Monitoring Quality of IPTV Services

Monitoring Quality of IPTV Services

Internet Protocol television (IPTV) services have become a major source of revenue for carriers. Accordingly, monitoring quality of video and audio services is becoming increasingly important. Packet loss, out-of-order packet rate, and jitter are three key factors that affect quality of video and audio services. Artifacts or pixelation may occur on a terminal even if the packet loss rate or out-of-order packet rate is less than 1/10000, and a small amount of jitter may cause a black screen. These problems will seriously affect the revenue and reputation of carriers.

On the IPTV network shown in Figure 16-6, if the service quality deteriorates, you can deploy eMDI on the access switch, aggregation switch, or core switch through the NMS. eMDI can then monitor service flows, collect monitoring indicator statistics, and demarcate faults.
