IPTV Ops use Witbe to Monitor Mediaroom
Witbe is showcasing its quality of experience (QoE) solutions at the IPTV World Forum 2010 in London from March 23-25.
Witbe solutions are used by tier 1 operators world-wide including many using Microsoft Mediaroom in Europe, Asia, and the Middle East. The list includes Deutsche Telekom, SingTel, Portugal Telecom, Vodafone Portugal, T-Com Slovakia and Du.
The Mediaroom platform offers subscribers a wide variety of content delivery applications such as video on demand (VOD) and digital video recorder (DVR). Witbe solutions help Mediaroom customers measure the added value of such features and ensure subscriber satisfaction by providing key performance indicators such as:
-
Channel changing times: ICC typically offers the fastest channel changing times in IPTV, around 600 ms.
-
Menu response times for the User Interface (UI) of any interactive service.
- Performance and availability of VOD and DVR assets.
- Video and audio quality using a Mean Opinion Score (MOS) based on an analysis of the actual video and audio signals coming out of the set top box.
Witbe's approach to QoE monitoring is designed to simulate as closely as possible the subscriber experience by using active robots rather than passive probes.
Robots are connected to the video and audio signals behind the set-top box enabling them to "see" and "hear" just like a subscriber. They interact with the service by sending infrared signals to the set-top box much like a remote control. They are therefore capable of providing accurate application response times as well as metrics on video and audio quality.
