Video Quality Analysis Software
VQS1000 Data Sheet
Triggered-capture of streams and logging of live data enable offline
analysis of service quality issues
Features & Benefits
Reliable and sophisticated analysis algorithms applied to decoded
MPEG-2 or H.264 video to identify stuck, black, macro-blocking, and
sion artifacts. This enables operators to distinguish between
compres
impairments resulting from network distribution versus artifacts resulting
from compression
Industry-first uniqu e visualization tool with innova tive impairment
s highlights the location and severity of video defects, enabling
display
engineers to clea rly see and validate the presence of imp airments on
the image
Analysis of decoded MPEG-2, AC-3, MPEG-2 AAC, and MPEG-4
AAC aud
BS.1770/1771
Trending of video and audio metrics to help diagnose intermittent and
time related problems
io to identify loudness problems in accordance with ITU-R
Logging of live data to capture min, max, and ave
and bit rates at user-definable time intervals enables long-term quality of
experience for a s ervice to be assessed and optimized
Connect either directly to an Ethernet switch or integrate with Tektronix
IP Video and DTV Monitoring probes
IGMP support for analyzing multicast streams beyond the local ro uter
Integrate with Tektronix IP Video and DTV Monitoring probes so that
QoE errors appear in the monitoring probe log interleaved with the TS
and physical layer (IP and RF) QoS errors. This enables users to easily
distinguish between errors that are caused by network issues (dropped
packets, CC errors, etc.) and errors which do not have a corresponding
network issue and are therefore caused by an upstream encoder
problem
rage impairment values
Applications
Affordable QoE Monitoring – Alarms with configurable impairment
magnitude, duration, and frequency thresholds can be generated to
alert users to content that will impact customers’ viewing and listening
experience
Network Performance Optimization – QoE and bit rate monitoring and
logging enable in-service tuning of networks to deliver the best viewing
experience possible within band width constraints to viewers
Remote In-service Diagnostics of Broadcast Delivery Issues – Combined
with physical transport alarms from the Tektronix IPM400A or any
MTM400A Series probe, operators can determine if the source of a
problem is in the content (for example, over-compression) or in network
distribution layers
