looking at itunes
Looking at iTunes
  • Rating, Feedback
  • Search, Categorization
  • Collaboration
  • Party Shuffle
  • Smart Playlists
  • AirTunes
  • iTunes is smart and loaded
  • …and so are its clones
itunes shortcomings
iTunes shortcomings
  • AirTunes can play only one channel
  • Party Shuffle can’t be easily configured
  • iTunes players can’t network
  • iTunes can’t be easily extended
  • Smart Playlists can only take you so far
  • No remote capabilities
in addition
In addition
  • What if you could play music from any computer on any computer?
  • What if you could train an agent to select music to play for you?
  • What if you could have a player that could be used to make you feel like a radio DJ – only without the work?
our solution musebox
Our Solution: MuseBox
  • Muses: Agents that pick your music
  • Channels:As many as you like – anywhere you like.
  • Interface:Thin client.
how it works
How it works:
  • User creates a channel on a server
  • User assigns an output to the channel
  • User assigns a muse to the channel
  • The muse picks a song for the channel to play
  • The channel plays that song on the assigned audio output.
muses
Muses
  • A muse is a channel’s source of inspiration.
  • DirectoryMuse is inspired by a directory
  • MySQLMuse retrieves song info from a DB
  • RequestTakerMuse waits to hear from user
  • MasterMuse can delegate work to all the muses according to a ranking system (and whatever muse is willing to inspire)
outputs
Outputs

Local Outputs

  • Java Media Framework (all platforms)
  • Delegation to mpg123 (nix)

Streaming Outputs

  • Icecast (nix to all platforms, multiclient)
  • JMF/RTP (all, single or multiclient)
  • Faux-Stream [download, play, delete] (all, single)
interface
Interface
  • Built-in implementation of HTTP1.0
  • Entirely in HTML
  • Plain interface gets created by objects
  • Advanced interface uses HTTP.Template (java port of HTTP::Template)
  • XML interface might connect real GUIs(much like mldonkey works)
  • Can you really have an mp3 player in HTML?
