Enjoy Noise-Free Audio via DAB Radio
October 23, 2007
Listening to music through radio is a good entertainment though there are high end musical devices introduced in this electronic world. DAB radio is one, which uses unique technology for broadcasting audio signals. Digital radio transmission takes place at the time of broadcasting audio signals in DAB radio. Technical experts use the term “Eureka 147” for DAB radios.
Digital transmission technology was initially encouraged to get more stations with impressive audio quality. The UK is one of the market leaders in manufacturing DAB radios. DAB is an acronym of Digital Radio Broadcasting through which listeners can enjoy digital audio sound. When you have DAB Radio at your home, you can tune more stations than FM Radio.
Brief Flashback
The first trail broadcasting was made in the year 1990. The UK was relayed first public broadcasting in 1993. A unique protocol specification was decided during the year 1993 and it was successfully accepted by the ITU-R standardization body. A few other countries also tried pilot broadcasts during the year 1995. The UK has got a crown of the first country which received digital radio stations through DAB technology. Later on DAB technology was marketed for commercial purposes in the year 1999. Now it has reached almost all the heart of radio listeners by operating more than 1,000 DAB stations world wide.
Difference in technology
Technology used for DAB is entirely different from that used for FM broadcasting. FM has faced lots of issues due to ‘multi path’ interference. It is a main cause for getting disturbance in FM reception. This ‘multi path’ interference is completely eliminated in DAB technology which uses processors. These processors have come with the potential to filter out all interference. The processors have the stuff to correct even errors in signals. All the delayed signals will be combined to make high quality reception by using a receiver in DAB radios.
Advantages
You may be interested to know the name of the music album, the name of the musician and the name of the movie while you listen to a song in standard radio. It might not be possible at that time. But now you can know all these details by using DAB radio. It features a small screen and you can read even headlines in the small screens from advanced DAB stations.
An impressive advantage of DAB is ‘EPG’ which is a short form of ‘Electronic Program Guide’. Listeners can get the database of programs to be broadcasted for the coming days in advance. If you wish to record your favourite programs, you can make arrangements in advance before it is broadcasted. You can set time to record program till it ends automatically. Then you can play and enjoy whenever you like to listen them. Thanks to DAB inventors!
