and DVI-I rasterised outputs which
allow detailed video and audio
parameters to be checked on a
separate monitor in full 1920x1080
HD resolution. Measurements can be
displayed as waveform, vector, picture,
audio and SDI status. Display layout
is user customisable from a wide
range of available settings including
individual full screen or user-defined
combinations. These settings can be
configured from the front panel or
via a standard USB pointing device
and then saved for fast recall. 60
user-definable presets are accessible.
These can be labelled and displayed
on-screen. A reference marker can
be placed at any position on the
rasterised image.
Mediaproxy's LogServer platform
provides continuous multi-channel
recording, review and live monitoring
of video, audio and real-time data
sources from 4K/HD/SD IP and OTT
sources. Available applications include
transport stream analysers and IP
multi-viewers with data monitoring
options for transport stream events,
loudness, captions and DVB subtitles.
Mediaproxy's
LogPlayer
allows
metadata search, as-run and viewer
ratings integration, media export,

transcoding and content retrieval
across multiple distributed servers
recording H.264, HLS and native MPEG
formats in parallel.
Nevion's TNS4200 1U media
monitoring probe allows continuous
monitoring of IP/Ethernet and DVB-ASI
transport streams. It can be configured
via a web interface and interact with
overlaying network management
systems. The probe can accommodate
up to 300 simultaneous TSoIP inputs,
20 simultaneous ASI inputs or eight
simultaneous DVB-S/S2 /T/T2 inputs
Phabrix' Qx is designed for testing
UHDTV formats. It can generate and
analyse signals with up to 48 Gbit/s
payloads, offering both video and
audio support. A real time 12G-SDI
physical layer analysis (eye and
jitter) tool-set with automatic SMPTE
compliance measurements allows
testing for both UHDTV1 and UHDTV2.
The Qx is controlled using a mouse,
keyboard and 1920x1080 display.
Support for HDR , WCG, HFR and
object-based audio formats will be
provided as the standards develop. The
Qx hardware platform also supports
uncompressed SDI interfaces as well as
SMPTE ST 2022-6 over 10GbitE for IPbased infrastructures.
Promax' HD Ranger 3 analyser offers
HEVC signal demodulation compatible
with the H.265 HEVC DVB-T2 HD
format which can handle up to 1080p.
Hybrid operation allows the equipment
to be controlled via touch-panel
and conventional keyboard. It can
receive a T2-MI signal in the form of
both ASI or IP formats, performing
IP transport quality measurements,

Qligent has introduced new
visualisation tools for its Vision
cloud monitoring platform
that strengthen regulatory
compliance,
bandwidth
optimisation and workflow
management for broadcasters
and MVPDs. The new features
include an off-air counter
which monitors and records how long
a station has been off-air or out of
compliance due to signal loss or other
performance issues.
Rohde & Schwarz' DVMS product
range is designed for monitoring
digital TV networks. It includes the
DVMS1 and the DVMS4. Typical
applications are signal monitoring at
a transmitter site, satellite uplink or
network headend. Up to four signals
can be monitored simultaneously.
Sencore's AG 9000 provides HEVC
4K decoding for monitoring real-time
linear distribution video feeds. With up
to 18 channels of decoding in a 2U Ross
openGear 3.0 frame, it delivers either
a full resolution 2160p output via HDMI
or down-converted 1080p50/60 video
via 3G-SDI. The AG 9000 decodes
video services up to 80 Mbits/s.
Tektronix' Prism can monitor a
variety of IP statistics including video
quality and diagnostic information,
enabling an operator to check QoS
levels involving compressed or
uncompressed video transmission
through SDI/IP signal paths. It is
intended for monitoring SDI/IP hybrid
environments including master control
rooms, production studios, OB vans,
and signal contribution/distribution
centres.
Triveni Digital's StreamScope EM50 provides continuous, real-time
quality of service updates on hosts,
ports, transport streams, and services
across any DTV network, from 8VSB
to 10GigE. With the overview screen,
operators get a quick, high-level look
at service presence and QoS for the
entire monitoring network. A video-

wall screen view provides live video
thumbnails as well as QoS numbers
for all the services being monitored.
Operators can then choose to create
a report or click on the thumbnails to
identify the problem.
Vidcheck's
Vidchecker
and
Vidchecker-Post have become the
defacto file-based automated quality
control solution for MXF-based AS11 UK DPP content. Vidchecker has
recently been expanded with the
addition of new features for checking
Interoperable Master Format (IMF)
as well as other 'flavours' of AS11. Vidcheck has also announced
Vidchecker V.7 with automatic video
segment
detection,
multi-lingual
alerts and peak attenuation correction
as well as many more automated
correction options. Vidchecker V.7
works faster than any previous version,
taking advantage of the parallel
processing architecture employed
in modern digital microprocessors.
Most of the V.7 features are also
available on Vidchecker-post. The key
difference is that Vidchecker is the
faster of the two applications, capable
of testing and correcting multiple files
simultaneously.
Video Clarity's RTM is an automated
quality-of-experience monitor which
measures the quality between two
locations. It does this after the set-top
decoder has had a chance to conceal
or repair the problems. RTM measures
the video quality, audio quality, audio
or video delay (offset), audio program
loudness and VANC data accuracy.
If any of these drop below a preset
threshold, then an alarm is triggered
and the sequences are saved.
