Ensure IPTV Quality of Experience
Quality of Experience (QoE) describes how well a service satisfies user expectations. It is a rating of service performance from the user perspective. For IPTV, CSPs are expected to achieve equal or better QoE than traditional cable and satellite TV providers. Unfortunately, early implementations of IPTV are proving that this is quite a challenge.
Before service deployment, CSPs and NEMs evaluate equipment and systems in their lab by quantifying performance. Since IPTV QoE assessment is subjective, CSPs and NEMs need to understand all the factors of IPTV QoE and how to translate these subjective QoE factors into objective metrics that can be quantified using a proper test methodology. Comprehensive knowledge of individual devices as well as end-to-end network systems is also required.
