  Coupled schemes between service-oriented architecture (SOA) and Web 2.0 have
recently been researched. Web-based content providers and telecommunications
company (Telecom) based Internet protocol television (IPTV) providers have
struggled against each other to accommodate more three-screen service
subscribers. Since the advent of Web 2.0, more abundant reproduced content can
be circulated. However, because according to increasing device's resolution and
content formats IPTV providers transcode content in advance, network bandwidth,
storage and operation costs for content management systems (CMSs) are wasted.
In this paper, we present a user centric CMS for open IPTV, which integrates
SOA and Web 2.0. Considering content popularity based on a Zipf-like
distribution to solve these problems, we analyze the performance between the
user centric CMS and the conventional Web syndication system for normalized
costs. Based on the user centric CMS, we implement a social Web TV with
device-aware function, which can aggregate, transcode, and deploy content over
social networking service (SNS) independently.
