Abstract
Multimedia streaming is becoming an integral part of people's life. In this talk, I will present data analysis on
user's viewing behaviors based on two streaming services: YouTube and IPTV. YouTube is the largest VoD service for user
generated contents (UGC). Nowadays, UGC sites are creating new viewing patterns and social interactions, empowering
users to be more creative, and developing new business opportunities. In this talk, I will present the intrinsic
statistical properties of video popularity based on real traces from YouTube. Understanding the popularity
characteristics is important because it can bring forward the latent demand created by bottlenecks in the system (e.g.
poor search and recommendation engines, lack of metadata, etc).
Another popular form of streaming is IPTV. After many years of academic and industry work, we are finally witnessing a
thriving of IP multicast in large scale deployment of IPTV services. In the second part of this talk, I will present
for the first time previously hidden TV viewing habits based on real traces. I will also discuss the feasibility of
using peer-to-peer distribution for scalable IPTV system and supporting advanced viewing controls such as DVD-like
functionalities, content recommendations, and target advertisements.
