Flash Media IP-Based Video Switcher

The Flash Media IP-Based Video Switcher is an open-source prototype virtual studio, allowing real time production and switching of IP-based audio and video sources from around the world. The system architecture utilizes Flash Media Enterprise Server, allowing a studio client to connect to multiple camera clients and communicate to operators via audio and text intercom. Standard switcher functions including preview and synchronization are provided, and the live show can be unicast or multicast to viewer clients.

The Virtual Studio

The virtual studio is designed to act as a test bed for research and development that lowers the barriers of developing real-time multicast applications, such as making adaptive bitrate multi-platform streaming simpler, creating re-usable components to extend social interactions, and moving video production out of the studio and into the ether.

The Virtual Studio and Multicast System is based on another open-source project: the Real-Time Component Framework (RTCF) for Flash Media Server. The system makes extensive use of Adobe software including:

The Virtual Studio and Multicast System is under development at Ryerson University in Canada and the Media University (Hochschule der Medien) in Germany. We are particularly interested in research and development that lowers the barriers to developing real-time multicast and peer-to-peer applications such as adjusting for latency effects in the virtual studio, optimizing fail-over scenarios like IP-based multicasting to P2P multicast and then to TCP based unicast, making adaptive bitrate multi-platform streaming simpler, creating re-usable components to extend social interactions, and moving video production out of the physical studio as much as possible.

The system supports role-based access controls and provides an administrative interface to manage users, studios, and roles.
