Spectra2|VQM Portable Monitoring and Diagnostics Package Eases
Video over IP Development, Deployment, and Operation
Beaverton, OR -- Tektronix, Inc. (NYSE: TEK - News), a worldwide
provider of communications network management and diagnostics,
announced the availability of the Spectra2|VQM (Video Quality
Measurement) monitoring solution for the diagnosis and analysis of
streaming video transmitted over Internet Protocol (IP).
Spectra2|VQM helps users identify the causes of poor digital image
quality, such as packet loss, delay or data corruption in the IP
transport network. Spectra2|VQM is the first portable monitoring
solution with support for multiple-level Quality of Service (QoS)
scores and video industry standard, non-proprietary Forward Error
Correction (FEC) analysis that carriers and cable networks can use
in the emerging video over IP opportunity.
The Spectra2|VQM is a Windows-based software package that is part of
the Tektronix Internet Protocol Diagnostics (IPD) product portfolio.
The IPD portfolio provides network equipment manufacturers and
service providers with easy-to-use test and measurement tools for
the analysis and QoS measurement of media over IP and protocols in
the core of converged multi-service networks. |

Spectra2|VQM monitors video streams transported over RTP and
MPEG2-TS (transport stream) protocols. Spectra2|VQM supports
measurement of multiple concurrent standard-definition (SD) video
streams as well as high-definition (HD) video streams. Users can
generate real-time video streaming quality metrics such as presence,
accuracy and objective Mean Opinion Scores (MOS) that they can use
to diagnose a range of video-related problems at the IP, transport,
and content levels. The availability of MOS QoS measurements based
on transport and actual uncompressed video content allows users to
correlate QoS at both the transport and content levels.
"Equipment manufacturers and service providers want to ensure the
highest quality digital video transmission for their customers,"
said Richard Kenedi, Senior Director, Diagnostics, Communications
Business, Tektronix. "They know that the provider who most
consistently meets customer quality standards will inevitably win
the most loyal customers in the new market for IPTV content.
Spectra2|VQM has all the advantages of Spectra2 including ease of
use as well as Tektronix' expertise in the IP testing space. Network
operators can verify that subscribers are receiving what they
request, when they requested it and at acceptable quality, by
continuously monitoring video transport and content on
user-selectable channels."
Spectra2|VQM supports both CoP-R3 and RFC 2733, the two main non-
proprietary, video industry FEC analysis standards. Spectra2|VQM can
perform and analyze FEC algorithms, a technique for improving the
reliability of packet transmission over networks which do not
provide guaranteed packet delivery. This technique allows the user
to view the effectiveness of the correction mechanism and ensure a
successful user experience. The software can detect codec
over-compression and incorrectly configured FEC for fine- tuning
bandwidth versus quality. Users can detect perceived video image
quality in real time or historically for individual video streams so
that they can develop systems and services that match the visual
quality that viewers have come to expect from traditional television
broadcasts.
"Tektronix is excited to make available today what we believe is the
best portable monitoring solution that carriers and cable networks
can use in the emerging video programming over IP opportunity," said
Kevin Keough, Senior Director of Strategic Initiatives,
Communications Business, Tektronix. "Long term, Tektronix'
unquestioned market leadership in Video test solutions combined with
our IP and telephony experience offers unique value to our customers
in these times of convergence and complexity."
At the core of the Spectra2|VQM video monitoring solution is the
ability to detect specific problems. Correlation between the MOS and
other factors that include Packet Loss, Delay and Jitter along with
MPEG2-TS priority statistics, gives a technician the tools necessary
to determine the problem. Integrated reporting analysis tools
provide interactive views of all Spectra2|VQM video metrics. Video
data capture and decode also ease trouble- shooting activity.
Spectra2|VQM allows a technician to view the actual video in
progress for a visual indicator of quality. Spectra2|VQM can also
track metrics graphically in real time. Users can export statistics
to a file or use the integrated online analysis tools to browse
historical data.
