Краткое описание:
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Astra Digital Radio (ADR) is a system used by SES Astra for digital radio transmissions on their Astra 1 satellites, using the audio subcarrier frequencies of analogue television channels. It was introduced in 1995. As of February 2008, there are still 51 stations transmitting in this format. The format uses one mono audio subcarrier, which would normally be allocated to an additional sound track or radio station, or half of a stereo sound track/station. The carrier is digitally modulated, and carries a 192 kbit/s, 48 kHz sampled MPEG-1 Layer II (MP2) encoded signal. 9.6 kbit/s is available for data. Special receivers are required to listen to ADR stations, although some combined analogue/digital satellite boxes as well as later normal analogue boxes are equipped to decode it.
