The Communications Research Centre (CRC) is a research and development organization within Industry Canada dedicated to broadcasting technologies. Its mission is to support Industry Canada's spectrum management mandate and enable broadcasters to provide new and improved services. CRC has unique facilities for transmission testing, coverage analysis, and subjective quality assessment. It partners with Canadian broadcasters and universities as well as international organizations on projects related to digital radio/TV technologies, audio/video coding, and quality evaluation. CRC aims to transfer its knowledge and support the transition to digital broadcasting through its research.

Trends
Transition from analogue to all digital broadcasting
All-digital technologies are re-defining broadcasting.
The convergence between Telecommunications, Internet
and Broadcasting systems will accelerate.
More advanced standards are in development.
Broadcast spectrum to be used in a more efficient
manner, by sharing it with other licensed and unlicensed
systems and for the delivery of non-broadcast services
Important regulatory changes will be necessary to
accommodate a more modern vision of the Canadian
communication infrastructure.
Broadcasting will increase its role for public safety needs.

Definition and Role of Broadcasters
Fast evolution of technologies
Changing Regulations
“Broadcasting is entering a new frontier. Structures and formulas
that worked in the past, and are the glue that holds much of the
systems in place, are being challenged by the brutal and unrelenting
force of technological change.”
