MediaNet: A High Performance Platform for Network Media Processing

• U-Net: User level network architecture. User level access to the network dramatically improves performance and facilitates the development of new communication protocols The order-of-magnitude improvement in LAN communication makes parallel computations on workstation clusters practical.
  
• CMT: Toolkit approach for reliable distributed audio/video applications. CMT is a portable toolkit for building applications that include audio and video, facilitating the rapid prototyping of multimedia applications.
• CM-Horus: Group communication primitives for multimedia. We are adapting an industrial strength group communication tool, Horus, to multimedia applications. Such secure and reliable group communication primitives are critical for advanced military and commercial multimedia applications
  
• Tcl-DP
  A distributed programming extension to Tcl/Tk. Adds TCP and IP connection management, RPC and distributed object support to Tcl/Tk.
• Rivl
  An extension to Tcl/Tk that treats images, video and audio as first class data types.
• Dali
  A high performance follow-on to Rivl, Dali provides primitives that allow programmers to easily create high-performance video processing programs.
• Compressed Domain Transcoder
  Research into real-time MPEG to JPEG transcoding. A compressed-domain transcoder is publicly available.
• Lecture Browser
  This is a system to digitize and store lectures given in Philips 101. The lecture videos will be made available through a web site so that they can be replayed at the viewer's convenience.
• Video on the Net
  An experiment to gather as much data as possible on video on the world wide web and draw some conclusions from the results.
