IQDMSES Multi-standard Digital Encoder
Module Description
The IQDMSES is a full broadcast quality multi-
standard encoder. A 10-bit SDI input is encoded
into PAL, PAL-N or SECAM for 625 line inputs and
NTSC or PAL-M for 525 line inputs. A full frame
synchronizer and color frame accurate genlock
allows for simple installation.
Without a reference a minimum delay mode is
automatically selected. For maximum signal fidelity
the analog reconstruction uses a 12-bit 2 x
oversampled DAC. Standard VITS may be inserted
onto the output

CARD EDGE CONTROLS
Adjustment of the settings of the IQDMSES is available either via card edge controls and/or via a more
comprehensive remote control system using RollCall™
Note that the availability of some of the card edge controls will depend on the card version; see feature table
for variations.
LED INDICATORS
+5V and -5V
When illuminated these LED’s indicate that the
+5 V and -5 V supplies are present.
No Input
The No Input LED will be continuously illuminated
when the unit is not receiving an input signal.
Note that in the Genlock mode this LED will flash
when the input signal is of a different line standard
to that of the reference input. Under these
conditions the output signal standard will be the
same as the reference signal; the input signal will
be ignored.
No Ref
When the No Ref LED is illuminated this indicates
that the unit is not receiving a reference input signal.
Note that the No Input and No Ref LEDs will
flash alternately when the unit is configuring or re-
configuring in the event of a standard change.
The message Please wait.... will appear in the
lower line of the Information window during this
operation.

IQDMSES SECTION 11C
IQDMSESOPS 09/01/2008 www.snellwilcox Version 1 Issue 8 11c.8
EDH LEDs
EDH Present
This LED will be illuminated if EDH is present on
the serial input. In the event of an EDH error being
detected the EDH Present LED will become
extinguished and the EDH Sec and EDH Hour
LEDs will become appropriately illuminated.
EDH Sec
The EDH Sec LED be extinguished if no errors
have occurred during the previous second.
EDH Hour
The EDH Hour LED be extinguished if no errors
have occurred during the previous hour.
ScH Error/Delay Warning
This dual function LED warns of Genlock error
conditions.
It will be illuminated if ScH errors are detected in
the reference signal.
It will flash to warn that the delay through the
synchronizer exceeds 1 ms.
LINKS
Remote LK1
Note that the unit will respond to both local and
remote control, one system overriding the settings
of the other For cards using the RollCall™ remote
control system, activating the switches will
override the remote control settings. The
RollCall™control panel will then follow these
settings.
Note that in Main-frames where RollCall™ is not
available the link LK1 (Remote) should be set to
the OFF (unconnected) position. This ensures that
when the unit is powered-up the factory default
settings of parameters not available as card edge
adjustments, are loaded. With the link in the ON
(connected) position card will power-up with the
last settings sent by the remote control panel.

IQDMSES SECTION 11C
IQDMSESOPS 09/01/2008 www.snellwilcox Version 1 Issue 8 11c.9
SWITCHES
Two push buttons, a Hex switch and a 8 way DIL
switch allow various functions and modes to be
set.
The DIL switch selects a particular function and
the Hex switch selects a mode or variable
parameter.
The push buttons PB1, PB2 allow the value of the
selected function/parameter to be adjusted.
The Mode select switch may select a mode or a
parameter that may be adjusted.
Note that to select the preset value both
buttons should be pressed together.
FUNCTION AND MODE SELECTIONS
These switches allow the module to be operated
when an active front panel is not available.
All functions available via an active front panel are
duplicated by these switches.
More detailed information about these functions
will be found under MENU DETAILS starting on
page 11a.9
DIL SWITCH FUNCTIONS
Position 1
When set to ON (Down) This position allows the
encoder to produce a test pattern signal as an
output.
Positions 2 and 3
These positions are used to set the Genlock
Mode as shown in the table below:
(ON=Down, OFF=Up and X = don’t care)
PAL/NTSC operation
Mode Position 2 Position 3
Zero SC/H Lock OFF OFF
Internal Lock X ON
Or when SECAM operation is selected the
functions become as in the table below:
Function Position Selection
Bottles 2 UP=Bottles ON,
DOWN=Bottles OFF
Lock 3 UP=Locked to Reference
DOWN=Internal Lock
For detailed information on Genlock operation see
Appendix 1 on page 15
Position 4
This position allows the data in the vertical
interval of the input signal to be either passed
(OFF) to the output or blanked (ON) from the
output
Position 5
This position allows the limiter to set ON or OFF.
In the ON position the limiter will restrict the RGB
signal levels.
Positions 6 and 7
These positions allows the output standard of the
encoder to be set.
O/P Std. Position 6 Position 7
PAL-N/PAL-M ON OFF
PAL/ NTSC OFF OFF
SECAM/NTSC X ON
The output standard will reflect the operating line
standard; for example NTSC/PAL-M is only
available if the operating standard is 525 line.
The operating line standard will be determined by
the following detection method (in order of priority)
1. The reference input standard (signal input
standard ignored) when in Genlock mode.
2. If there is no reference signal, by the input
signal standard.
3. If there is no reference signal and no signal
input the standard may be selected by using
either the Mode Select switch or the Menu
system of an active front panel.
Note that to use this method of selection the
module must be operating in the Internal Lock
mode set by the DIL switch positions 2 and 3 or
via the Genlock menu.
Position 8 This position has no function at
present.

