Triveni Digital At CCW 2014
A

t CCW 2014, Triveni Digital
will demonstrate its metadata
generation and transport stream
analysis platforms, which are
designed to bring increased
operational efficiencies and cost
savings to broadcasters while
enabling them to provide a superior
quality of service (QoS) to viewers.
Triveni Digital will demonstrate
its award-winning StreamScope
MT-50 HDT, an optimised version
of its real-time DTV transport
stream analysis and troubleshooting
tool. Designed to bring increased
efficiency, ease of use, and quality
control to broadcast operators, the
StreamScope MT-50 HDT features

Triveni Digital's
award-winning
StreamScope MT-50 HDT

the most comprehensive MPEG
analysis engine available, a 10GigE
interface option, and a 16:9 HD
touch screen that can be swiped
by finger or a touch pen.
Through the intuitive, browserbased user interface, the system
displays video and audio thumbnails,
QoS and bitrate graphs, crosstab
analysis, and more, all in crystalclear HD quality, making it an ideal
tool for broadcasters looking to
monitor and analyse multiple DTV
transport streams and comply with
worldwide standards to ensure a
superior QoS. To detect inconsistent
audio levels, the StreamScope MT50 HDT features sophisticated
CALM analysis with triggered
recording functionality, enabling
broadcasters to deliver a better
audio experience to viewers that
complies with FCC regulations.
Triveni Digital's StreamScope
Portal will also be on display.
The award-winning portable,
tablet-based MPEG analysis
and monitoring tool offers
an ultra-personalised
form factor and a
variety of donglebased input
options that
help engineers
cost-effectively

perform real-time and file-based
MPEG-2/MPEG-4 analysis
and troubleshooting of
DTV transport streams
on ASI, RF, and
Gigabit Ether net
interfaces. Using
the StreamScope
Portal in combination
with other Triveni Digital
products, including StreamScope
MT-50, operators can maximise
operational efficiencies and cost
savings while ensuring superior
audio and video signals.
Triveni Digital will also showcase
GuideBuilder 5, the latest generation
of its metadata generation platform.
Utilising the comprehensive
electronic program guide (EPG)
generator, broadcasters can
generate timely and accurate
programming guides.
T h ro u g h G u i d e B u i l d e r 5 ,
broadcasters can automatically
ingest schedule updates from
multiple listing services; generate
standards-compliant PSIP and
DVB-SI metadata; and seamlessly
apply them to thousands of ATSC
and DVB channels and services. By
providing broadcasters with a single,
integrated metadata management
solution that supports PSIP and
DVB-SI, GuideBuilder 5 dramatically

Triveni Digital StreamScope Portal
a tablet-based MPEG analysis and
monitoring tool

speeds up their workflows, enabling
them to handle more services
at lower costs.
Available in a variety of
configurations, including integrated
servers, software for use on
customer-supplied servers, Virtual
Machine compatible software, and
as a cloud-based managed service,
GuideBuilder 5 provides flexible
support for any DTV provider's
deployment approach.
The enhanced GuideBuilder
platform includes updated user
interfaces, a modernised Linuxbased operating system, and is the
core system for the GuideBuilder
DM extension - the basis for ATSC
2.0 and ATSC 3.0 deployments.

A New Way To Measure Video Quality In The IP Domain
By Adam Schadle
Vice President Video Clarity

C

ontent distributors must
continually test new codec
technologies to ensure that
distribution setups are primed to
deliver the best possible video
quality at multiple bit rates, frame
rates, and resolutions.
Reference-based video quality
testing, whereby the quality of the
output is measured against the
source content, is the most accurate
way to do it. But for IP and Internetbased delivery methods, that testing
can be a challenge because you
must first scale the source to
lower-than-broadcast resolutions
to match the downstream video
- and that scaling phase is often
where artefacts arise that taint the
rest of the test.
When testing IP streams, the best
way to arrive at a pristine reference
is to use the same encoder to create
the reference as you do to create
the downstream deliverables. A

new methodology for measuring
video quality in the IP domain
does just that.
When you reduce the resolution
using the target processing device
to match the test profile's resolution
at the highest possible bit rate, you
minimise the differences in artefacts
and degradations that result. After
creating the references and test
streams in this way, and then using
the same human-perception-based
measurement system and scoring
index throughout the testing process,
a video engineer with a trained eye
can visually compare the reference
and the processed streams side
by side while considering the
resulting score.
The process is repeated for each
stream that needs testing, creating
a new version of the reference for
each profile or device under test, and
making incremental adjustments to
the variables one at a time in order

to test the effect on quality.
