Proceedings from the ABU Digital TV Symposium March 2007.
HDTV IMPLEMENTATION SESSION.
HDTV is being accepted by many in the industry as a killer application for digitalisation. Equipping broadcast facilities within the Asia-Pacific region to become HDTV capable must now be a serious consideration. Such issues will be discussed during this session
Although radio is the last electronic mass medium to be making the conversion to digital transmission, the conversion is well underway with HD Radio1 signals on-the-air in virtually every major market in the United States.
The Eureka-147 DAB system provides a reliable digital broadcast service in excess of 1.2 Mbits/s. It is also suitable for mobile besides portable and fixed radio receptions. Its robust, high spectrum- and power-efficient technology makes it an ideal system for both audio and data transmissions. This paper discusses some of the interesting case studies on the new services and applications by leveraging on the strength of DAB - bringing it beyond its traditional role in audio broadcasting.
Digital HD Radio is being used for many unique new applications in the world - including non-traditional broadcast uses. This presentation will highlight some of the new business models which may help stations "bridge the reciever void" and make digital radio pay before the receivers are in wide distribution.
In October, 2002 the U.S. Federal Communications Commission (FCC) authorized In-Band, On-Channel (IBOC) digital transmissions for all AM and FM Broadcast stations.
The advent of HD Radio is a challenge for radio
programmers and production teams. Not only does HD
open the way for program associated data such as main
program service and station information services, it
creates a new channel for distributing advanced
application services which include multimedia
functionalities. Scheduling play-lists and broadcasting
programs for such an enhanced radio network require
that production teams implement new types of digital
content production workflows. This paper details these
production challenges and offers possible solutions
based on case studies of radio broadcasters that have
been faced with similar issues for other digital radio
broadcasting platforms.

The contents of this paper will include a discussion on HD Radio and how it differs from each of these technologies, in particular relating to their fundamental elements; the audio codec, frequency of operation, modulation and error correction methods, implementation and operation costs, market opportunity, costs and availability of radio receivers.
Digital FM Radio is going on the air worldwide – throughout the Americas as well as in Europe and Asia. Since radio is a mobile media, what are the results in terms of mobile listening? How does HD Radio perform in heavy multi-path areas, and in weak signal areas? What are the ramifications of adjacent channel interference and in conditions of serious over-modulation as is sometimes practiced in Asia?
