Digital video encoder (DENC2-SQ) SAA7187

FUNCTIONAL DESCRIPTION

The digital video encoder (DENC2-SQ) encodes digital
luminance and chrominance into analog CVBS and
simultaneously S-Video (Y/C) signals. NTSC-M and PAL
B/G standards also sub-standards are supported.

The basic encoder function consists of subcarrier
generation and colour modulation also insertion of
synchronization signals. Luminance and chrominance
signals are filtered in accordance with the standard
requirements RS-170-A and CCIR 624.

For ease of analog post filtering the signals are twice
oversampled with respect to pixel clock before
digital-to-analog conversion.

For total filter transfer characteristics see Figs 3 to 6 for
60 Hz field rate, and Figs 7 to 10 for 50 Hz field rate. The
DACs are realized with full 10-bit resolution. The encoder
provides three 8-bit wide data ports, that serve different
applications.

The VP1 port accepts 8 lines multiplexed Cb-Y-Cr data
(CCIR 656 mode), or Y data only (444 mode).

The VP2 port accepts Cr data in 444 input mode.
The VP3 port accepts Cb data (444 input mode) or

multiplexed Cb/Cr data (422 input mode). If not used for
video input data, it can alternatively also handle the data of
an 8-bit wide microprocessor interface.

Minimum suppression of output chrominance alias
components approximately 1 MHz due to high frequency
444 input is better than 12 dB.

The 8-bit multiplexed Cb-Y-Cr formats are CCIR 656
(D1 format) compatible, but the SAV, EAV, etc. codes are
not decoded.

A crystal-stable master clock (LLC) of 24.54 or 29.5 MHz,
which is twice the line-locked pixel clock, needs to be
supplied externally. Optionally, a crystal oscillator
input/output pair of pins and an on-chip clock driver is
provided. Additionally, a DMSD2 compatible clock
interface, using CREF (input or output) and RTC (see

“data sheet SAA7191B”

The DENC2-SQ synthesizes all necessary internal
signals, colour subcarrier frequency, and synchronization
signals, from that clock. DENC2-SQ can be timing master
or slave.

The IC also contains Closed Caption and Extended Data
Services Encoding (Line 21); it also supports OSD via
KEY and three-bit overlay techniques by a 24 × 8 LUT.

) is available.

The IC can be programmed via I
interface, but only one interface configuration can be
active at a time; if 422 or 444 input format is being used,
only the I2C-bus interface can be selected.

A number of possibilities are provided for setting of
different video parameters such as:

Black and blanking level control
Colour subcarrier frequency
Variable burst amplitude etc.

During reset (RESET = LOW) and after reset is released,
all digital I/O stages are set to input mode. A reset forces
the control interfaces to abort any running bus transfer and
to set register 3AH to contents 00H, register 61H to
contents 15H, and register 6CH to contents 00H. All other
control registers are not influenced by a reset.

Data manager

In the data manager, the demultiplexing scheme is chosen
in accordance with the input format.

Depending on hardware conditions (signals on pins KEY,
OSD2 to OSD0), and software programming either data
from the VP ports or from the OSD port are selected to be
encoded to CVBS and Y/C signals.

Optionally, the OSD colour look-up tables located in this
block, can be read out in a pre-defined sequence (8 steps
per active video line), achieving e.g. a colour bar test
pattern generator without need for an external data
source. The colour bar function is only under software
control.

Encoder

IDEO PATH

V
The encoder generates out of Y, U and V baseband

signals luminance and colour subcarrier output signals,
suitable for use as CVBS or separate Y/C signals.

Luminance is modified in gain and in offset (latter
programmable in a certain range to enable different black
level set-ups). After having been inserted a fixed
synchronization level, in accordance with standard
composite synchronization schemes, a variable blanking
level, programmable also in a certain range, is inserted.

Transients of both synchronization pulses and start/stop of
blanking are reduced compared to overall luminance
bandwidth.

C-bus or 8-bit MPU

1995 Sep 21 7

Philips Semiconductors Preliminary specification

Digital video encoder (DENC2-SQ) SAA7187

In order to enable easy analog post filtering, luminance is
interpolated from square pixel data rate to twice that rate
(24.54 or 29.5 MHz respectively), providing luminance in
10-bit resolution. For transfer characteristic of the
luminance interpolation filter see Figs 5 and 6 for 60 Hz
field rate and Figs 9 and 10 for 50 Hz field rate.

Chrominance is modified in gain (programmable
separately for U and V), standard dependent burst is
inserted, before baseband colour signals are interpolated
correctly to 24.54 or 29.5 MHz data rate. One of the
interpolation stages can be bypassed, thus providing a
higher colour bandwidth, which can be made use of for Y/C
output. For transfer characteristics of the chrominance
interpolation filter see Figs 3 and 4 for 60 Hz field rate and
Figs 7 and 8 for 50 Hz field rate.

The amplitude of inserted burst is programmable in a
certain range, suitable for standard signals and for special
effects. Behind the succeeding quadrature modulator,
colour in 10-bit resolution is provided on subcarrier.

The numeric ratio between Y and C outputs is in
accordance with set standards.

