Description - NRS70/NRS70TX

The NRS70 is a powerful frame-recursive noise
reducer. Designed for use in live broadcast and
post-production operations, it also provides an
economical pre-processing solution in DVD
authoring.

The NRS70 provides much improved performance
compared with adaptive technology. It
automatically eliminates almost all background
noise by a combination of techniques and filters.

A sophisticated motion detector seamlessly
switches off the noise reduction in moving picture
areas. A median filter is included to remove
impulse noise, and an additional sparkle filter can
be switched in constantly to provide extra noise
reduction with no compromise in picture quality.

In addition to noise reduction, the NRS70 also
provides multi-standard Y/C, composite and SDI
timebase correction and synchronization. The
composite input automatically detects PAL, NTSC,
NTSC-J, PAL-N, PAL-M, N4.43 and SECAM, and
is sampled and decoded using an adaptive comb
filter to ensure optimum decoding performance.

The signal correction features include RGB gamut
legalizer, luminance and chrominance gain, black
level, NTSC hue, vertical and horizontal
enhancers, Y-C horizontal timing and picture
position. Rugged sync and clock recovery ensure
reliable operation with unstable and noisy inputs.

Signals can be output as digital component SDI or
as broadcast quality composite. The 12-bit output
encoder is fully genlockable to a composite
reference and supports PAL, NTSC, NTSC-J,
PAL-N, PAL-M, N4.43 and SECAM. The NRS70
will also operate as a transcoder between any of
the available standards of the same line rate.

The NRS70 also has two separate AES inputs to
enable audio embedding into any of the eight pairs
of the SDI output. Individual channel routing is also
provided, along with two AES outputs.

Other features include freeze, pattern generation,
and GPI control / audio delay flag output. Full
RollCall remote control is available including
RollTrack for audio delay tracking.

Warning

Before installing a new module into the enclosure
the Configuration Rules given below must be
followed.

The rear of the enclosure must have a full
complement of rear panels. Any vacant slots must
have a blank rear panel fitted

Configuration Rules

These rules limit the total power dissipation of
modules that can be installed in the box. Use the
module power ratings to calculate the total power
dissipated in the enclosure.

Module Power Rating

The power rating for each module is given in its
associated operation manual.

Available Power

The Enclosure has 70 W of available power. The
power ratings of each module should be added
together and the total should not exceed 70 W.

◀ Input Standards

The decoder employs an auto standard detection
system. It will auto detect any of the standards that
are checked in the list of standards.

Input Standards

SDI 625
SDI 525
PAL
PALN

NTSC

PALM
N443

SECAM

NTSCJ

In the example above it will auto detect all
standards except NTSCJ. Any number (one or
more) of standards may be selected. For example,
in a given situation where it is known that only PAL
and NTSC input signals are expected, only the
PAL and NTSC standards should be checked.

The decoder will then only auto detect between
PAL and NTSC standards. Other standards will not
be decoded and will produce an unstable lock.

To force the unit to decode only one standard,
check that standard and uncheck all others.

Note that at least one standard must be selected; if
an attempt is made to uncheck all items the last
standard selected will remain checked and become
the only standard to be decoded.

For NTSC signals either NTSC or NTSCJ may be
checked, but it is not possible to check both NTSC
and NTSCJ.

The output line standard will be the same as the
detected input standard. i.e. the output signal will
be at a line rate of 625 if the detected input signal
has a line rate of 625; similarly the output signal
will be at a line rate of 525 if the detected input
signal has a line rate of 525.

NTSCJ When this function is enabled the decoder
will correctly process a NTSCJ signal (an NTSC
signal without pedestal).

Audio

There are 2 separate identical audio processing chains in the NRS70, Chain A and Chain B. The chain may be
set to either stereo or mono source routing mode.

Source Selection

Audio pairs can be routed using stereo mode or
alternatively each audio channel (subframe) can be
determined individually using mono routing mode
as shown above.

Processing

Gain Left and right separately adjustable by

±6 dB.

Invert Left and right separately to normal or

invert polarity signal.

Mute Left and right separately to mute or

pass signal.

Disable Left and right signals will both be

disabled.

Default Audio

If the audio source selected by the MUX is absent
the output will automatically default to the signal
selected in the Default Audio menu:

Tone The output will be the tone as set by the

Tone Setup function.

Silence The output will become Audio silence.

Disable The Default Audio function will be

disabled.

associated with edge-of-reception signals from
satellite feeds, impulse noise or drop-outs from
tape-recorded signals.

◀ Median Filter

Note that this function is only active when the
Sparkle filter is enabled.

When selected, sparkle concealment is enabled
that employs a threshold controlled 3-dimensional
median filter. This permits the removal of picture
disturbances that the normal sparkle detection
algorithm may miss. For example low-level
sparkles will be concealed. The Median filter is
particularly effective on very noisy sources. Note
that some loss of resolution may be observed
depending on the source material.

