  • 4. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Overview of Broadcasting Technologies Branch: MISSION To be the primary technical centre of excellence in broadcasting technologies in Canada in order to support the Department in its mandate of managing the Spectrum on behalf of Canadians, and enable broadcasters to provide improved and new services to Canadians by transferring knowledge and technologies. CRC is the only organization in Canada with a R&D program and unique facilities dedicated to Broadcasting
  • 5. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Organisation Vice-president: B. Caron (D. Wang) Resources Employees : 42 + 8 Term ($4.85 M) A-Base O&M: $950 K External revenue: $445 K
  • 6. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Future technology issues for broadcast/multimedia  DTV Transition in Canada  Transition to Digital Radio: FM-IBOC, DAB+, DRM+  Future use of TV Spectrum:  Mobile TV  Wireless Broadband Access  Radio (DRM+)  White Space devices  Telecom using Broadcast technologies (e.g. MediaFlo)  Implementation of ATSC Mobile TV  Development of ATSC 2.0 and Next Generations of ATSC  Development of 3D Video and Super HDTV  Impact of FCC Broadband Plan on Broadcasting  Impact of Convergence  Internet Enabled TV  Availability of Portable devices with Broadcast services built-in  Software Defined Radio Implementation of Broadcast Standards  Closure of CAB and replacement by TCC  MediaFlo suspending new sales  CRC contribution to new Private broadcasters Technical Coordinating Committee (TCC)  Open Mobile Video Coalition's Washington DC Consumers Showcase
  • 7. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Possible Scenario for TV Broadcasting  Over-the-air (OTA) Digital TV-HDTV is available in all large Canadian cities.  The ‘Hybrid model’, just approved by the CRTC, could be used to provide DTV- HDTV in other areas by offering basic satellite and cable tier for free  The DTV multiplex could be used to offer many Standard Definition channels from only one transmitting station: CBC, CTV, Global, …sharing the multiplex of one transmitter or TVO transmitting 5 different educational programs.  Since most people receive HDTV through Satellite-Cable-IPTV-Internet; Broadcasters start using their OTA facilities for Mobile TV: Local Standard Definition TV to Portable and Mobile devices.  Freed bandwidth in the broadcast band (AM-VHF-UHF) could be used by new service providers. Some may use Broadcasting technologies (one-to-many) to do so. Interference is an issue, for mobile services in particular.  Internet-enabled TV sets will be used to access audio-video content from Internet (e.g. TOU.TV), OTA and BDU.
  • 8. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE 2011-2012 Operational Plan  Improvement to Digital TV and Radio Broadcasting coverage  Improvement and assessment of audio-video quality  Evaluate the potential of ATSC M/H,FM-IBOC, FM-RDS, Digital Radio Mondiale (DRM),… to provide mobile and handheld services using the broadcasting infrastructure and spectrum.  Studies to determine how broadcasting and new telecommunication systems can coexist in the same frequency band (e.g White Space, Public Safety)  Applications related to multimedia services for delivery by broadcast as well as other systems such as IPTV, Wi-Fi, WiMax  Transfer broadcasting technologies for the development of new products and services inside and outside the Broadcasting industry. (See end of the deck for additional slides on links with SITT/CRC Priorities)
  • 9. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Panel Members’ views: Emerging Technical Issues  Sharing the DTV multiplex among different broadcasters is interesting only if it can support more than one HDTV program or if SD quality is acceptable (e.g. TVO)  Distributed Transmitters Networks essential to improve coverage and spectrum efficiency  DRM+ promising to add radio stations in the FM band  Potential of ATSC DTV to distribute Radio services  Issues surrounding the distribution of audio-video contents over various platforms: Broadcast, Cable, Satellite, Internet, LTE, Wi-Fi, Wi-Max…
  • 10. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Panel Members’ views: Relevant developments  ATSC Mobile TV will be successful as it does not require new spectrum and is to be available free.  FCC offer of money to the US broadcasters will be met by a mix response since business opportunities is different for each organisations and specific regions.  The new private Broadcasters’ Technical Coordinating Committee (TCC) is a continuation of the now closed Canadian Association of Broadcasters (CAB) with the Digital Radio Coordinating Group (DRCG) and the DTV Technical group continue to be the technical fora for all the participants involved in broadcasting: Private and Public Broadcasters, Manufacturers, CRC, CRTC, IC
  • 11. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Panel Members’ views: Technology issues for CRC  Is VPBT on the right track overall ? YES  Are there areas CRC should pursue ?  Coexistence of DRM+ with FM  Distributed DTV Transmitters Network to improve coverage and spectrum efficiency  Assess performance of ATSC Mobile TV  Support to a possible Mobile DTV Market Trial by the Canadian industry  Study Media Accessibility for the Hearing and Visually Impaired  Issues surrounding the distribution of audio-video with various communication systems: Broadcast, Cable, Satellite, Internet, LTE, Wi-Fi, Wi-Max…  Optimisation of spectrum use  Are there areas CRC should drop ?  Lower priority on Wi-Fi Hot Spots for Digital Broadcasting repeaters  Specific investigations on channel 5-6 for digital radio allocation
  • 12. CommunicationsResearchCentreCanada COMMUNICATIONS RESEARCH CENTRE Panel Members’ views: Technical panel mode of operation  Share membership list with all members  Share minutes of panels and council meetings with all members.
