Qué (quién) es Astra Digital Radio - definición
DIGITAL RADIO TRANSMISSION SYSTEM
Astra Digital Radio
<audio> Digital Radio over satellite, compatible with analog
television transmissions. Alternatively the normal TV
subcarriers can be modulated by a MPEG-1 Layer-2 48 kHz 192
kbps signal. Quality is better than analog carriers and only
needs half the bandwidth (analog stereo = 2 carrier, digital
stereo = 1 carrier). Quality is limited and the data rate
can't be increased.
