Shapes Continued Innovation Across All Triple-Play Services
Chelmsford, MA -- Brix Networks, the trusted provider of the most
widely deployed service assurance solutions for interactive
applications, today announced an enhanced IP video quality algorithm
-- the Brix Video Quality Index (Brix VQI) -- that ensures providers'
success with their IPTV rollouts.
"In order to effectively deliver profitable triple-play services,
cultivate customer loyalty, and grow market share, it is essential
that network operators provide their subscribers with high-quality
offerings," said Robert Travis, director of product marketing, Brix
Networks. "Our VQI technology is a critical component of our
comprehensive service assurance platform, and helps determine the
overall quality of a variety of existing and emerging IP-based video
applications, such as IPTV, video-on-demand, and interactive video." |

According to a recent Light Reading Insider's report, "IPTV: Where the
Money Is," IPTV will capture 65 million subscribers worldwide by 2010,
and carriers will spend an estimated $21 billion over the next five
years in order to deploy the systems needed to deliver those services.
The Brix VQI is an objective measurement scale for video over IP
networks and applications providing accurate, easy-to-understand
metrics for highly distributed, large-scale carrier and enterprise
networks. The Brix VQI incorporates the impact of network transmission
quality -- the most important factor contributing to video quality --
and quantifies the effect latency, packet loss, jitter, packet
discards, buffering, and re-buffering events have on a video service.
With today's announcement, the Brix VQI has been enhanced to be
"application aware," meaning it can distinguish, analyze, and
correlate the key performance indicators (KPIs) related to data
impairments that, in turn, contribute to picture jerkiness,
blurriness, or no picture in video-based services.
"Brix Networks has established itself as a leader in the VoIP testing
and monitoring market," observed Jessy Cavazos, program manager,
communications test and measurement practice, at Frost & Sullivan.
"Due to its broad customer base and extensible product family, it
doesn't surprise us that the company is also taking a leadership role
in the IP video service assurance market."
"Developed with ongoing standards initiatives in mind, Brix VQI is an
innovative video quality algorithm that yields useable metrics to
generate an IP video quality score -- per video stream -- that
accurately represents the user's quality of experience," said Brix
Networks' chief technology officer, Kaynam Hedayat. "VQI builds on our
extensive industry-leading experience in VoIP networks, and quantifies
the impact that latency, initial wait time, network jitter, packet
loss, and other application-level impairments have on the overall
performance of an IP video service."
Similar to the widely accepted Mean Opinion Score (MOS) that has
historically been used to determine voice quality, the Brix VQI
measures video quality on a scale of 1-5, with higher scores
reflecting fewer impairments and a greater likelihood of overall
customer satisfaction. The codec-independent Brix VQI is a valuable
tool for providers to monitor and predict the expected quality versus
actual quality of their IP video services.
The patent-pending Brix VQI technology goes beyond providing typical
media measurements and, by leveraging the unique Brix Tri-Q Analysis
capabilities, also analyzes and monitors the session quality,
signaling quality, and delivery quality of IP video services.
The Brix VQI is used for continuous monitoring and to baseline
performance, and also helps increase service visibility from the edge
of the IP network to the core of IP video delivery.
Brix Networks' seamlessly integrated hardware and software products,
collectively called the Brix System, are strategic and indispensable
service assurance solutions that proactively monitor VoIP and IP video
quality. Network operators use the Brix System to guarantee the
successful launch and ongoing, profitable operation of their VoIP and
IP video services.
The company also offers two free, self-service testing portals -- www.TestYourIPVideo.com and www.TestYourVoIP.com -- that enable users
to independently measure the quality they are receiving from their
interactive or streaming IP-based video services and VoIP connections,
respectively.
