IPTV systems have seen widespread deployment, but often lack robust
mechanisms for monitoring the quality of experience. This makes it
difficult for network operators to ensure that their services match the
quality of traditional broadcast TV systems, leading to consumer
dissatisfaction. We present a case study of virtual RTCP, a new
framework for reception quality monitoring and reporting for
UDP-encapsulated MPEG video delivered over IP multicast. We show that
this allows incremental deployment of reporting infrastructure, coupled
with effective retransmission-based packet loss repair.
