Digital audio broadcasting transmits interference
free sound of cd quality. Analogue will never be of the same standard
and digital radio will replace AM and FM stations.
Digital radio allows easy tuning and will automatically switch
to the most powerful signal without interruption for the best
possible sound quality. Pay Radio provides subscription services
for live concerts and a digital radio can be programmed to select
a particular music format. Music can be requested by song title,
lyrics or artists and services such as traffic and weather reports
can be selected automatically. Paging and text services are possible
through digital radio and it will be possible to obtain complementary
information about products.
Looking to the future, consumers may be able to transmit and
receive data downloads and fax transmissions through digital radios
and opportunities exist for new revenues through data transmission
services using LCD displays. It may also be possible to download
special product discount information onto a card, which can then
be taken to a shop where the discount can be redeemed on that
product.
Digital radio is an intelligent communications medium that offers
more services than conventional analogue technology. It receives
both satellite and terrestrial based signals and as manufacturing
costs fall, digital radios will be very affordable and efficient
devices for the consumer. For producers digital audio broadcasting
can reduce equipment costs as digital units could be shared between
the stations that use them.
