TV6: A Revisit to System Design, User Socialization and Content Recommendation in Social TV

The move to social TV has challenged the traditional TV experience by allowing users to interact with their friends and receive social multimedia contents when they are watching videos. Social TV has made the social experience equally important to users as the video contents. The rapid emergence of online social network service and video sharing service in today’s Internet, as well as the open interfaces (e.g., Open API) make it possible for a third party to build a social TV system, based on existing social network and online video service infrastructures. In this paper, we share our experience of designing, developing, deploying and operating TV6—a social TV system that embeds multiple online social network systems and online video sharing systems. Through detailed analysis of TV6, we present our observations and insights on provisioning superb social TV experience to users, including social content provision and traditional video content provision.
