FS-VDSL Overview

• Launched in Paris, July 2000
• Target end-to-end video-centric platform
  specification to be published in May 2002
• Scope includes architecture, video elements,
  protocols, customer equipment functionality, VDSL
  transceivers, operations
• Successful verification of specifications via
  international system demonstrators hosted by
  operators
• Leverage end-to-end interoperability
• FS-VDSL Committee has joined ITU in 2002 as a
  focus group attached to SG16
• Despite the name, FS VDSL addresses all DSL
  technologies capable of supporting video delivery
  (ADSL, ADSL2, VDSL)

Service definition

• Service definition has been provided by the
  operator group
• Three service category
• TV based services
• PC based services
• Voice services
• Various combinations of theses elementary
  services can be offered
• Content security (Access control, content
  encryption, conditional access and digital right
  management) identified as key to deliver these
  services

7
Service definition TV based services

• Broadcast TV and audio, up to three channels
• HDTV
• Pay per view
• Video on demand
• Search engine
• Video control pause, fast forward
• Electronic Program Guide
• Picture in Picture, Picture in Browser
• PVR
• Interactive TV browsing, mail, chat
• Video quality equivalent to cable or satellite
  and additional services

Service definition PC based and Voice services

• High speed Internet access including email
• Live TV using  PC  technologies
• Video on demand
• Video conferencing
• Interactive games
• Need to support connection sharing
• Bit rate for the Internet access up to 3Mbits/s
  for residential
• Bit rates for video in the range 300-750 kbits/s
• Voice service description is light, based on
  derived voice

System Architecture and CPE

• A specific terminology has been introduced to
  avoid confusion between modem, gateways,
  residential gateways .
• The SA and CPE group has defined
• End-to-end protocols to support basic
  connectivity and basic function
• The use of an hybrid modem performing both L2 and
  L3 functions
• CPE and network behaviors to support access to
  several IP networks
• Main choices
• Use of ATM as layer 2 over DSL
• Core network flexibility
• Distributed and centralized environment for the
  CPE
• Consideration of an  Ethernet-like  home
  network
• No selection of an home network technology
• Transport of the video is coding-independent

System Architecture and CPE Reference model

System Architecture and CPE Possible networks

System Architecture and CPE IP networks

• If the services are provided by different service
  operators, each one will need IP connectivity
  with the device accesing the service on the user
  side

Conclusion

• There is not only one definition of triple play
• The exact set of service will differ from one
  country to another
• H610 defines a set of functions and tools to help
  the setup of triple play services
• H610 is
• Video centric
• Considering DSL technologies, mobile network are
  out of the scope
• Service interactions are not considered in detail
• SG16/QB plans to investigate in this direction
