Broadcast Test and Measurement Update cont'd...
The Lindos MS20

Lindos' MiniSonic MS20 is a
combined audio oscillator and
measuring set in a mains/batterypowered unit. Equipped with a stereo
PPM, a bidirectional balancedunbalanced converter, a stereo
microphone pre-amp, a headphone
amplifier and a level converter, it also
doubles as a line-up tool. Automated
measurements can be made using
Lindos' sequence testing with results
presented on the integral OLED display
or an attached PC. Phase, frequency
and phase response, noise, distortion,
crosstalk, path latency, headroom
and wow & flutter can be measured.
The MS20 has a 4 Hz to 40 kHz
digitally synthesised generator and
a +19 dBu balanced output. Windows
support software Lin4Win is included,
providing a control panel which
displays both channels on large bar
graphs as well as digital readouts to
0.01 dB resolution.
PHABRIX' QxL 25G IP rasterizer
is designed to address the needs
of broadcast media IP networks.
It supports JT-NM TR 1001-1:2018,
2110-20 (video), 2110-30 (PCM audio),
2110-31 (AES transport), and 2110-40
(ANC media) flows all with 2022-7
Seamless IP Protection Switching
(SIPS), and independent PTP slaves on
both media ports for fully-redundant
media network operation. The toolset
also provides support for the Dynamic
Host Configuration protocol on all IP
ports, unicast DNS-SD, AMWA NMOS
IS-04 Discovery and Registration, IS05 Connection management, system
resource, and Network Topology
Discovery using Link Layer Discovery
protocol. IP media interfaces are
provided as standard and SDI media
interfaces with optional SDI eye and

PHABRIX's QxL

jitter measurement
are available as a
factory fitted option.
The GUI provides
up to 16 userconfigurable windows with presets for
rapid visualisation of different traffic
and workflow configurations. The user
interface is the same as the Qx. ST
2110 and NMOS details are presented
in an intuitive and accessible manner.
Operator-level IP flow health and PTP
monitoring features are provided,
including warnings and alarms. An IPMEAS tool-set provides engineeringgrade information including four
2022-7 Packet Interval Time displays
and media port network statistics.
" The QxL provides an intuitive toolset
for full operational flexibility and easy
migration from an SDI to an IP-centric
operation, with unparalleled priceperformance, " summarises CEO Phillip
Adams.
Rohde & Schwarz' BTC (Broadcast
Test Centre) is a reference signal
generator with analysis functions
and the ability to perform automated
tests of audio, video and multimedia
devices, including support for DVB-S2X
and ATSC 3.0. It generates RF signals
for all global broadcasting standards,
performs transmission simulation and,
at the same time, makes audio and
video analyses for the device under
test.
Shootview's Magnum Engineer is a 1
RU test pattern generator supporting
20 video display resolutions ranging
from 480i60 and 576i50 to 1080i50
and 1080i60. Operators can select
between 40 test signals, including a
moving zone plate. Additional features
include lip sync test, VITC generation,
audio tone generation and keyboardentered idents. Up to four lines of text
can be overlaid on a selected pattern,
input via a standard PS2 keyboard.
Spectral Measurement (formerly
Prism Sound) offers dScope Series
III audio testing software including a
relatively new hardware
interface, the dScope
M1. The M1 series
comprises
several
units in a range of
options including wide

bandwidth with maximum
sampling rate of 768 kHz.
This allows measurement
from DC to >200 kHz as
well as lower residual
THD+N (typically <-110dB)
for amplitudes up to 100
volts RMS. The M1 unit
now has a phantom power
option allowing direct connection
of measurement microphones. This
comes with tools for measurement of
electroacoustic devices. Capabilities
include impulse response analysis and
logarithmic sine generator sweeps.
The dScope Series III M1 system
runs standard audio tests such as
frequency response and distortion
measurement. Auto Sequence enables
serial execution of saved test setups.
including
customisable
prompts
between setups and automated
collection of results to Microsoft
Excel spreadsheet, plus automated
generation of HTML test reports. The
user interface is based on standard
tools such as signal generator,
voltmeters, FFT and sweep responses.
Telestream's Cloud Stream Monitor
service is a combination of capabilities
based
around
live
streaming,
workflow, cloud, integrated monitoring
and containers. It can be used to select
one or more cloud data centres and
to specify the types of monitoring
probes that customers want to push
into those data centers. A monitoring
network is automatically built up to
perform QoS and QoE monitoring of
live streaming channels. Users can
observe how their content delivery
networks are performing and monitor
the performance of video encoders
across their entire distribution
system. " Telestream Cloud Stream
Monitor enables successfully delivered
channels in highly efficient and costeffective ways, " says Kenneth Haren,
Product Manager at Telestream.
" Without effective monitoring you
don't have a channel. Having good
visibility of the health of a channel
centres on the ability to monitor and
analyse video data. "
Telestream has introduced new
functions and software-based features
for its PRISM waveform monitor. This
can be optioned with the traditional
SDI tools required in operations,
compliance, quality control and
post production workflows up to 8K
resolution. The same product can
also perform IP-based waveform
monitoring at up to 4K resolution
on 25G Ethernet. Enhanced HDR

Telestream's PRISM SDI-IP

and WCG reports and tools are also
available. The user interface and
API are remotely accessible. PRISM
enables multi-user flexibility, where
the operators do not need to be at
the same physical location as the
device. Touchscreen and dual-screen
options are supported, enabling
the user to adapt to their preferred
working
environment.
Through
software options, the system can
easily be configured for production,
engineering, QC, IP signal sourcing and
IP measurement.
Triveni Digital's StreamScope XM
Verifier software receives, analyses
and records ATSC 3.0 broadcast
streams from RF, Ethernet, and PCAP
file inputs. As a Windows app or
cloud-based SaaS, Verifier displays
bitrates, signal tables, RF parameters,
packet errors, subframe and PLP data.
The operator can perform IP stream
validation, video and audio rendering,
file recording, and other test functions.
Venera's Pulsar QC system operates
at up to 6x faster than real-time
analysis speed for HD content and
near real-time analysis for JPEG2000 4K content. Testable video
parameters
include
blockiness,
brightness, cadence, chroma hits,
chroma line, clipping, coloured frames,
colour gamut, combing, credit roll,
dead pixels, field dominance, flash
frames, freeze frames, luma/chroma
levels, bar artifacts, framing issues
and photosensitive epilepsy. Testable
audio parameters include sampling
frequency, dropout, silence, loudness,
phase mismatch and language ID.
HDR, IMF and 4K are supported.
