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
