   Validating IPTV Service Quality Under Triple Play Network Conditions
With so much at stake, it is not surprising that ‘IPTV QoE’ (IPTV Quality of Experience) has become one of the most popular buzz words within industry publications, tradeshows, and forums. IPTV QoE refers to how well the video service satisfies user’s expectations. The IPTV quality experienced by subscribers must be equal to or better than today’s cable and satellite TV services, or else service providers run the risk of significant subscriber churn.

IPTV QoE: Understanding and interpreting MDI values
  The video component of the triple play offering presents unique demands on the network because of its high bandwidth requirements and low tolerance to jitter and packet loss. The media delivery index (MDI) measurement gives an indication of expected video quality – ultimately, users’ QoE – based on network level measurements. It is independent of the video encoding scheme and is a lightweight, scalable alternative to measurements such as MPQM and V-Factor that decode and examine the video itself.
