- 2. Introduction
This paper represents a broadcaster’s
viewpoint on the transition to Digital
Television, with specific focus on the shift
from analogue to digital Over The Air
(OTA) transmission in Canada and the
U.S.

- 4. DTV and the Citizen
Citizens – as media consumers, have
more access to digital media than
ever before.
They have been investing in two
kinds of experiences – immersive
digital media experiences that take
them out of their day to day, and
utility experiences that help them
navigate the day to day.
They have been investing in
unprecedented amounts. In both
kinds of experiences, quality is
important to them. In the case of
immersive experiences, quality is
paramount.
Immersive large screen TV
experiences remain the dominant
mode of media consumption in North
America, with little erosion in the
amount of time spent watching TV
overall, and actual growth in some
areas and demos.
Digital TV is the technology that
delivers those experiences.

- 5. DTV and the Broadcaster
Digital TV replaces analogue
TV in all parts of the system.
It provides opportunities to
create immersive media
experiences that continue to
maintain the dominance of
TV as the primary media
form citizens use.
It provides increased
efficiency in all parts of the
value chain, and options to
deliver a variety of TV
products tailored to the
delivery platform and the
desired outcome.

- 6. DTV and Government
Delivery of digitally enabled
services and capabilities has
become the goal of successful
governments in the 21st
century.
Creation of a digital ecosystem
that is accessible and
attractive to citizens is the key.
Spectrum, as a publically
owned resource, is in focus
both as an enabler of a variety
of digital platforms and as a
source of value creation
(digital dividend) for
governments.
Broadcasting is a traditional
and significant user of
spectrum. DTV provides
opportunities here.

- 8. DTV in Canada and the U.S.
Delivery ecosystem of cable, satellite, OTA
Over the Top (OTT) – TV delivered by
Internet).
Uses the ATSC set of digital TV standards for
OTA. Inherently more efficient than
analogue in spectrum use and transmission
power requirements.
Can deliver a variety of TV formats in a
19.39 MB/s bit stream. One full res HDTV,
an HDTV and one or two SDTV, multicast
SDTV (up to six), plus Mobile/Handheld.
An evolving standard – M/H added in 2010,
interactivity added to the spec in ATSC 2.0,
currently has a standard for the delivery of
3D – discussion of ATSC 3.0
OTA was the primary and dominant method
of delivery of television in North America for
many years. Had been declining in
importance as multichannel offers via cable
and satellite have increased in popularity.
This decline was much more pronounced in
Canada than the U.S., a fact which has
influenced the transition.
The transition is essentially completed in the
US and is well on its way in Canada.

- 9. What is Digital Switchover?
Digital Switchover (DSO) refers to the processes by which we shift the delivery of
DTV to citizens from the legacy analogue system to digital delivery.

- 10. Implications for Broadcasters
DTV/analogue coverage
issues
◦ Digital cliff/ digital footprint
◦ Spectrum pull back
◦ Spectrum co-ord and
frequency issues
Regulatory
structure/measurement
structure is based on OTA
footprint
Broadcaster Business
issues
◦ A replacement medium
◦ Costs for dual operation
◦ Usage decline undermines
R.O.I. (full Cdn transition
estimated at 500M – for 5%
of population???)
10©CBC/Radio-Canada 2012
- 15. U.S. Approach
Citizen and political focus from the start –
Clinton and Gore, Bush and Obama
Relatively high use of OTA as the approach
was being designed (20% in 2009)
Freed up spectrum $$$ part of the Federal
budget ($19 billion for 700 Mhz auction)
OTA networks essentially replicated where
possible
Subsequent focus on maximizing R.O.I.
(HDTV, multi-cast, ATSC-M/H)

- 16. Preparatory steps
Transition started in 1999
Engineering work learning
along the way
◦ UHF vs VHF
◦ “Digital cliff”
◦ SFNs
Consumer Electronic Industry
prep
◦ FCC tuner ruling – March 1
2007
Citizen prep
◦ NTIA Coupon program – $1.3B
◦ DTV.gov, (FCC web site)
◦ Broadcaster obligations - $1B

- 17. Events in the US Transition
Transition defined as Feb 17th
2009 – 6.5M Americans deemed
“not ready” at end of January.
Obama asks for delay - much
political churn but eventually
Senate bill passed with a
“voluntary delay” with much FCC
conditioning.
Roughly 600 stations
transitioned on Feb 17, and the
remainder transitioned June 12,
2009.
Much worry after transition
about people left behind but this
dissipated quickly. Transition is
essentially complete.

“All digital transitions
are difficult but
the US transition was
successful in the end,
in spite of a number
of decisions and
policies that made life
confusing and overly
complicated at one
time or another
for all concerned.”

- 19. Canadian approach
Industry driven within a
regulatory framework (CRTC
for licensing, Industry Canada
for spectrum management).
DTV Task Force 1997.
Policy framework for transition
2002.
CDTV 2002 – 2006.
DSO defined 2007.
By design lagged US transition
OTA usage much lower than
US (estimated at 12% in 2009
and declining – now 5%).
Canadian 700 Mhz spectrum
auction deferred.

- 21. Events in the Canadian Transition
Ended licensing of new analogue stations
in 2007. Defined DSO as Aug 31, 2011.
Forced ASO only in specific “mandatory
markets” or where spectrum/frequency
issues forced it. For the rest, analog
switch off left undefined.
CBC/Radio-Canada at DSO – 24 DTV, 620
analogue. 38 analogues were shut off
because they either replicated or were
replaced by DTVs, or because of the
spectrum pull back.
CBC/Radio-Canada and TVO switched off
analogues July 31 2012.
CBC/Radio-Canada today – 27 DTV, 12
analogue. The 12 are all repeaters
operated for affiliated broadcasters. 608
CBC analogue transmitters shut down.
Other Canadian broadcasters have said
they will maintain their OTA analogue
networks as long as they can do so
economically.

- 23. Two countries, two stories
U.S. has maintained a substantial DTV OTA infrastructure.
Work continues on fine tuning the ROI of that infrastructure
with multicast strategies and with two consortiums working
to develop M/H.
Transition in U.S. seems to be “yesterday’s news”
Canada has eliminated a large part of its OTA
infrastructure, maintaining it in major markets only (for the
most part.) Current activity in both multicast and M/H is
low.
Transition in Canada continues as the future of the
remaining analogues is decided. Early yet to understand
reaction to ASO.
There has been some reaction in both the press and in
academia to the low level of public debate on DSO, as
compared to the U.S. Thus far, this appears to have no
traction.

- 24. In summary
Transition is inevitable.
There are real benefits,
both tangible and
otherwise to doing so.
There are real costs to
be managed.
Technological, social and
economic factors must
be dealt with
simultaneously to get to
the optimum solution.
Solutions are complex
and very specific to the
situation in a given
territory.

- 25. Looking forward
Much discussion about the place of Television in a wired
world. Is OTA media the best use of spectrum as opposed
to expanding the availability of digital broadband
connectivity?
