Digital Radio via Satellite (DSat):
For home listening digital radio via satellite is a far better option than DAB. The reason for this is that the bit rates are either higher or the same on satellite as they are on DAB and the equipment doesn't cost very much.
The BBC stations; on DAB for the majority of the day Radios 1-4 are transmitted at 128, 128, 192, and 128kbps respectively.
The same stations on satellite are all 192kbps.
The streams over both DAB or DSat are both encoded in MP2 format so the DSat streams are of higher quality. There are no problems due to audio processing or vinyl screwing up the audio quality because the encoders don't run out of bits.
The reason why the bit rates are higher on satellite than on DAB is that on satellite the bandwidth available is far higher in the satellite band in comparison with the VHF band which is where DAB presently transmits.
There is nothing inherently wrong with DAB it just lacks enough bandwidth for the stations to properly exploit the system by using the higher bit rates.
