Not All Packets Are Equal, Part I: Streaming Video Coding and SLA Requirements
January/February 2009 (vol. 13 no. 1)
pp. 70-75
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.
