IPTV Distribution Technologies in Broadband Home Networks

  1. 1. IPTV Distribution Technologies is Broadband Home Networks IPTV Distribution Technologies in CCECE 2007 Broadband Home Networks Introduction The IPTV network Evaluation criteria Wired distribution technologies Wireless distribution technologies Emad Shihab and Lin Cai Motivation for this work Conclusion and future work Wireless and Networking (WAN) Research Group University of Victoria
  2. 2. IPTV Distribution Technologies is Broadband Home Networks Outline CCECE 2007 Introduction Introduction The IPTV network The IPTV network Evaluation criteria Wired distribution Wired distribution technologies technologies Wireless distribution Wireless distribution technologies technologies Motivation for this work Motivation of this work Conclusion and future work Conclusion and future work
  3. 3. IPTV Distribution Technologies is Broadband Home Networks IPTV and VoD CCECE 2007 Introduction Introduction IPTV: Is television over IP networks. IPTV should The IPTV network ideally offer complete broadcast channels (just like our existing cable TV) Evaluation criteria Two way capability in IP networks allows IPTV Wired distribution technologies interactions among service providers and Wireless distribution subscribers. technologies Motivation for this work Video on Demand (VoD) enables a user to join Conclusion and future work and start any program at their convenience (somewhat similar to Pay per View) Unicast stream of programming with controls like play, pause and rewind
  4. 4. IPTV Distribution Technologies is Broadband Home Networks The Video Headend and Core Network CCECE 2007 Introduction The Video Headend The IPTV network network The video head end is the point in the network where the programming content is captured, Evaluation criteria encoded and broken into IP packets Wired distribution technologies Wireless distribution The Core network technologies Motivation for this The grouping of encoded video streams, work representing the channel line up, is transported Conclusion and future work over the service provider’s IP network
  5. 5. IPTV Distribution Technologies is Broadband Home Networks The Access network CCECE 2007 Introduction The link from the service provider to the individual Introduction The IPTV network network household. It consists of three main components: Evaluation criteria The Broadband Remote Access Server (BRAS) Wired distribution technologies authentication, billing, etc.. Wireless distribution technologies The Digital Subscriber Line Access Multiplexer Motivation for this (DSLAM) work Conclusion and future The subscriber’s home through Digital Subscriber work Line (DSL)
  6. 6. IPTV Distribution Technologies is Broadband Home Networks The home network CCECE 2007 The network inside the home. Ideally it is setup by the user Introduction Used to distribute the signal to all network devices inside the home The IPTV network network To successfully distribute these signals, we can use: Evaluation criteria Wired distribution technologies Wired distribution Ethernet technologies Power line Wireless distribution technologies Phone line Coax Motivation for this work Conclusion and future Wireless distribution technologies work UWB IEEE 802.11x Millimetre Wave (MMW) 57-64 GHz How we use these distribution technologies depends on the home network architecture
  7. 7. IPTV Distribution Technologies is Broadband Home Networks Evaluation criteria CCECE 2007 Maximum data rate: The maximum raw data rate that the respective technology can theoretically achieve is Introduction considered. The IPTV network Cost: Because we focus on the home network, cost here refers to the cost that the end user will face in order to Evaluation criteria Evaluation criteria make use of the technology. We assume that the cost to rewire a home is prohibitively high. We also consider the Wired distribution cost of purchasing additional equipment such as adaptors, technologies access points (APs), etc. Wireless distribution technologies Interference: For broadcast wireless and wired technologies, interference not only affects the channel quality, but Motivation for this work also limits the network capacity. Conclusion and future In-home availability (wired): In-home availability considers work how many outlets are available on average in a typical home. Transmission distance (wireless): This determines the distance that a wireless device can provide coverage for.
  8. 8. IPTV Distribution Technologies is Broadband Home Networks Wired distribution technologies CCECE 2007 Introduction Ethernet The IPTV network Main advantages: Data rates up to 1 Gigabit, reliable connections, employs efficient CSMA/CD Evaluation criteria MAC Wired distribution Wired distribution technologies technologies Main disadvantage: Wireless distribution Required rewiring existing homes (too costly) technologies Motivation for this work Powerline Conclusion and future Main advantages: work Data rates up to 200 Mbps, doesn’t require rewiring the existing home (the most widely available outlets in the home) Main disadvantage: Very noisy channel condition, cost of powerline adaptor is considerably high
  9. 9. IPTV Distribution Technologies is Broadband Home Networks Wired distribution technologies cont’d… CCECE 2007 Introduction Phone line Main advantages: The IPTV network Data rates up to 240 Mbps, no rewiring of the existing home required, the Evaluation criteria latest standard (HomePNA 3.0) supports QoS for multimedia applications Wired distribution Wired distribution Main disadvantage: technologies technologies Most phone line outlets are not located in positions where they can reach Wireless distribution TV sets technologies Motivation for this work Coaxial Conclusion and future Main advantages: work Data rates in excess of 200 mbps, no rewiring of the existing home required, provides QoS support Main disadvantage: Coax outlets are not as widely available as phone line or powerline outlets
  10. 10. IPTV Distribution Technologies is Broadband Home Networks Wireless distribution technologies CCECE 2007 Introduction Ultrawide band Main advantages: The IPTV network Data rates in excess of 480 Mbps, provides QoS support, low interference Evaluation criteria to existing narrowband technologies Wired distribution Main disadvantage: technologies Wirelessdistribution Limited transmission range Wireless distribution technologies technologies IEEE 802.11n Motivation for this work Main advantages: Conclusion and future work Data rates in excess of 500 Mbps, provides QoS support, large transmission range (can provide coverage indoors and outdoors) Main disadvantage: May require new hardware, large transmission range, interference with current narrowband technologies
  11. 11. IPTV Distribution Technologies is Broadband Home Networks Wireless distribution technologies CCECE 2007 Introduction milliMeter Wave (MMW) 57-64 GHz Main advantages: The IPTV network Data rates in excess of 2 Gbps, provides QoS support, low interference Evaluation criteria Main disadvantage: Wired distribution technologies High oxygen absorption, requires LOS paths Wirelessdistribution Wireless distribution technologies technologies Motivation for this work Conclusion and future work
  12. 12. IPTV Distribution Technologies is Broadband Home Networks Motivation CCECE 2007 Introduction Our main goal is to propose efficient home network architectures The IPTV network Before we can propose these architectures, we need to research the latest distribution technologies available for us to Evaluation criteria use Wired distribution Post understanding the characteristics of these distribution technologies technologies, we are in a better position to design efficient home Wireless distribution network architectures technologies Motivation for this Motivation for this The next step from there is to evaluate our home network work work architectures, and further improve our design Conclusion and future work
  13. 13. IPTV Distribution Technologies is Broadband Home Networks Conclusion CCECE 2007 Introduction We have surveyed the leading wired and wireless broadband distribution technologies The IPTV network We evaluated the effectiveness of the respective technologies according to specific criteria Evaluation criteria In the future, we plan to propose and evaluate efficient home Wired distribution technologies network architectures that make use of these distribution technologies Wireless distribution technologies Motivation for this work Conclusion and Conclusion and future work work future
  14. 14. IPTV Distribution Technologies is Broadband Home Networks Thank you! CCECE 2007 Introduction The IPTV network Evaluation criteria Wired distribution technologies Wireless distribution technologies Motivation for this Questions...? work Conclusion and future work
