Tektronix Shows Off Sentry's Advanced Capabilities at The Cable Show
BEAVERTON, OR, Jun 13, 2011 (MARKETWIRE via COMTEX) --
Tektronix, the leading provider of digital content monitoring
solutions, will demonstrate the advanced capabilities of its
award-winning Sentry(R) digital content monitor in the CableNET
Pavilion of The Cable Show, June 14-16 in Chicago. This year's
demonstrations will include Sentry's unique Perceptual Video Quality
(PVQ) scoring system and Sentry's ability to monitor enhanced
television (ETV) and advanced advertising applications based on the
increasingly popular Enhanced TV Binary Interchange Format (EBIF).
Sentry's groundbreaking PVQ scoring system enables MSOs to accurately
gauge the severity of video errors that are caused by over
compression, which are difficult for other monitoring systems to
detect because the transport streams often appear error free. Sentry
can identify these errors due to its unparalleled ability to monitor
the sequence layer, the GOP layer, the picture layer, the slice
layer, the macroblock layer and the block layer. When detected, PVQ
ranks errors similarly to the commonly used Mean Opinion Score (MOS)
system, so that headend technicians can easily understand the
significance of the errors and take appropriate action based on the
severity of the problem.
Sentry's PVQ is the industry's only 'non-reference' perceptual
quality score that is fully calibrated against the Tektronix PQA 600
-- the industry standard for picture quality test and measurement,
used by leading encoder manufacturers worldwide.
Tektronix will also demonstrate how cable operators can monitor their
EBIF-based ETV and advanced advertising applications with Sentry.
Cable operators and programmers are increasingly looking to these
EBIF-enabled applications to generate new revenues and to enhance
viewer interactivity with the content. This drives the need for
comprehensive monitoring to ensure that these applications are being
For EBIF-based applications to work properly, triggers must be
embedded into program streams and when these triggers are activated
(by viewers), the additional data must be delivered to set-top boxes.
Determining if all these steps are performed correctly across an
entire channel line-up is not possible by simply measuring packet
loss alone or using other first generation approaches for ensuring
quality of experience (QoE).
Sentry's advanced detection capabilities, coupled with its constant
24x7 operation and scalability to simultaneously monitor hundreds of
programs, ads and EBIF-widgets make it the ideal solution for the
performance monitoring of EBIF-based applications.
"Delivering the best possible viewing experience remains a priority
for operators as they face ever more competition from telco,
satellite and increasingly over-the-top providers even as they
simultaneously strive to offer more compelling services and to
generate new ad revenues," said Eric Conley, vice president, Video
Network Monitoring, Tektronix. "We understand these complex needs and
continue add new features and functionality to Sentry to ensure it
meets their critical needs both today and tomorrow, whether it's
EBIF, Tru2Way, 3D or adaptive streaming."
Sentry is an award-winning, comprehensive content monitoring solution
for cable, telecom, IPTV and other video service providers. Sentry
enables the early detection, diagnosis and repair of video and audio
errors (i.e., video freeze, macro-blocking, loss of audio, etc.)
whenever or wherever they occur in the network, so service providers
can deliver services with excellent quality, thus ensuring an optimal
QoE for subscribers. Sentry accomplishes this insight through its
unique combination of an unprecedented visibility into network
anomalies at the IP and MPEG layers, scalability to monitor every
program in the network, and its real-time, 24/7 operation.
