  • Digital TV Transition and New Video Distribution  Technologies Veena Rawat President, Communications Research Centre Canada
  • CRC is Canada’s Primary Federal Laboratory for R&D in  Advanced Telecommunications Wireless and  Satellite Networks Internet Broadcasting CRC is right in the middle of the  telecommunication convergence! 2
  • Agenda Traditional Broadcasting Transition to Digital TV Digital Dividend Emerging Video Delivery Technologies  Summary 3
  • Traditional Broadcasting Now: Traditional broadcasting in Canada Over-the-air (OTA) (10 % of Household for NTSC) CATV (64%) Satellite (26%) Future: Emerging delivery technologies                Improvement to ATSC DTV Transmission IPTV Internet TV Mobile TV: ATSC M/H, DVB-H, MediaFlo, ISDB-T… Wi-Fi/Wimax 5% of video viewing in 10 years? 10 %? 20%? 50%? 4
  • Traditional Broadcasting Transition to DTV and HDTV well  under way in Canada: Virtually  complete for Satellite and Well  advanced for Cable  Canada decides to let the market  forces dictate the transition for  digital terrestrial TV transmission End of Analog TV Transmission: Transition Completed United States 12‐6‐2009  Transition for Full‐Power only.  LPTV analog Canada 31‐8‐2011  Transition in Progress Mexico    1‐1‐2022   Transition not started yet No transition plan          Europe Recomm. 1‐1‐2012 No information was available 5
  • Terrestrial Digital Television Transition in Canada In 2002, the CRTC set out the regulatory  framework for licensing DTV stations, market  would drive transition In 2007, the CTRC revised its transition policy  (of  allowing the market to determine when  the analogue switch‐off begins) and indicated  a tentative date to shut‐down analog TV by  August 31, 2011 except in northern  communities 6
  • CRTC Announcement on March 22, 2009  (CRTC 2010‐167) There is no change to the August 31, 2011 analog TV switch-off date CRTC requires mandatory DTV conversion for the 31 largest markets by Aug. 31, 2011 – 165 stations The 31 largest markets: 300,000+ population Provincial/territorial capitals Markets served by multiple originating stations to convert to DTV by 2011 TV stations outside the major markets and on channels 52-69 (700 MHz Band) to vacate their channels by 2011 - 20 stations Remaining analog TV operations are “secondary” to DTV after 2011 Altogether about 185 stations out of a total of 750 need to convert to DTV by August 2011 7
  • DTV Arrangements with the USA Exchange of letters between Industry  Canada and the FCC is in place Formalizes our respective post‐transition  allotments/assignments in the border area (360 km)  Provides guidelines on the coordination of new allotments  and changes to the plan during Canadian transition A Treaty Agreement is being finalized: To replace the existing TV agreement and the transitional  arrangements To come into force after both countries complete  transition to DTV 8
  • Television Market (in ,000) World Mexico USA Canada Households 1,800,00 25,000 115,760 13,731 TV households 85 930 23,175 114,500 13,593 Penetration (TV %  65.3 % 92.7 % 98.9 % 99% of households) Penetration (HDTV  6 % ? 44.6% 37% % of households) 9
  • FCC Broadband Plan (USA) FCC hoping to free 120 MHz from digital  television broadcasting spectrum Voluntary basis Broadcasters to share auction revenue with  government (if approved by US Congress). US Broadcasters claimed that they need this  spectrum to support Mobile TV (ATSC‐M/H),  3D‐TV and Emergency Alerting 12 major US TV groups to aggregate spectrum  to offer national mobile TV service  10
  • Transition Issues Has many objectives Technical Cultural Consumer interests Public interests Need to know various jurisdictions/legislations  in a given country Need firm timelines and roadmap for  transition and post transition Urban/Rural phased‐in approach provides  flexibility 11
  • Transition Issues (continued) Rules for broadcasters to use extra capacity available  within their channel (e.g. mobile, TV, Data) ?? Support for Set‐top boxes ?? Simulcast period during transition Termination of availability of analog equipment ?? Timing for use of Digital Dividend ?? 12
  • Digital Dividend 13

