Abstract
Timely and clearly transmitted information about the nature of threats is a basic
tool to assist the minimization of consequences of extraordinary events from the
point of view of both prevention of loss of life (e.g. in a form of evacuation) and
minimization of damage to property (i.e. by implementing protective measures in
the threatened area). Informing the population is realized in many available ways
and by many available means, e.g. by nationwide networks of television and
radio stations, by public address systems in towns, municipalities and facilities or
by portable public address devices. However, a significant problem emerges in
the course of evaluation of efficiency of these means especially in the area of
audibility and intelligibility.
The aim of the article is the presentation of a new way of informing the public
in the course of extraordinary events using the existing DVB-T infrastructure.
For this way of informing, an appropriately equipped broadcasting station and
installation of an encoder between the broadcasting station and a multiplexer are
necessary. The stated solution thus will make it possible to add information in
voice to TV or radio broadcasting. This information then can be received by
television (after adding an additional decoder) and radio receivers, which
provides the high intelligibility of transmitted information.
