					 Streaming technology primarily put
 to major use in mid to late 90’s
 › Due to:
    Increased bandwidth
    Growing use of the internet
    Standardization of protocols
 Two   types of media streams
 › On-demand
 › Live
 Content   can be stored in 1 place
  › Saves disk space
 Noneed to fully download the media
 before playing
  › “On the Fly” – Media can be played
    and downloaded at the same time
 Share content with people outside of
  network
 Earn revenue with ads in radio station
 Streamingcan be broadcasted via
 TCP or UDP
 › TCP ensures message delivery
 › UDP does not insure delivery
    Faster, but lower quality, less features
 › Both protocols are part of the Transport
   Layer in the OSI Model
 Applications:
  › Web
  › Email
  › FTP (File Transfer Protocol)
  › SSH (Secure Shell)
 Applications:
  › DNS – Allows for unique computer
    names on a network
  › IPTV
  › VoIP
  › Trivial FTP (TFTP) – less secure
 User   selects from content on server
  › Content is stored on server
  › Available for long periods of time
 User gets content that the
  server/admin chooses to send
 User cannot change content
 Universal Plug & Play
 Type of On Demand Streaming
 Allows for media from a source to
  “broadcast” locally in a network to
  “receivers”
 Receivers are able to see directory
  information and begin playing
  when a file is selected
 Centralizes media
 Allows for non-traditional PC
  devices to connect to media
  › Playstation 3
  › Xbox 360
  › Digital Picture Frames (high end)
  › Peripherals
  › Media Players
 Major   Pieces:
  › Content (songs, podcasts, mic)
  › Winamp
  › Shoutcast DSP Plugin
  › Shoutcast Server (DNAS)

 Content   may need licensing
  › Especially if used to generate revenue
 Download   the software:
 › Winamp
 › Shoutcast DSP Plugin
 › Shoutcast Server (DNAS)
 Install   software in the following order:
  › Winamp
  › Shoutcast DSP Plugin
  › Shoutcast Server (DNAS)
 Run & Configure Shoutcast Server:
 Click on *Edit Config*
 You should get a text file
 Main      configurations:
    › MaxUser=32
    › Password=password123
    › PortBase=8000

 Save      changes!

   Read file for explanations on how
    to make other changes
 Run Winamp
 Configure Shoutcast DSP Plugin
   For address, leave as
    localhost

   Port should match what was
    set in Server (8000)

   Password should be same as
    Server (password123)

   Check “Automatic
    Reconnection on
    Connection Failure” &
    “Connect at Startup” boxes
   Use Encoder 1 to determine
    the quality that your music
    will be broadcasted

   96kbps, 44.1kHz, Mono is a
    good setting

   Remember that if you
    choose to higher the quality,
    it will be multiplied by the
    number of listeners
    (may make it choppy for
    everyone)
   Yellowpages allows server to communicate/advertise
    on Shoutcast’s servers

   Output 1 is for a single instance of Winamp. You can
    setup multiple instances (servers) with multiple
    outputs --(IF your hardware can handle it)

   You can also choose a different
    device
    (such as your soundcard,
    which you can use a microphone
    to become a talk show host)
 Make  sure the Shoutcast Server is
  running (you may have to restart
  program after making changes)
 Make sure Winamp & DSP is running


 Nowyou can add songs to playlist
 and begin playing & broadcasting
  › You can save playlists & make sure
   you have some kind of loop selected
