Instant Broadcasting System: Mobile Collaborative Live Video Mixing

With Instant Broadcasting System, people can collaboratively produce, edit, and broadcast live video using only mobile phones, a laptop computer and available mobile networks. In this demonstration, it is used as a VJ system that supports visitor-generated video, flexible content selection, a communication back channel, and real-time loop editing. These features move the system beyond previous webcam-based VJ concepts.  

The first generation of applications in this genre enables broadcast of live video streams from various user contexts over mobile networks such as 3G. Instant Broadcasting System explores a second generation of such applications, in which professional techniques for col-laborative live video editing are made available on mobile platforms. Using networked camera phones, it is possible to mix live concurrent video streams from multiple users for public display on the internet and locally. The design space adapts these new possibilities, previously only available to professional TV-production teams, to amateurs in various contexts.  For example, parents might use it to broadcast multiple live images of soccer matches where their children are competing.  Or, as demonstrated by the Instant Broadcasting System, night-club patrons and viewers of public exhibitions can share their experiences in real time.