RollCall Control Templates for the NRS70

CONTROL

Input Select

This allows any of the 5 sources of video input
signal to be selected for processing.

Input Standard

The decoder employs an auto standard detection
system. It will auto detect any of the composite or
SDI standards that are checked in the list of Input
Standards.
In the example shown it will auto detect all
standards (including the SDI standards) except
NTSCJ. Any number (greater than one) of
standards may be selected.
For example, in a given situation where it is known
that only PAL and NTSC input signals are
expected, only the PAL and NTSC standards
should be checked.

The decoder will then only auto detect between
PAL and NTSC standards. Other standards will not
be decoded and will produce an unstable lock.
To force the unit to decode only one standard,
check that standard and uncheck all others.

Note that at least one standard must be selected; if
an attempt is made to uncheck all items the last
standard selected will remain checked and
become the only standard to be decoded.
Note also that for NTSC signals either NTSC or
NTSCJ may be checked but not NTSC and NTSC
Format J.

NTSC Format J

When this function is enabled the decoder will
correctly process a NTSCJ signal (an NTSC signal
without pedestal).

Freeze Input

When enabled the input signal will be frozen.

Default Output

If the input signal fails the output may be
configured to become one of the following:

Freeze

The output will become a frozen picture of the last
frame.

Black

The output will become a black picture.

Pattern

The output will become the test pattern as selected
from the Setup/Pattern menu.

Note that for this and other screens the following
applies:

The symbol represents the Preset function
and will return the function to the default setting.

The

an

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 of 0 for items on this screen.

This screen will allow the settings of the Chroma
Gain, Black Level, NTSC Hue, Luma Gain, Y/C
Timing and Picture position to be adjusted. AGC
and ACC may also be enabled.

Note that if the Proc Amp is enabled and settings
are not at their preset values the text UnCal will be
displayed in the Status display window.

Proc Amp Enable

Selecting the Proc Amp Enable function will
enable the settings of the Luma Gain, Black Level
and Chroma Gain functions.

Luminance Gain

By using the scroll bar the gain may be adjusted by
±6 dB in steps of 0.1 dB.

Selecting Preset returns the setting to the
calibrated value of 0.

Black Level

By using the scroll bar the pedestal may be
adjusted by ±100 mV in steps of 1 mV.

Selecting Preset returns the setting to the
calibrated value of 0.

Chroma Gain

By using the scroll bar the gain may be adjusted by
±3 dB in steps of 0.1 dB.

Selecting Preset returns the setting to the
calibrated value of 0.

RGB Legalizer Enable

When selected this will enable the RGB Gamut
legalizer. This will prevent the unit from producing
RGB signals greater than 101%.

Timing Enable

Selecting the Timing Enable function will enable
the settings of the Picture Position and YC Timing
functions.

Picture Position

This item allows the timing of the picture position
relative to the normal value, to be adjusted by
using the scroll bar.

Range is from ±592 ns in 148 ns steps.

Selecting Preset returns the setting to the preset
value of 0.

YC Timing

This item allows the timing of the chrominance
signal relative to the luminance signal, (i.e. Y to
Cb/Cr timing) to be adjusted by using the scroll
bar.

Range is from ±444 ns in 148 ns steps.

Selecting Preset returns the setting to the preset
value of 0.

Noise Reduction

This screen allows various forms of noise
reduction to be applied to the signal.

Noise Reduction

Noise Reduction Enable

When enabled the noise reduction system will be
active. Default is to Off

Y Noise Reduction

This item allows Recursive noise reduction to be
applied to the luminance channel.

The range of adjustment is off, low, medium and
high. Default is to Medium.

C Noise Reduction

This item allows Recursive noise reduction to be
applied to the chrominance channel.

The range of adjustment is off, low, medium and
high. Default is to Medium.

Recursive Threshold

This control sets the noise reduction threshold of
the recursive filters.

The range of adjustment is from Auto (0) to 7 units.
Preset is to Auto (0).

Note that applying a high threshold level may
assist with extremely noisy images; however this
may result in plain areas appearing flat.

Filters

Sparkle

Enabling this item applies a sparkle filter to the
signal, reducing the effect of sparkle noise
associated with edge-of-reception signals from
satellite feeds, impulse noise or drop-outs from
tape-recorded signals.

Median

When selected sparkle concealment is enabled
that employs a threshold controlled 3-dimensional
median filter. This permits the removal of picture
disturbances that the normal sparkle detection
algorithm may miss. For example low-level
sparkles will be concealed. The Median filter is
particularly effective on very noisy sources. Note
that some loss of resolution may be observed
depending on the source material.

Split Screen

This function allows the effects of noise reduction
to be easily seen by splitting the screen in half.
One half will show the picture with noise reduction
and the other half without noise reduction.

Off

This disables the split screen function.

Left-Right

When enabled, the screen will be split into two
equal sections separated by a vertical white line.
The processed picture will occupy the left hand
section of the screen and the unprocessed picture
will occupy the right hand side section.