RollCall PC Control Panel Screens for the IQDMSES
Control
This screen allows various settings to be selected.
Standard
This item allows the operating standard of the unit
to be set.
The operating line standard will be determined by
the following detection method (in order of priority)
1. The reference input standard (signal input
standard ignored) when in Genlock mode
2. If there is no reference signal, by the input
signal standard.
3. If there is no reference signal and no signal
input the standard may be selected by using
this menu. This allows the module to provide
test signals in different standards.
Note that to use this method of selection the
module must be operating in the Internal Lock
mode set in the Genlock menu.
If the input standard as detected by either (1) or
(2) above is 625 line this will allow PAL, PAL-N or
SECAM to be selected as the output standard.
If the input standard as detected by either (1) or
(2) above is 525 line this will allow either NTSC or
PAL-M to be selected as the output standard.
If the signal input and reference input are of
different line standards, the unit will output a black
signal at the reference signal line rate.
EDH Statistics
The input stream is continuously monitored for
EDH errors. Basic information on this can be
monitored and/or reset here.
The following functions may be selected:
Show Stats
EDH errors will be displayed in the information
area.
Reset
The EDH error count will be reset to zero.

Control (continued)
Test Pattern
When checked, the selected test pattern via the
Test Patterns Screen will appear at the output.
Legalize Gamut
When checked this function prevents excessive
amplitudes of chrominance (out of Gamut) being
produced at the output.
This system will find the visually nearest allowed
colour in all circumstances. Normally this will
involve desaturation, so maintaining the same hue,
but where this is not possible (e.g. >100% yellow),
the luminance value will be modified to give a legal
visual approximation to the illegal colour.
Note that some contouring may be visible on the
corrected areas of the image.
The letters GAM will appear in the lower line of the
control window when this is enabled.
Insert VITS
When this function is checked the four standard
VITS lines are inserted in the vertical interval.
The letters VTS will appear in the lower line of the
control window when this is enabled.
Minimum Blanking
When checked the blanking width will be reduced
to the minimum allowed by CCIR 624.
Pass Vertical_Data
When checked (text reversed) the unit will
pass data (unblanked) present in the vertical
interval, to the output.
In 525 line standards all vertical interval lines from
11 and 274 onwards are unblanked with the
exception of the half lines 263 and 283. In 625 line
standards all vertical interval lines from 7 and 320
onwards are unblanked with the exception of the
half lines 23 and 623."
When unchecked (text normal) all data in the
vertical interval will be blanked.
When this item is checked the word PVD will
appear on the bottom line in the information
window.
NTSC Pedestal (for NTSC output only)
This function allows the pedestal to be ON
(included) or OFF (removed) from the output
signal.
When checked the output standard will be shown
as NTSC; when unselected it will show NTSC-J,
the version of NTSC used in Japan.
Note that after changing the NTSC_Pedestal
selection the output signal will be blanked for
about 5 seconds to allow for reconfiguration.
System I Blanking (PAL Output Standard only)
When this item is checked blanking will conform to
the System-I standard.
Pass Line 23
When checked the unit will pass the whole of line
23 (WSS line) in PAL & PAL-N standards.
When inactive only half of line 23 is passed in
accordance with CCIR-624.
Note that this control has no effect on 525 line
standards.

