Small screen sizes, limited bandwidth, and low computational power often prohibit streaming of high-resolution videos to mobile devices over a wireless network. Recent advances in interactive region-of-interest (IRoI) video streaming technology enable users to interactively control pan/tilt/ zoom, while provide bit-rate and complexity savings. One recent application of IRoI video streaming is ClassX developed at Stanford University. It offers an open-source experimental platform for interactive online lecture streaming. In this technical demonstration, we present ClassX Mobile, which extends the current ClassX system and delivers high-quality interactive video to smartphones and tablets with multi-touch screens.
