Ensemble Juke Box
The Ensemble Juke Box (EJB) is a distributed audio application designed
to exchange high-quality audio data bewteen users on local area networks.
The jukebox can read digital audio data from some cdrom devices, and save
it in files for later playback or play it directly to an audio output device.
This application makes use of the Ensemble group communications system to connect multiple
users on the network, and to provide fault-tolerant behavior during network
outages or computer failures. EJB is a real-time system written in Objective-Caml
(a dialect of ML).
Some of the features of the jukebox include:
- Direct access to compact disc digital audio (CDDA)
- Distributed, broadcast operation between multiple users
- Customizable audio database for each user
- Enhanced protection for audio files
- Access to CDDB (a database of compact disc title information).
This document provides information on installation and operation of the
jukebox, as well as the current status of the project. Currently, the jukebox
runs only on Linux,
and the current release is an alpha release. Our plans include an eventual
port to Windows NT.
The authors of this are Jason Hickey, and Mark Hayden. Jason performs research in programming
languages and formal methods in the Nuprl project, and Mark is the main designer and implementor
of Ensemble, part of the Horus project. Both of us are graduate students at
Cornell University
in the Department
of Computer Science.
