Social and interactive TV has been held back by both technical and ecosystem limitations over the past two decades. Technical approaches to enabling Social TV have relied on proprietary TV middleware, whose success in turn depends on widespread and expensive technology upgrades by cable and satellite TV operators. Additionally, users have increasingly adopted to socialize on the web, even where it pertains to TV [2]. This makes any attempts at creating TV specific social communities unattractive to users, who already have a social presence (and identity) on the web. This paper proposes an alternate outside-inoverlay architecture for Social TV. Such an architecture leverages the emergence of a second screen with strong and built-in interactivity, and an approach to reuse rather than replace web social software to enable Social TV. In this paper, we briefly describe the motivations, architectural elements and implementation experience around such a system.
