Long term impact of our work: An example

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.

Technical Challenges
 Convergence of Computer, Broadcasting
and Telecommunication Networks.
 New applications for Broadcasting
Technologies
 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.”
The House of Commons’ Standing Committee on
Canadian Heritage

2007-2008 Plan
 Extension of Digital Radio Broadcasting (DRB) and Digital
Television (DTV) coverage
 Evaluate the potential of ATSC H/M, DMB, DVB-H, Digital
Radio Mondial (DRM),… to provide mobile and handheld
television services using the broadcasting infrastructure.
 Applications related to multimedia services for delivery by
broadcast as well as other systems such as Wi-Fi, WiMax
 Transfer broadcasting technologies for the development of
new products and services outside the Broadcasting
industry.
 Studies to determine how broadcasting and new
telecommunication systems can coexist in the same
frequency band

VPBT Future
 VPBT resources in 2008-09 ?
 Balance between internal and external resources
(45% of 06-07 VPBT O&M was external!)
 More collaborations: Internal and external
 Between groups within CRC and IC
 Universities
 Private sector
 Other departments
 VPBT in 2012
 Succession plan: New managers, new VP.
 Future R&D Topics

SFN infrastructure

FM-IBOC Tests at CRC
 IBOC transmitters moved to CRC
 Test methodology developed
 10 IBOC receivers acquired
 Test setup configured and refined
 Lab tests now in progress

Software DMB system

Audio Signal Processing
 State-of-the-art Perceptual Audio Codecs (MPEG-AAC) deliver
broadcast quality at a bit rate around 100 kbps per stereo pair
 Would like to reduce that rate to < 64 kbps with Novel Audio
Coding techniques
 RAAS developed a novel coding paradigm labeled as “Spike-
based Audio Coding”

Video Processing
 Simple and efficient 2D to 3D conversion
 Multiview 3D video representation and coding (Collaboration
with ETRI)
 Wavelet-based Image codec (CRC-CWT)
 Performance equals or exceeds that of JPEG-2000
 Wavelet-based video codec (CRC-WVC)
 Performance comparable to H.264
 Frame rate conversion (CRC-FRC)
 Multi-frame motion estimation
 Distributed Video Coding (Université Laval)

Quality Assessment
•Standards: Video Quality Expert Group-VQEG and ITU-R
•Bell ExpressVu, Videotron (Quality of HDTV service)
•NAVIRE (Virtual Navigation in Image-Based
Environment)

Today’s weather.
Korea is expected to be mainly sunny.
And the wave of the sea is rippleless. If you
want more local information, please say your
city.
Seoul will be sunny.
The temperature will be from high 10 to low 3
degree. And the precipitation is 0%.
No accumulation is expected.
Multimodal Applications for Mobile Multimedia
Broadcasting (Collaboration with ETRI, Korea)

Conclusions
• Broadcasting continue to evolve and to play a major role.
• Radio and Television will be one part of an interactive
immersive multimedia experience.
• Contents will be available through various media and
displayed on a variety of devices.
• Ultimate goal is to get anything, anytime, anywhere…
• But each application will find its niche.
• CRC-Broadcasting is helping the department, the
Canadian industry and our international partners to move
toward an harmonious transition to a digital and converged
world.
