Video Clarity Demonstrates
IP Networks

Video Clarity has demonstrated a test system for
IP Networks with PacketStorm Communications
and Macnica Technology...

V

ideo Clarity and PacketStorm
Communications demonstrated
how manufacturers and programme
service providers can apply a
comprehensive test system for the
new SMPTE suite of standards for
Professional Media over IP Networks
(SMPTE ST 2110). The ST 2110 suite of
standards (-10, -20, -21, -30, and -40) is
currently in the final draft stage.
This demonstration which took
place recently at IBC featured a fully
operational interactive demonstration
of IP network transport, IP network
emulation, media flow analysis,
quality and performance testing for
uncompressed video, audio, and
ancillary data.
IP Transport
In the demonstration, IP transport
technology was courtesy of Macnica
Technology, whose transmit and
receive solutions augment or replace
today's SDI-based architectures for
delivering multiple types of highquality, contribution-level content.
PacketStorm
Communications
provided the IP network emulation to
simulate actual network and media
over IP analysis conditions to measure
flow characteristics to ST 2110 based
on ST 2110-21. Video Clarity's RTM
real-time monitor will provide the
source video playout and test the
source against the network output.
The RTM system plays uncompressed
content while it continuously measures
audio/video quality, as well as lip sync

and loudness, and applies a user-set
threshold for error events that are
captured automatically for playback
in a side-by-side comparison of the
source and downstream programme
signal.
Uncompressed IP Player
Video Clarity demonstrated the
ClearView IP video analyser. Designed
for broadcast-product manufacturers
and programmers to use in their test
labs, ClearView IP plays or records
up to two channels of uncompressed
video from a high-capacity testing
server into a SMPTE-compliant
network. ClearView IP can apply new
IP standards and play while recording
in the IP domain - critically important
features for being able to test video
quality in a new IP world.
Also on display was ClearView
Player IP, a high-capacity server
specifically designed for use in an
IP infrastructure, with record and
playback functions for uncompressed
video using new IP-related video
transport
standards.
ClearView
Player IP can record one channel
and play back up to two channels of
uncompressed video programming
into a SMPTE-compliant network.
Manufacturers and programmers
rely on it to subjectively view video
for quality or to feed the output to a
processing engine for product testing
and encoder prequalification. It can
also be deployed for broadcast or
venue-based playback.

Video Clarity also demonstrated its
ClearView 4K Analyzer, which provides
various functions for importing and
analysing HDR video with support for a
wide colour gamut. Whether imagery is
created with colour space for PQ 2020,
HLG, or ICtCp, ClearView 4K systems
can apply the correct importing
function for these new video colour
spaces.
SaaS ClearView & RTM Solutions
On show were two new SaaS
offerings for broadcasters and content
owners that deliver video through
the Amazon Web Services (AWS) EC2
platform. Video Clarity's ClearView
video quality analyser and RTM realtime monitor are now available as an
addition to AWS EC2 cloud subscription
services, giving subscribers in
broadcast, IPTV, and any other
content-delivery scenarios licensable
SaaS versions of the video quality
measurement tools. With a license,
AWS EC2 subscribers can use either
the ClearView application or the RTM
application for full-reference-based
A/V quality testing in the AWS cloud,
just as they would in a hardware-based
operation.
ClearView Venue Player
Making its European debut at the
show was the ClearView Venue Player,
a video server that automatically plays

IP Network Testing demonstration

multiple uncompressed segments of
content to multiple screens in precise
timing and sequence. ClearView Venue
Player is designed for broadcast
facilities, theme parks, live events,
staged shows, and other environments
that rely on repeated, synchronized
video playback for entertainment and
display. The ClearView Venue Player
offers up to eight terabytes of storage
and up to eight 2K outputs or two 4K
outputs in a 1RU size.
The included Venue Player software
is what makes synchronized playback
possible because it can automatically
and interactively select sequences for
playback in multiple video formats on
up to eight screens at once.
New control functionality courtesy
of Venue Player Manager enables
browser-based
control
over
configuration and playback. All Venue
Players now provide a web server for
browser-based control on a networked
computer or tablet. Venue Player users
can set up, jog, shuttle, play, rewind,
and queue the output of each system
from anywhere with an internet or
internal facility network connection
to one or multiple Venue Players.
Browser-based control gives users in
both venues and broadcast test labs
an easier way to manage playback on
multiple screens.
