ABSTRACT
In this first part of a two-part article, the authors consider the network factors that impact the viewers' quality of experience (QoE) for IP-based video-streaming services such as IPTV. They describe the IP service-level requirements for a transported video service and explain MPEG encoding to help readers better understand the impact that packet loss has on viewers' QoE.
INDEX TERMS
IP, video, SLAs, QOE, MPEG, video packet loss, packets & protocols