  • Digital Dividend: Steps Taken In Canada June 2006: RP‐06: Policy for the use of Television Channels 2 to 59 for  advanced communications services in remote rural communities. (Focus licensing in Channels 25, 34, 35 and 43 initially to help manufacturers  keep costs down and minimize broadcast coordination.) A number of applications were filed (see Figure) Interim Technical Guidelines for Remote Rural Broadband Systems (RRBS)  Operating in the Band 512‐698 MHz (TV Channels 21 to 51) GL‐05 (March 2007) Completion of the Radio Standard Specification: RSS‐196 (March 2010) Publication of the Standard Radio System Plan: SRSP 300‐512 (March 2010) Minimum distance from Canada/US border: 121 km until agreement is  reached between FCC and IC. 16

  • Improvements to ATSC  (Digital TV Over‐the‐Air Transmission Standard) Better Video Compression: MPEG‐4/AVC Better quality : 1080P/60 Hz  (BlueRay) More Robust Transmision Mode Higher Capacity Transmission to Mobile/Handeld: ATSC‐H/M Adding IP data Adding interactivity  Adding non‐real‐time services 20
  • IPTV: Main Features  To broadcasters, IPTV (or Broadband Television) is simply “a new emerging platform for distributing digital television channels to home consumers using a TV screen” To telecom industry, IPTV is synonymous with a new opportunity to take part in an attractive and dynamic media market To content producers, A new way to reach consumers and generate increased revenue and profits Broad range of IPTV services: Standard Def. Television (SDTV) Interactive information High Def. Television (HDTV) Content portability Video‐on‐Demand (VOD) Video clips on‐demand Interactive program guid3e Video calling/conferencing Web browsing on TV Video messaging Music channels Network‐based time & placeshifting Local programming Peer‐to‐Peer Video Voice services Home automation Emergency services On‐line dating Information services Personalized advertising Personal Video Recorder (PVR) Wireless/Wireline Integration 21
  • IPTV: Challenges Business challenges Need to define successful business models Telcos being new players in the TV market Competition for content Technology challenges Bandwidth availability System integration (interoperability issues between  network elements) QOS & QOE Regulatory challenges Now regulates as Cable‐Satellite Needs for restriction on content (since all channels  are on demand thus no capacity restriction) Need for National Regulations (since IPTV could be  distributed internationally like voice) 22
  • Internet TV Video/Television distributed via the  Internet (IP protocol) Point to point connections Not ideal for video delivery (real‐time  constraints) Downloadable software players for PC’s Streaming ‐ client/server model  Download: iTunes, Bittorrent, Napster On demand: You Tube Peer‐to‐peer (P2P) (e.g. Hulu and others) Network capacity often challenged! 23
  • Internet TV: Challenges Delivery on a best effort basis, no QoS Network congestions causes: Latencey due to need to buffer Packet losses Jerkiness in video Limits bit rate ~200‐600 kbps range Link capacity fluctuations Client‐server mode does not scale up very well Multicast: the Internet is not yet multicast enabled “The Web infrastructure, even Google’s [infrastructure], does not  scale. It is not going to offer the quality of service that consumers  expect.” Head of TV technology at Google 24
  • Internet TV Improvements:  Network capacity increasing More consumers have access and subscribe  to broadband connections  Using Peer‐to‐Peer connections (P2P):  Video makes up a significant portion of P2P traffic  (more than 60 percent according to CacheLogic) Good for “popular content” Issues: latency, asymmetrical connections… 25
  • Mobile TV Video/Television delivery to portable,  handheld and mobile devices Mobile IPTV or Mobile internet TV Several competing technologies 3G‐4G wireless networks DVB‐H (TV band) ATSC H/M (TV band) Qualcom/MediaFlo (TV band) DMB (DAB‐TV Band) 26

  • Summary of Video Distribution Techniques Production Distribution Viewers Distribution Rights ! Cable TV TV Transmitters IPTV Satellite  Placeshifting WI‐FI • Wimax Internet • Cellular 31
  • Summary The transition to Digital TV is moving along around the world. The end of analog TV will free some spectrum in the Broadcast bands which will be used for new services. Video is now being distributed by many various means: Cable, Satellite, IPTV, Moble Phone networks, Internet… It opens many interesting issues: How will video delivery shift from traditional to new distribution techniques in the next 5-10 years? Many business, technology and regulatory issues continue to be addressed What will be the impact of this shift on the New Media and Entertainment business? Which priorities do we use to allocate the Digital Dividend spectrum? Different choices by different countries Using DTV for more programs not for more quality (e.g. HDTV) Combining TV and radio services on the same transmitters Offering basic internet access using Data Broadcasting Directly jumping to a mobile internet infrastructure and by-passing a transition to Digital Broadcasting 32
