Module Description
The IQDEC02 provides a complete analog front-
end with 12-bit composite decoding,
synchronization and analog audio ingest in one
compact module. It is ideal for providing the bridge
between analog legacy operations and digital
environments. When paired with an upconverter
this module completes the bridge between analog
and HD domains. What makes the IQDEC02 so
powerful for these applications are its advanced 3-
D decoding algorithms employing updated
patented Golden Gate technology. These will
extract more original information from the analog
picture source than other decoders. This makes it
ideal for the transition from analog to digital or from
analog to HD. The IQDEC02 handles most
composite analog signal formats including PAL,
NTSC-M, NTSC-J, PALN, N4.43, PAL60, PALM
and SECAM. The full frame synchronizer with
horizontal and vertical phasing controls allows the
output to be timed to your house or studio
reference. In addition to its awesome video
performance, the IQDEC02 can digitize up to 4
channels of analog audio for both embedding into
the SDI stream and outputting as two AES
streams. What is more, an auxiliary SDI input is
included so that the IQDEC02 can be easily
integrated into mixed analog/digital environments.
Proc. amp controls and a powerful built-in noise
reducer complete the specification. The noise
reduction is targeted at preserving the original
content while eliminating the objectionable artifacts
of analog working. The noise reduction algorithms
are tuned to ensure optimum quality and lowest
bit-rates if the signal is subsequently compressed.

Select
This allows either the Composite A, Composite
B, YC or SDI input to be selected for processing.
Note that if the unit is de-embedding audio from an
SDI signal and then a composite or YC signal is
selected the unit will continue to de-embed and
output the audio from the SDI signal.
Input SDI Standard
This allows input standard for the SDI input to be
selected.
If only 625 is selected the unit will be forced to only
accept 625 line inputs.
If only 525 is selected the unit will be forced to only
accept 525 line inputs.
If 625 and 525 are selected the unit will accept
both 625 and 525 line inputs.
Composite/YC Color Standard
This allows the automatic detection of the color
standard(s) for the composite/YC input.
The module will automatically detect any of the
color standards that have been checked.
In the screen example above the unit will
automatically detect PAL, NTSC, PAL-M, PAL-N,
N4.43 60 and SECAM but will not detect NTSC-J
or PAL4.43 60.
Note that when selecting and deselecting SECAM
the output picture and audio may suffer some
disruption.
Freeze
When checked the output picture will become a
frozen frame.

Noise Reducer
This allows settings and adjustments to be made
to the noise reducer.
Delay Mode
This allows the delay of the noise reducer to be
selected.
Normal
In this mode the delay will be < 1 Frame
Minimum
This mode produces the minimum input/output
delay and may be used where audio delay
problems may exist and cannot be compensated
for. In this mode the delay will be < 3 Lines
Manual/Auto
Manual
In this mode the noise floor may be adjusted
manually using the Manual Noise Threshold
control.
Noise Measured
This provides an indication of how much noise
there is in the signal. A clean signal will give low
figures and a noisy signal high figures.
Auto
In this mode the noise floor is automatically
measured and the threshold is adjusted
dynamically set to an appropriate value for the
current input noise level. The noise detection
algorithm may be given a subjective bias using the
Auto Threshold Bias control to give more or less
noise reduction. Modification of the bias should not
be necessary under normal circumstances.
Luma Strength
This control changes the amount of noise
reduction for the luminance by limiting the
maximum level of noise reduction, where 31 is
maximum and 0 is minimum. Preset is to 0. The
actual level of noise reduction is dynamically
adjusted on a pixel-by-pixel basis with regard to
the noise reduction setting for the same pixel in the
previous frame.
Chroma Strength
This control changes the amount of noise
reduction for the chrominance by limiting the
maximum level of noise reduction, where 31 is
maximum and 0 is minimum. Preset is to 0. The
actual level of noise reduction is dynamically
adjusted on a pixel-by-pixel basis with regard to
the noise reduction setting for the same pixel in the
previous frame.

ProcAmp
These items allow various signal parameters to be
adjusted.
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 above the scroll
bars and selecting Preset will return the
setting to the calibrated value for that item.
Luma Gain
This allows the Y (luminance) gain to be adjusted
by ±6 dB in steps of 0.1 dB. Preset value is 0.0 dB.
Note that the maximum input level is +3 dB.
Black Level
This allows the black level to be adjusted by +120
mV in 0.5mV steps. Preset value is 0.
Chroma Gain
This allows the U/V (color difference) gain to be
adjusted by ±6 dB in steps of 0.1 dB. Preset value
is 0.0 dB.
Note that the maximum input level is +3 dB.
NTSC Hue
This item allows the Hue of an NTSC signal to be
adjusted.
The range of adjustment is ±45 degrees. Preset is
to 0 degrees.
Picture Position
This item allows the timing of the picture position
relative to the normal value, to be adjusted.
The timing may be adjusted by +592ns in 148ns
steps. Preset value is 0.
Y/C Timing
This item allows the timing of the chrominance
signal relative to the luminance signal to be
adjusted, (i.e. Y to Cb/Cr timing) in nanoseconds.
The timing may be adjusted by +592ns in 148ns
steps. Preset value is 0.

This allows the active picture to be blanked out or
cropped on each of the four sides.
Left/Right
The range of adjustment is from 0 to 200 pixels in
steps of 2 pixels. Preset is to 0 pixels.
Top/Bottom
The range of adjustment is from 0 to 200 lines.
Preset is to 0 lines.
The color of the blanked area may be set using the
Red, Blue and Green controls. The range of
adjustment is from 0 to 255 units. Preset is to 0, 0,
0 units (Black).
Enhance
This allows Vertical and Horizontal enhancement
to be applied to the picture.
V Enhance
This allows vertical enhancement to be applied to
the processed signal.
The level of enhancement may set to 0 (Off), 1
(Low), 2 (Medium) and 3 (High). Preset is to 0.
H Enhance
This allows Horizontal enhancement to be applied
to the processed signal. The non-linear process
prevents enhancement of low amplitude signals
typical of noise.
The level of enhancement may set to 0 (Off), 1
(Low), 2 (Medium) and 3 (High). Preset is to 0.
H Enhance Frequency
The frequency at which the horizontal
enhancement is applied may be set to either

Decoder
This screen allows the decoder functions to be set
up.
Decoder
This allows the type of decoding to selected.
Studio
▶This mode uses enhanced Golden Gate
technology. The composite input is sampled with
12-bit resolution and decoded using adaptive line
and frame comb filters to ensure optimum
decoding performance.
▶
Simple
This simple decode mode incorporates a wide
bandwidth subcarrier notch filter. This mode is for
reference only and should not be used for normal
composite material.
VHS/Unstable
In this mode the decoder will cope with sources
with unstable time-bases but the decoding is of a
lower quality and the frequency response is
reduced.
Note that in this mode the decoder will
automatically be set to Minimum Delay operation.
Color Killer
This function controls the color content of the
picture.
Chroma Off
When selected the color content of the picture will
be removed. The luma signal is produced using a
narrow bandwidth notch filter.
Chroma On
When selected the color content of the picture will be
maintained regardless of the level of the color burst.
Auto
When this item is enabled the picture will become
monochrome if the input color burst disappears or
the level drops below a critical amplitude. The
picture will return to color when the burst level
reappears.
Minimum Delay
This mode produces the minimum input/output
delay and may be used where audio delay
problems may exist and cannot be compensated
for. It uses the same adaption technique as the
Studio mode but has asymmetric frame stores.
