It was only a matter of time before the media industry began pondering the satellite’s potential in television. Just like traditional broadcasting antennas, satellite television works with radio waves as well but with a much broader range. If the the larger dishes transmitted analog signals, then the smaller dishes send digital signals. Compare to older dishes which rarely required decoding, smaller dishes produce a higher quality of sound and video. Digital signal is encoded into MPEG-2 format, just like the format used in DVD’s. It will then transmitted to your receiver box where it is decoded and translated into an analog signal that is then fed to your television. Digital produces enhanced video and audio that you just can’t get from analog. It never stops there yet. So, in order to receive satellite programming, you will need broadcast satellite providers.
