N2 - This paper introduces the recent design and development of a converged IPTV service that has been deployed within a live test-bed (Living Lab) at Lancaster University for thousands of students. High quality audio-visual content is distributed over heterogeneous IP-based content networks, on both set-top box and web-based platforms. Peer-to-peer (P2P) technologies are exploited to provide energy efficient and low-cost delivery for commercial and user-generated content. The infrastructure and functional components are first presented exploring a number of key designs that facilitate the entire eco-system of content ingest, transcoding, P2P tracking, distribution, statistics, end systems, as well as integration of social networking. Due to the dynamic nature of P2P distribution, a quality measurement service with respect to user experience is also essential for the service evaluation and diagnosis. A multimodal QoE measurement framework which evaluates the IPTV services by collaborating measurements with a variety of different aspects is presented. Results of a use case are also described to verify the effectiveness of the measurement framework in exploiting relevant metrics from service components.
