Streaming media
•is media that is consumed
(read, heard, viewed)
while it is being delivered.
The distinction is usually applied
to media that are distributed over
        computer networks;

The word "stream“
is also used as a verb,
  meaning to deliver
   streaming media.
Who can benefit from
 Streaming Media?
Everyone can benefit
from Streaming Media
At Streaming Media
Hosting, our motto is
"If it can be captured,
 it can be streamed"
One of the most common
ways to distribute internet
  radio is via streaming
    technology using
   a lossy audio codec
Popular ones are:

• The MP3 codec
• Ogg Vorbis
• Windows Media Audio
• RealAudio
• HE-AAC
(sometimes called aacPlus)
The bits are "streamed"
over a TCP/IP connection,
  then reassembled and
  played within about 2
         seconds.
Therefore, streaming
    radio has about
a two-second lag time.
There are three major
components to an audio stream

• Audio stream source
• Audio stream repeater (server) ex*Abacast

There are
 many methods
  for creating
the audio stream
     source
First one is;

   • The Opt for the SHOUTcast
       service, which utilizes
  Winamp and the SHOUTcast DSP
    plugin to ...
Other methods

• Open source technologies such as
  Streamcast, stream-db, IceS, and MuSE,
  and patent-free data formats ...
Two of the most popular internet
radio networks are:

           • Live365
          • SHOUTcast
Open source alternatives include
Ogg Vorbis streamings like;

•Icecast
•Xiph.org,
These internet radio servers
     list thousands of
  Internet radio stations
           covering
    an ever-expanding

The purpose
of the server is
to repeat the stream
 source to the audio
  playback software
Another popular method of

 their streams at a
 lower bitrate have
lower audio quality,

There are also a small number
  of web radio programs that
 allow users to rate the songs
     they are listening to.
The programs are:

•iRATE radio
• Last.fm
• Radio Paradise.

DESCRIPTION Streaming media is media that is consumed

  1. 1. DESCRIPTION
  2. 2. Streaming media •is media that is consumed (read, heard, viewed) while it is being delivered.
  3. 3. The distinction is usually applied to media that are distributed over computer networks; most other delivery systems are either inherently streaming (radio, television) or inherently non-streaming (books, video cassettes, audio CDs).
  4. 4. The word "stream“ is also used as a verb, meaning to deliver streaming media.
  5. 5. Who can benefit from Streaming Media?
  6. 6. Everyone can benefit from Streaming Media
  7. 7. At Streaming Media Hosting, our motto is "If it can be captured, it can be streamed"
  8. 8. One of the most common ways to distribute internet radio is via streaming technology using a lossy audio codec

  14. 14. First one is; • The Opt for the SHOUTcast service, which utilizes Winamp and the SHOUTcast DSP plugin to deliver MP3 audio at higher bitrates
  15. 15. Other methods • Open source technologies such as Streamcast, stream-db, IceS, and MuSE, and patent-free data formats such as Ogg Vorbis. • Using open source stream source tools allows for interesting web interface possibilities like phpStreamcast.
  16. 16. Two of the most popular internet radio networks are: • Live365 • SHOUTcast
  17. 17. Open source alternatives include Ogg Vorbis streamings like; •Icecast •Xiph.org,

  20. 20. to repeat the stream source to the audio playback software
  21. 21. Another popular method of listening to internet radio is: • Using a virtual tuner, which is basically a site that aggregrates links of internet radio broadcasts from around the World
  22. 22. The virtual tuner • Enables the listener to easily find internet broadcasts by genre, language, or location. • To establish a peer to peer connection with the internet radio broadcaster's web server. • avoids re-broadcasting the internet broadcast, thus avoiding the infringement of the broadcaster's copyrigh
  23. 23. ON THE COMMERCIAL SIDE:
  24. 24. It established itself as a market leader with the most reliable set of links to the broadcast urls and that has created the largest aggregation of broadcasts with over 7,800 worldwide is Vtuner.
  25. 25. Some sort of audio playback software or hardware, that is capable of reading HTTP data streams, is needed to listen to streaming MP3 audio.
  26. 26. AND
  27. 27. Some popular software players are • Winamp for Windows • iTunes for Macintosh • Microsoft Windows, and XMMS on Unix/Linux.
  28. 28. ON THE COMMERCIAL SIDE:
  29. 29. Listening to internet radio through hardware devices has not been very popular in the past, due to the limited number of devices on the market
  30. 30. BUT • The availability of such devices and their consumer polularity is expected to increase significantly during 2006
  31. 31. • A list of commercially available devices is available at Internet radio device, But Many of these are limited in which audio codecs they can use and consequently the variety of internet radio stations they are compatible with.
  32. 32. AS A DISADVANTAGE
  33. 33. Stations that encode their streams at a lower bitrate have lower audio quality,
  34. 34. BUT
  35. 35. AND AS AN ADVANTAGE
  36. 36. They are more accessible to listeners with a dialup connection, and they can serve more simultaneous users on a given upstream pipe
  37. 37. There are also a small number of web radio programs that allow users to rate the songs they are listening to.
  38. 38. The programs are: •iRATE radio • Last.fm • Radio Paradise.

  40. 40. HISTORY •Display media date back to mid 20th century •High Cost •Limited Capacity •Experiments in 1970s •1980s computer became public to display various media •Enoug CPU power, postponed with low latency interrupt
  41. 41. STREAMING BANDWIDTH& STORAGE • megabytes, gigabytes, terabytes • storage size (in megabytes) = length (in seconds) · bit rate (in kbit/s) / 8,388.608 • (since 1 megabyte = 8 * 1,048,576 bits = 8,388.608 kilobits) • As a Real World Example: • One hour of video encoded at 300 kbit/s (this is a typical broadband video for 2005 and it's usually encoded in a 320 240 pixels window size) will be: • (3,600 s · 300 kbit/s) / 8,388.608 = 128.7 MB of storage • if on-demand streaming server and by 1,000 people: • 300 kbit/s · 1,000 = 300,000 kbit/s = 300 Mbit/s of bandwidth
  42. 42. PROTOCOL ISSUES 1. A network protocol to support streaming media • Datagram protocols • error correction techniques • Dropout 2. The Real Time Streaming Protocol (RTSP) 3. Real-time Transport Protocol (RTP) 4. Real-time Transport Control Protocol (RTCP) 5. Peer-to-peer (P2P) protocols arrange for media
  43. 43. COST BENEFIT ANALYSIS OF RADIO STREAMING • Our goal is to serve a qualified streaming at low cost. • eliminate those hardware costs →increase our potential benefit →customers get higher satisfaction
  44. 44. COST BENEFIT ANALYSIS OF RADIO STREAMING • Radio Koc, Cetin Tunca – Limited number of clients (20-25) – Quality of the streaming not so high • only two servers – depends on the hardware components • Radio Automation Packages – DRS2006 http:www.drs2006.com • qualified streaming system at low cost • changing prices according to the bandwith and storage capacity
  45. 45. TESTING ISSUES • Widespread deployment of streaming media (Testing service deployment) • Test domains; – Scalability – Quality of Service – Quality of experience – Protocol conformance
  46. 46. SOCIAL & LEGAL ISSUES • Recording streams, a significant issue in the application of law to cyberspace. • no way to prevent • make it inconvenient – using unpublished data formats – encrypting the stream • make it illegal – Copyrights – Patents – license agreements
  47. 47. DESTREAMING • the process of recording streaming media onto a computer • A way of saving multimedia streams • Stream content providers' proprietary software is often poorly coded, and, even worse, can contain spyware.
