  2. 2. Agenda g • Video Basics • The Internet & IP • IPTV • Internet TV • What’s next? Page 2
  3. 3. Information Transmission • Information Must Converted to be Converted to b C t be Compatible with th M di tibl ith the Medium – Voice -> PCM -> TDM – Video -> QAM -> Coax > > • Various Methods of Conversion – Improve Efficiency – Allow Processing – Provide for Error Correction Page 3
  4. 4. Information to Transmit • Communications Networks Transmit Many Forms of Information F fI f ti – Voice – Video – Web Pages – Documents – Telemetry Signals – Music – Text Messaging Page 4
  5. 5. The Internet • Widespread Use of the Internet has Made the Internet Protocol (IP) the Transmission of I t tP t l th T i i f Choice – Global Access – Inexpensive Transport – Adapted to use with time-sensitive traffic time sensitive Page 5
  6. 6. IP – Some of the Basics Page 6
  7. 7. History of the Internet y • Created by US Department of Defense in 1969 • Wanted a communication system that could not be destroyed by a catastrophic event Page 7
  8. 8. Internet History y • 1957 ARPAnet The Th geography of the growing h f th i ARPANET in June 1975. The network has 57 nodes. Page 8
  9. 9. OSI Model • No Network Discussion is Complete without Mentioning the M ti i th OSI Model M d l • OSI = Open System Interconnection – D fi Defines a networking f ki framework f i l k for implementing i protocols – Uses seven layers Page 9
  10. 10. OSI Model Translating and Coding Policing o c g Data broken down into manageable chunks Adds addressing information Data is packaged into frames Page 10
  11. 11. What is IP? • Internet Protocol (IP) – Method (or protocol) by which data is sent from one device to another • Each computer on a network (such as the Internet) – At least one IP address – Unique ID(s) • Information (email, Web page, video, etc.) is divided into little chunks called packets. Page 11
  12. 12. IP Addressing (Cont) 10110101 . 00111100 . 00001010 . 10001100 First Bits Used to Last Bits Used to Define the Network Define Client On Network Like the Zip Code Like the Name or City Note: Larger cities need more bits to uniquely id tif th i citizens. i l identify their iti Page 12
  13. 13. Options p • Deliver the Packet – Don’t Care about Errors – User Datagram Protocol (UDP) • If the Packet has Errors, Request Another Until is Correct U til it i C t – Transmission Control Protocol (TCP) Page 13
  14. 14. UDP Communications • UDP – User Datagram Protocol – No guarantee of delivery – When is this useful? Page 14
  15. 15. TCP Communications • TCP – Connection oriented – Guaranteed delivery – When is this useful? Hey you! I am gonna send you data ` Hold on a second. I am busy OK PC 2 PC 1 Okay, go ahead and send Here ya go! DATA DATA DATA Hey, I missed part of that last data No problem. I will re-transmit it Okay, now I received it all Page 15
  16. 16. Video Basics Page 16
  17. 17. MPEG-2 Video Frames • I-Frames – C d d using i f Coded i information present only i th f ti t l in the frame it lf itself • P-Frames – Coded with respect to the nearest p p previous I or P Frames • B-Frames – Use both future and past frames as a reference Page 17