C

LOSED CAPTION ENCODER

Output interface

In the output interface encoded Y and C signals are
converted from digital-to-analog in 10-bit resolution both Y
and C signals are combined to a 10-bit CVBS signal, also;
in front of the summation point, the luminance signal can
optionally be fed through a further filter stage, suppressing
components in the range of subcarrier frequency. Thus, a
type of cross colour reduction is provided, which is useful
in a standard TV set with CVBS input.

Slopes of synchronization pulses are not affected with any
cross colour reduction active.

Three different filter characteristics or bypass are
available, see Fig.5 for 60 Hz field rate and Fig.9 for 50 Hz
field rate.

The CVBS output occurs with the same processing delay
as the Y and C outputs. Absolute amplitudes at the input
of the DAC for CVBS is reduced by15⁄16 with respect to Y
and C DACs to make maximum use of conversion ranges.

Outputs of all DACs can be set together via software
control to minimum output voltage for either purpose.

Synchronization

Using this circuit, data in accordance with the specification
of Closed Caption or Extended Data Service, delivered by
the control interface, can be encoded (Line 21). Two
dedicated pairs of bytes (two bytes per field), each pair
preceded by run-in clocks and framing code, are possible.

The actual line number where data is to be encoded in, can
be modified in a certain range.

Data clock frequency is in accordance with definition for
NTSC-M standard 32 times horizontal line frequency.

Data LOW at the output of the DACs corresponds to 0 IRE,
data HIGH at the output of the DACs corresponds to
approximately 50 IRE.

It is also possible to encode Closed Caption Data for 50 Hz
field frequencies at 32 times horizontal line frequency.

The synchronization of the DENC2-SQ is able to operate
in two modes; slave mode and master mode.

In the slave mode, the circuit accepts synchronization
pulses at the bidirectional RCV1 port. The timing and
trigger behaviour related to the video signal on VP ports
can be influenced by programming the polarity and on-chip
delay of RCV1. Active slope of RCV1 defines the vertical
phase and optionally the odd/even and colour frame phase
to be initialized, it can be also used to set the horizontal
phase.

If the horizontal phase is not be influenced by RCV1, a
horizontal pulse needs to be supplied at the RCV2 pin.
Timing and trigger behaviour can also be influenced for
RCV2.

1995 Sep 21 8

Philips Semiconductors Preliminary specification

Digital video encoder (DENC2-SQ) SAA7187

If there are missing pulses at RCV1 and/or RCV2, the time
base of DENC2-SQ runs free, thus an arbitrary number of
synchronization slopes may miss, but no additional pulses
(such with wrong phase) must occur.

If the vertical and horizontal phase is derived from RCV1,
RCV2 can be used for horizontal or composite blanking
input or output.

In the master mode, the time base of the circuit
continuously runs free. On the RCV1 port, the IC can
output:

• A Vertical Sync signal (VS) with 3 or 2.5 lines duration,
or

• An ODD/EVEN signal which is LOW in odd fields, or

• A field sequence signal (FSEQ) which is HIGH in the first

of 4 respectively 8 fields.

On the RCV2 port, the IC can provide a horizontal pulse
with programmable start and stop phase; this pulse can be
inhibited in the vertical blanking period to build up e.g. a
composite blanking signal.

The phase of the pulses output on RCV1 or RCV2 are
referenced to the VP ports, polarity of both signals is
selectable.

On the RCM1 port the same signals as on RCV1 (as
output) are available; on RCM2 the IC provides a
horizontal pulse with programmable start and stop phase.

The length of a field also start and end of its active part can
be programmed. The active part of a field always starts at
the beginning of a line.

Control interface

DENC2-SQ contains two control interfaces: an I

2

C-bus
slave transceiver and 8-bit parallel microprocessor
interface. The interfaces cannot be used simultaneously.

The I2C-bus interface is a standard slave transceiver,
supporting 7-bit slave addresses and 100 kbits/s
guaranteed transfer rate. It uses 8-bit subaddressing with
an auto-increment function. All registers are write only,
except one readable status byte.

2

C-bus slave addresses can be selected

Two I
(pin SEL_MPU must be LOW):

88H: LOW at pin 61
8CH: HIGH at pin 61.

The parallel interface is defined by:

D7 to D0 data bus
CS active-LOW chip select signal
RW read/not write signal, LOW for a write cycle
DTACK 680xx style data acknowledge (handshake),

active-LOW
A0 register select, LOW selects address, HIGH selects

data.

The parallel interface uses two registers, one
auto-incremental containing the current address of a
control register (equals subaddress with I2C-bus control),
one containing actual data. The currently addressed
register is mapped to the corresponding control register.

The status byte can be read optionally via a read access
to the address register, no other read access is provided.

Input levels and formats

DENC2-SQ expects digital YUV data with levels (digital
codes) in accordance with CCIR 601.

Deviating amplitudes of the colour difference signals can
be compensated by independent gain control setting,
while gain for luminance is set to predefined values,
distinguishable for 7.5 IRE set-up or without set-up.

Reference levels are measured with a colour bar,
100% white, 100% amplitude and 100% saturation.

When the IC is operating with input data in accordance
with CCIR 656, programming can be carried out
alternatively via the parallel interface using VP3 port for
data transfer.

For other input modes, the I

2

C-bus interface has to be

used for programming.