Top-Bottom

When enabled, the screen will be split into two
equal sections separated by a horizontal white line.
The processed picture will occupy the bottom
section of the screen and the unprocessed picture
will occupy the top section.

To make the destination unit perform a particular
function a RollCall command number must be
entered using this function.

To add/change the number type the number in the

text area and then select (return).

(Preset) returns to the default number.

The Parameter has three sets of numbers. e.g.
100*001*000 (command 100 is memory recall and
parameter 001 means recall memory 1 on a
NRS70).

The first set (100) is the command or channel
number.

Note that channel numbers 14, 15, 16 & 17 should
be used for audio delay cards.

The second set represents the parameter. For
delay it is automatically inserted by the NRS70 and
represents the delay through the unit that is
communicated to an audio delay card.

The third set is the RollCall unit ID and it identifies
the board type. When the third set is not (000) the
RollCall ID has to match at the correct RollCall
address otherwise no action will take place.

(commtrol.exe), logserver (rolllog.exe) and logviewer (rollview.exe) programs.
On startup, the setup program prompts for an installation directory. The default installation directory is
C:\ROLLCALL. The set-up procedure will copy all the necessary files to this directory. Set-up will also create a
Windows Group called RollCall.
Depending on the product code of the diskette, Either two icons (RollCall and Commtrol for IQSPCR) or four
icons (RollCall, Commtrol, LogServer and LogViewer for IQSPCD) will appear in the group.

Overview

ROLLCALL.EXE:
This program allows control of RollCall compatible units. (IQ Modules, Supervisor, other S&W units with
RollCall gateway). Each unit has a ‘control template’ window for control of that device. The user can configure
the program for USER, ENGINEER or SUPERVISOR access levels with password protection. It can install
“template” files from new units automatically or by user request.

ROLLLOG.EXE:
This is the Log Server application that collects logging information from units on the network. Keeps a running
log file of every event received. Writes a current status file for configured units and allows the LogViewer
program to display the information.

ROLLVIEW.EXE:
This program displays the current status file written by ROLLLOG.EXE in a tabulated form. Coloured
conditions highlight warning and failure states. Can be configured for network access for remote monitoring
using share information from the LogServer program.

COMMTROL.EXE:
This program is called automatically by ROLLCALL.EXE or ROLLLOG.EXE and normally runs minimized.
Usually, there is no need to run this program by itself. This program provides the basic communications with
the PC card, serial comms ports or TCP/IP protocols. It also has monitoring facilities for data analysis.

SETUP Sub-Menus

These are selected by pressing the button adjacent
to the desired function.

Note that all these sub-menus include a SAVE
function which is used to save particular settings. If
the changed settings do not need to be saved use
the RETURN function to return to the previous
menu; this action will abandon any changes and
revert to the previously saved settings.

F/Panel Address

The address of this control panel will be displayed
as a 2-digit hexadecimal code.

Note that the code 0,0 effectively switches the unit
off from the network. The codes 0,1 to 0,F inclusive
are reserved for bridge addresses. Codes 1,0 to
F,F inclusive are available to the user.

The address code is user defined in the range 1,0
to F,F and is set by rotating the spinwheel to the
desired code and selecting the SAVE function.

F/Panel Name

The control panel may be given a name using this
function (e.g. Edit Suite, Studio 2 etc.) The
maximum number of characters, including spaces,
is 19 and may consist of letters and numbers
(ASCII Characters)
To edit the name press either the left or right hand
button adjacent to the arrows for the centre text
line until the character to be changed is flashing.
Using the spinwheel, scroll through to the
character required and then, using the left and right
hand buttons, select the next character; the other
characters may be changed in the same way.

When the name has been set to that required
press the SAVE function to save the name. Note
that to remove a character and leave a clear space
in the text line the Clear function (above Preset)
should be used. The Preset function returns the
text to the original data.

Auto Connect

The Auto Connect menu allows a number of units
to be automatically connected to the control panel
at power-up.

Up to 16 units may be designated in this way by
assigning a number to them (00 to 15).

Note that these numbers are also used to
assign the default unit.

The units in this list are (on power-up) in the

standby mode and although not currently active are
locked to this control panel and may not be
controlled by any other panel.

The unit name (second text line of the control
window display) may be displayed by scrolling
through the list using the button adjacent to the ì
arrow.

The network address of the unit is shown in the
third text line as three sets of hexadecimal codes.

The first set is the network address, the second set
is the physical unit address and the third set is the
port address. Each set of these codes may be
selected (the set will be shown enclosed in
brackets) by pressing the button adjacent to this
line.

The code may then be changed using the
spinwheel.

The code may be reset to 0000 00 00 by pressing
the clear button. This action also removes the unit
name from the display and inserts a ? symbol
indicating that no unit will be connected to this
session.

The Auto Connect set-up may be saved by
pressing either the dedicated front panel Save
button or by pressing the button adjacent to the
Save display text.
