IPTV for People whoAREN’T Engineersby Shaun CarlsonArvigHow a most Network Engineers feel when teaching the “non-technically inclined”… and how the “non-technically inclined” feel when listening …Alternate Title:“How to talk to a Network Engineer”What to expect from this presentation
  • Don’t expect:
  • to build an IPTV network in your home
  • a network engineer to ask you to fix the DHCP server because STB client leases are overloading the network
  • to shout out the textbook definition to Protocol Independent Multicasting (PIM) on command
  • DO expect:
  • to have basic familiarity with what an IPTV system involves
  • to better appreciate the technical jargon used by your engineering team
  • a network engineer to be annoyed by all of your new questions after this session
  • What is IPTV?One Definition: Internet Protocol television (IPTV) is a system through which television services are delivered using the Internet protocol suite over a packet-switched network such as the Internet, instead of being delivered through traditional terrestrial, satellite signal, and cable television formats.Alternate Definition: IPTV is another way of getting television to the house using a method very similar to delivery of Internet to the home.ITU-T Definition: IPTV is defined as multimedia services such as television/video/audio/text/graphics/data delivered over IP based networks managed to provide the required level of quality of service and experience, security, interactivity and reliability.Some Terms You Might Hear…
