MediaNet: A High Performance Platform for Network Media Processing
MediaNet combines 3 technologies developed by researchers at Cornell to
develop a flexible, high performance testbed for storing, transporting,
processing, and using multimedia data. MediaNet combines:
- 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.
Funding for the project is provided under contract N00014-95-1-0799 as
part of the Intelligent Collaboration and Visualization program of the DARPA Information Technology Office
