Digital Audio Broadcasting
Digital Audio Broadcasting started in the UK in 1995, but only now are we starting to see it gaining momentum as Digital One starts to broadcast alongside the BBC. In many areas there are now more digital radio channels available than analogue channels. Now that the commercial interest is starting to match the technical success of the system, it is important to understand the full capabilities of this new digital radio format.
The course is designed to provide a general technical overview of all aspects of Digital Audio Broadcasting.
A large range of material is covered during this course which will suit technical engineers with a reasonable knowledge of general broadcasting principles.

Day 1
9:00-09:30 
Introduction 
An overview of the future of radio 
Peter Shelswell, BBC R & D 
09:30-10:15 
Psycho-Acoustics 
This session will explain the way in which psychoacoustic masking can be exploited in low bit-rate coding of audio signals, with particular  emphasis on sound quality considerations and bit rate requirements  for MPEG audio. Demonstrations of coding artefacts and sound quality options will be provided. 
Dr Francis Rumsey, University of Surrey

Lunch 
14:00-15:15 
Modulation and Coding 
A description of the reasons why COFDM is such an important modulation system. Why simple systems were tried and rejected and how the new format has become a common solution to all transmission systems which use portable receivers. 
Peter Shelswell, BBC R&D 
15:15-15:45 
Tea 
15:45-17:00 
Transmission

Day 2
9:00-10:30 
Receivers 
Receivers are an important part of the system. What are the important features in the receiver itself, and what can we do to help the listener get more value from his or her system? 
David Hawkings or Gordon Chambers, Roke Manor Research Ltd 
10:30-11:00 
Coffee 
11:00-12:30 
Alternatives

    Dave Thompson, ntl 
    15:15-15:45 
    Tea 
    15:45-17:00 
    Future of Radio 
  • Simple text services 
  • Introduction of Pictures