IQDMSES SECTION 11C
IQDMSESOPS 09/01/2008 www.snellwilcox Version 1 Issue 8 11c.13
Genlock
This screen allows various modes of genlock to be
enabled.
Note that for this and other screens the following
applies to the scroll bars:
The and symbols at the ends of the
scroll bar allow the value to be adjusted in discrete
steps.
The numerical value will be shown next to the
scroll bars and selecting Preset will return the
setting to the calibrated value for that item.
Genlock Modes
Internal
When this function is checked the output signal will
be locked to the serial input (if available) or
free-running if no serial input is available.
In this mode the frequency accuracy will be
±10 ppm
Notes:
1. This mode will be automatically enabled if the
signal input and reference input are of different
line standards and the output will default to
black burst in the reference standard.
2. This mode should be selected if test patterns of
a particular line standard (and different to the
reference input) are required at the output.
Zero SC/H Lock
In this mode the module locks to the reference
subcarrier and will always produce a zero ScH
(Subcarrier phase to H-Phase) output. The output
H timing will be maintained as close as possible to
the reference H timing in the correct colour frame.
The ScH warning LED will light if the ScH error of
the reference is > 20° (approx.), indicating that the
colour framing will be lost should the reference
ScH error increase.
Note that the output will always be 0° ScH phase
regardless of the reference ScH phase.
SC Phase
This function allows the relative phasing between
the reference subcarrier and the output signal
subcarrier to be adjusted. Rotating the spin-wheel
will adjust this value and the numerical display
shows the phasing in degrees.
The range of adjustment is 359.9° (continuously
adjustable) in steps of 0.1° and the preset value is
0° (Output coincident with reference)
Horizontal Phase
Selecting this item reveals a display showing the
horizontal timing of the output signal relative to the
reference sync signal, in nanoseconds. Rotating
the spin-wheel will adjust this value.
The range is approximately ±1.9 lines in steps of
one cycle of subcarrier. (This ensures the correct
SC/H timing is maintained)
Selecting Preset returns the setting to zero.
(Output coincident with reference)
SECAM Genlock
For SECAM the output will H phase to a PAL black
or black-burst reference; Db/Dr phase is such that
if the reference has a PAL burst, a V-Switch
(Phase = 135°) of burst on Line 1, Field 1 will
produce a Dr line in the encoded output.
If a SECAM reference signal is used the output
Db/Dr sequence will be locked to that of the
reference signal.

RollTrack
This function allows the value of the delay time
produced by this module to be sent, via the
RollCall™ network, to audio delay units connected
on the same network. This enables compatible
audio delay units to produce an audio delay
dependent on this and other similar units. The
audio delay unit will dynamically follow or track the
received delay-time information allowing
processed video signals to be timed correctly with
audio signals. This automatic tracking system via
the RollCall™ network is call RollTrack.
For more detailed information, see the RollTrack
section (Appendix) at the end of this manual.
The destination for the delay information is set by
the network code address as follows:
RollTrack allows up to 8 audio delays to be
selected as a destination.
Unit 1 Unit 2
Unit 3 Unit 4
Unit 5 Unit 6
Unit 7 Unit 8
The address of the selected destination unit may
be set by editing the text line.
To change the address, type the new destination
in the text area and then select (return)
(Preset) returns to the default destination.
The full network address has five sets of numbers.
For example: 0000:10:01*14*51
The first set (0000) is the network segment code
number
The second set (10) is the number identifying the
(enclosure/mainframe) unit
The third set (01) is the slot number in the unit
The fourth set (14) separated by an * is the
channel number.
Note that only channel numbers 14, 15, 16 & 17
should be used for audio delay cards.
The fifth set (51) is the board type identification.
Once a destination address for a unit has been set
the OK function will return to the unit menu to
allow another address to be set if required.
For more detailed information see the RollTrack
section of this manual.
