Transcript

  • 1. VIDEO RELAY SERVICEPRACTICES ANDPOLICIES AROUND THEWORLDC. Vogler1, J. McWhinney2, P. Harper3, A. Raike4, G.Hellström5, G. Vanderheiden61Gallaudet University, 2Significan’t, 3Australian Assoc.of the Deaf, 4Aalto University, 5Omnitor, 6Trace Center
  • 2. What are Video Relay Services? Optional: Audio patch-through (voice carry AEGIS persona: over, hearing Tomasa Almaraz carry over)
  • 3. Relay Services as Enablers• Relay services enable functional equivalence• An attempt at a definition: Can deaf* people use telecommunication services in the same unrestricted manner and at the same costs as hearing people? * “deaf” is meant to include deaf-blind, hard of hearing, and people with speech disabilities, as well here
  • 4. Relay Services in Context• Real-time or near real-time: • Video Relay Services (~50% share in US in 2010, >60% in Sweden) • Captioned Telephony (~ 20% share in US in 2010)• Interactive, but with significant lag • IP-based Text Relay • Analog TTY Relay • Speech To Speech
  • 5. VRS Across the World• Currently not interoperable – video call side does not work across national boundaries• Per-country differences in technologies and policies• The following slides compare some key aspects of VRS across nine countries• Full matrix can be found at http://tinyurl.com/VRSComparison
  • 6. VRS Standards and ProtocolsApplies when a deaf person calls a hearing personvia VRS via a video connection SIP H.323 H.324M ProprietaryAustralia X (Skype)Denmark X XFinland X (likely)Germany X X X (Web)New Zealand X XNorway X X X X (Skype)Sweden X X X (Web)United X X (SignVideoKingdom only)United States X X (FaceTime, Web)
  • 7. VRS Standards and Protocols• It is a Wild West out there• No common interoperable protocol • This is a huge problem for point-to-point calls • Severely limits the ability of mainstream equipment to make video connection to VRS• There is pressure to move toward SIP (also for next-gen emergency calls) • Note: SIP alone does not guarantee interoperability, also need common set of codecs, and peering arrangements with proxy server operators
  • 8. Hearing Person Calling Deaf VRS User ENUM E.164 Verbally give (direct dialing of number, handle, deaf user’s or SIP address number) to relay interpreter Australia X Denmark X Finland X Germany X New Zealand X Norway X Sweden X Switzerland X United Kingdom X United States X
  • 9. Hearing Person Calling Deaf VRS User• In almost all countries, relay calls are still too complicated to set up for hearing callers• USA and UK are the only exceptions • There a hearing caller just dials a telephone number normally, and is routed through an interpreter automatically
  • 10. Emergency Calling through VRS Can use VRS to Caller location Priority given call support over normal callsAustraliaDenmark XFinlandGermany XNew ZealandNorway XSweden X X (only REACH X (only REACH 112) 112)United KingdomUnited States X X (but technical X differences across providers)
  • 11. Emergency Calling through VRS• In some countries calling emergency services through VRS is impossible• Most countries do not support caller location • VRS interpreter must ask the caller, and then consult directory to find appropriate PSAP• Most countries do not support priority in caller queue • VRS has no idea that the caller wants to dial 112/999/911, with disastrous consequences if many callers are ahead in queue
  • 12. Policies Guiding VRS Availability• From strongest to weakest: • Functional equivalence • Only restrictions are technical and human factors (e.g. availability of interpreters, types of calls supported by relay service technology) • Access to telecommunications • May be subject to “reasonable accommodations” provision, such as limited talking time, no nighttime calls, extra cost to caller, etc. • Social services • Typically covers labor market participation of people with disabilities with state funds with a set number of interpreting hours/year, subject to bureaucratic needs assessment
  • 13. Policies Guiding VRS Availability Functional Access to Social Service Equivalence TelecomAustralia X (text relay only, VRS TBD)Denmark XFinland XGermany X (personal) X (business)New Zealand X (funding limits)Norway XSweden XUnited Kingdom X (personal) X (business)United States X
  • 14. Operational Policies for VRS Limited Limited Extra Cost Mandated hours weekdays to Deaf by Law Callers Australia X X Denmark X X X Finland X X X Germany X X X X New X X X Zealand Norway X X X Sweden X Implicit United X X X Kingdom United X States
  • 15. Summary and Conclusions• Need for technical standards• Need for integration into ENUM E.164• Emergency access is lacking • Also need to consider next-gen emergency, e.g. REACH 112, NG-911• The differing philosophies underlying VRS show in the operational characteristics • Limited availability in many countries • Extra costs to callers in some countries
