Traditionally, quality of service (QoS) metrics
such as packet loss, delay, and jitter have been
used to measure the application performance on
an end device. However, with increased diversity
in application requirements of multimedia services
and different content types, users’ quality
of experience (QoE) instead of networks’ QoS is
becoming an increasingly popular term in the
mobile video sector. QoE metrics tend to measure
user perception of delivered multimedia
services instead of counting on network service
parameters. Many tools have evolved for evaluating
video quality delivered to the end user
using subjective or objective methods.
