POP
positions (Picture Outside Picture) can be used.
Note: Display without disturbances is only possible if the complete PIP picture is inside
the visible area of the picture tube

Line Standard of the PIP Picture
The line standard used to display the complete PIP picture is programmable via I2C Bus
(PIPLIN). The line standard of the parent channel or the inset channel can be used. In
addition a fixed line standard of 625 or 525 lines can be chosen.
Combinations of different line standards of the inset signal and the PIP display are
handled in a special way:
PIP display 625 lines, inset signal 525 lines
– The inset picture is shifted down by 12, 8, 6, or 4 lines according to picture size. Due
to this shift the centres of the inset pictures have the same position for both line
standards. The remaining 12, 8, 6, or 4 lines at the top and the bottom of the inset
picture are filled with the luminance value of the full screen background color (BCKY).
The chrominance values are set to ‘0’ for these parts of the inset picture.
PIP display 525 lines, inset signal 625 lines
– The inset picture is reduced to 102, 68, 51, or 34 lines. Depending on the number of
lines the first and the last 12, 8, 6, or 4 lines are omitted. In this way the display shows
the centre part of the original picture.
Displaying multi-PIP pictures this procedure is applied individually to each of the partial
pictures.
2.4.3
Interpolation of the Chrominance Signals
At the memory output the chrominance components are demultiplexed and linearly
interpolated to the luminance sampling rate.

Framing
In this part of the circuit a colored frame is added to the inset picture. 4096 frame colors
are programmable, 4 bits for each component Y, (B-Y), (R-Y). The horizontal and vertical
widths of the frame are independently programmable. In the multi-PIP modes the various
partial pictures are separated by inner frame elements. These parts of the frame have a
fixed horizontal width of 4 pixels and a fixed vertical width of 2 lines. For INFR = ‘0’ the
inner frame elements are not inserted.
The outer frame elements border on the inset picture without limiting its size whereas the
inner frame elements reduce the areas of the partial pictures.

Full Screen Background Insertion
Instead of showing the parent picture it is possible to fill the background (full screen
picture without inset picture and its frame, BCKON = ‘1’) with a programmable color.
For BCKFR = ‘1’ the background color is identical with the frame color, otherwise it is
defined by 6 bits programmable via I2C Bus: two bits for each component. The bits for
the chrominance signals are used directly as MSBs of the output words B-Y and R-Y.
The remaining LSBs are set to ‘0’. Therefore 16 different colors are possible. The two
bits for the Y-signal choose a luminance value according to the following table (100 IRE
corresponds to the full scale range of DAC input = integer value 63):

Filling PIP Picture with Color
The whole inset picture can be filled with the frame color (FRCOL = ‘1’) or the luminance
value for the full screen background insertion without colors (BCKCOL = ‘1’,
FRCOL = ‘0’). The frame elements remain visible. Filling the PIP picture with
background is especially useful before starting a tuner scanning cycle.
2.4.7
Wipe-In/Wipe-Out Facility
With the wipe-in/wipe-out function it is possible to make appear or disappear the
complete inset picture starting or ending at the lower right corner of the inset picture
position. Thereby the size of the picture is continuously increased and decreased
respectively. During this procedure the frame is shown with its chosen widths. 4 different
periods are programmable via I2C Bus.

chrominance signals (B-Y), (R-Y) or RGB signals.

2.4.10 Select Signal
For controlling an external fast switch (for example an RGB processor) a select signal
SEL is supplied. The delay of this signal relative to the luminance and chrominance
components is programmable for adaption to different external output signal

processings. Three different characteristics of the output stage of this signal are
available. An open source, an open drain, or a TTL output can be selected via I2C Bus
(SELMOD).
2.4.11 Blanking Signals
In case of full screen background insertion the circuit has to generate output signals with
correctly positioned line blanking intervals relative to the horizontal synchronization
pulses of the parent channel. This can be achieved by a programmable delay (BLKDEL).
A field-blanking interval with a length of 16 lines is also provided. It is triggered by the
vertical synchronization pulse of the parent channel (VSP). The generation of this
field-blanking signal can be activated via I2C Bus (VERBLK = ‘1’).
2.4.12 Pedestal for the Chrominance Signals
Both components of the chrominance signal are equipped with a programmable
pedestal (white balance, PEDESTU, PEDESTV). The pedestal values are fed to the
digital to analog converters during the line blanking intervals. For each component a 4-bit
value in 2’s complement code is defined via I2C Bus. Building up the 6-bit input words of
the digital to analog converters these 4 bits are used as LSBs. The missing two MSBs
are complemented by sign extension. In this way pedestal values from – 8 to + 7 LSBs
of the digital to analog converters can be achieved.
2.5
Digital-to-Analog Conversion
2.5.1
Analog Video Outputs
The IC includes three 6-bit digital to analog converters for the video outputs. Each
converter supplies a current through an external resistor that is placed between VSSA and
OUT1, OUT2, OUT3 respectively. The current is controlled by a digital control circuit.
2.5.2
Analog Control Signal
The additional 6-bit digital to analog converter that provides an analog control signal
(e.g. for color decoder adjustment) is fed directly by a 6-bit signal programmable via
I2C Bus. No external resistor is needed at output ANACON.
2.6
On-Screen Display
2.6.1
Display Format
The on-screen display allows to insert a block of 5 characters into each of the PIP
pictures. The characters are placed in a box (background) with a width of 64 pixels and
a height of 12 lines. This box is situated in the upper left corner of the PIP pictures. The
Semiconductor Group
27
03.96

background box can be made transparent (CHARBCK = ‘0’), i.e. behind the characters
the inset picture becomes visible.
64 different characters are stored in a character ROM (see table 2). Each character is
defined by a pixel matrix consisting of 10 lines and 12 pixels per line.
2.6.2
Character Programming
The 5 characters per block are programmable via I2C Bus using a 7-bit code which is
identical with the ASCII code except for some of the special characters. The codes are
placed in a character RAM consisting of 45 cells. The size of the RAM is determined by
the number of characters per block (5) and the maximum number of PIP pictures (9 in
multi-PIP display modes). The character codes can be transmitted in two ways: each of
the 45 RAM locations can be reached separately by its 7-bit address or the RAM can be
written consecutively starting at an arbitrarily chosen position. In this case the RAM
address is increased automatically.
The 7-bit address consists of two parts: the 4 MSBs are used to choose one of the partial
pictures and the 3 LSBs to select one of the 5 characters per block.

Numerical PLL
A numerical PLL circuit supplies a clock of about 27 MHz with high stability. The nominal
quartz frequency is 20.48 MHz. The generated clock is locked to the parent horizontal
synchronization pulses. Its frequency varies with the frequency of this signal. Four
different characteristics of the PLL behavior can be chosen to handle synchronization
signals from various sources (PLLTC).
If the PLL is switched OFF an external 13.5 or 27 MHz parent line locked clock can be
fed to the IC. Using up to three SDA 9189X ICs in the same application only one quartz
is necessary.
Note: Before setting bit D3 of subaddress 00 (READ27) noise reduction of the VSP
