Connecting What’s Next

  • Electricity prices increased of 6.3% between

2010 & 2011

  • Continued to increase 6.6% between 2011

and 2012

  • Projected to continue to rise throughout the

world, increasing by as much as 60% by 2030

Issues Customers Are Facing

  • Some countries have imposed energy taxes

based partly on carbon content

  • In Australia the carbon tax in 2012 was at

$23 per tonne of CO2 emissions

  • Broadcast Australia estimated the first year
  • f the new tax cost them almost $3M

Connecting What’s Next

There are a number of options for operations and maintenance including

  • Broadcaster provides internal staff to conduct the work, often the case for commercial broadcasters
  • A managed service is used, often the case for multiplexes which have multiple broadcasters, e.g. DAB+
  • A mixture where the operations aspects are conducted by the broadcaster but maintenance is done by a

contract organization, this occurs in large metro transmission sites as well as remote sites

Reduced Service & Maintenance Cost FM, DRM+ and DAB+

Connecting What’s Next

  • Transition period from analog to digital for Radio is longer than for TV
  • Additional costs of transmission during the simulcast period will be approximately

10% -15% more relative to FM operation for each program provider.

  • Broadcaster may not be able to compensate all additional costs of simulcast
  • peration by more revenue

1. Simulcast costs are critical for acceptance & motivation of broadcaster 2. Clear road map of analog to digital transition helps to secure planning 3. Cost compensations for broadcaster during simulcast period Simulcast period most costly for program provider
