There are a number of competing digital broadcast radio standards in existence
today. These were primarily developed to provide a number of either audio only, or
audio-visual services across a substantial geographical area. Since their conception,
all of the digital broadcast standards have been able to transmit other kinds of
data, known as data services, alongside audio and audio-visual data.
The ability of audio and video codecs to cope with reception affected by error
tends to be much higher than other kinds of digital data. As these standards
were primarily developed to be carriers of audio or audio-visual data, the error
protection for all of the digital broadcast radio standards was designed to be
suitable for the contemporary audio-visual codec; typically the worst expected
Bit Error Rate (BER), after the error protection, is 10-4. This protection is not
strong enough for data that is intolerant of error.
This research analyses and compares the performance of data services sent on
Digital Audio Broadcast (DAB) and Digital Video Broadcast–Hand-held (DVB–h)
channels. [Continues.]
