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.

Reference Inputs
525 and 625
When suitable signals are connected to these
inputs, the video output of the unit will be fully
synchronised to the relevant signal source when the
genlock function is selected. There are separate
inputs for 525 and 625 line standard signals. If no
signal is present the unit will automatically revert to
internal free-running operation.
BNC loop-through connectors are provided and the
signal may be black burst or composite video at
standard level.

COMMUNICATIONS CONNECTORS
Remote
This 9 pin `D' connector on the rear panel allows
the unit to be connected to the RollCall 485 network
communications system. This connector may also
be used as a RS422 port. For more information see
Section 5 Modes of Operation.
RollCall
This single BNC connector allows the unit to be
connected to the RollCall network communications
system.
GPI I/O 1 and 2
These BNC connectors provide GPI input and
output control for the module.
Both GPI1 and GPI2 may be configured as inputs
that will allow memory locations to be recalled.
GPI2 may be configured as an output and will
provide an audio delay flag representing the video
delay through the unit.
