There are new types of tests needed to verify that
IPTV systems are working correctly. Not knowing what these tests are can
result in unhappy customers, getting fired, or even more terrible things
could physically happen to technicians if the IPTV system fails in the
middle of a major sports event such as the Superbowl or World Cup (furious
fans). The good news is that there are just a few key types of tests that
you need to understand to keep your IPTV systems working well.
Just when you thought learning new types of testing
for digital TV systems was over, deploying IPTV systems uses new packet
data transmission which can have different types of distortions and
testing challenges. Testing for packet loss is not enough to ensure block
errors, frozen frame, or even loss of signal does not occur. Testing for
quality of service (QoS) has changed to quality of experience (QoE).
Services are provided in multiple layers which can interact and mislead
testing and diagnostic equipment.
If you are involved or getting involved in testing
IPTV systems, this paper can be a good introduction to the new types of
tests you will need to perform.
