Satellite Radio Technology



Satellite radio technology is equivalent to cable or satellite television, and it is definitely here to stay. There are several reasons for this: the quality of transmission is higher, the quality of the reception device is larger and more general coverage of channels, namely the so-called satellite footprint is far greater, and

This has the consequence that, if you travel a great distance, you will be able to stay with the same channel without having to seek new every forty or fifty miles as you have to do with AM or FM radio stations.

How to get to this quality, recording and playback speed should be around 384 kbps razini.Pjesme are cataloged in a comparable way to the MP3 system, which uses names called ID3 tags.

Each station on satellite radio is trying to create your own music identitet.Postaja can try to only one type of music or just one era or decade. This means that you May get a satellite radio station called 1970 Punk music or the twentieth century classical music.

On some channels, music controller or disk jockey will choose, say, fifty minutes worth of music, will listen to it in order to determine the quality and how to correct and then let the computer to play a more odairwaves. This allows for ten minutes every hour for the news and then the sequence can be repeated automatically.

Satellite transmission uses digital images, and each cell is transmitted at different frequencies. Similarly, each decoder, for example, in your car or your home to identify and decode each channel separately too. This coding and decoding is done very quickly, in fact, in what is called 'real time'.

a result of a binary or digital code is then translated into analog signals so that the speakers you can turn it on again. This process creates a sound that is just about CD quality.

transfer of satellites in geo-static orbit 23,000 miles above the equator and have a large footprint that is the name for the area of ​​soil that is able to receive their broadcasts.

in America, for example, two areas are concentrated at the beginning of the densely populated east and west coasts in order to maximize potential revenue. One satellite will be unable to cover the whole of the United States in that orbit.

In order to receive satellite transmissions, you will need to use a special antenna to the decoder. This antenna must be able to receive L-band emissions for it to be useful.

These new antennas are a huge improvement on the parabolic dishes (similar to those used for satellite television) that one used to have in order to take advantage of satellite radio technology.
