ClassX for Developers

What's here

The ClassX software consists of the following modules:

• A transcoding module that converts camera-captured videos into a format that facilitates video streaming with interactive selection of region-of-interests (RoI).

• A server module that implements the protocol for streaming video with interactive selection of region-of-interests.

• A client player that implements the protocol for streaming video with interactive selection of region-of-interests. In addition, the client player also implements a user interface for pan/tilt/zoom control and spatial random access.

• A RoI automatic selection module that produces recommended views mimicking human camera operation.

• A slide synchronization module that performs automatic matching between lecture videos and electronic slides.

• A mobile client module that supports interactive region-of-interest video streaming and playback on mobile devices. Users can pan/tilt/zoom on a video using natural hand gesture. The current version only supports Apple iOS.
