VQmon/HD’s quality analysis algorithm considers these temporal phenomena in order to
calculate perceptual quality scores that correlate as accurately as possible to scores obtained
from subjective tests of live viewers.
A.2 VQmon/HD Quality Analysis Algorithm *
This section describes VQmon/HD’s video and audio quality analysis algorithms and lists some
of the key metrics reported by VQmon/HD as part of the Telchemy Video Quality Metrics
(TVQM) data set.
A.2.1 Video Stream Analysis
VQmon/HD’s video quality analysis algorithm analyzes RTP or MPEG-2 Transport video
streams and generates real-time perceptual quality scores and other diagnostic metrics.
Video codecs supported by VQmon/HD include:
• Motion JPEG
• MPEG-1
• MPEG-2
• H.261
• H.263/263+
• H.264
• MPEG-4
• VC-1
Figure 2-7 depicts the various components of the VQmon/HD video quality analysis algorithm
and the metrics produced by each component.
