Astra Digital Radio (ADR) was a system used by SES for digital radio transmissions on the early Astra satellites, using the audio subcarrier frequencies of analogue television channels. It was introduced in 1995. As of February 2008, there were still 51 stations transmitting in this format. ADR ceased on 30 April 2012 when analogue broadcasts on Astra 19.2°E ended.

Details

The format used one mono audio subcarrier, which was normally allocated to an additional audio track or radio station, or one channel of a stereo audio track/station. The carrier was digitally modulated and carried a 192 kbit/s, 48 kHz sampled MPEG-1 Layer II (MP2) encoded signal. 9.6 kbit/s was available for data.

Special receivers were required to listen to ADR stations, although some combined analogue/digital satellite boxes and later standard analogue boxes were equipped to decode it.

ADR was succeeded by DVB-S, with which it is incompatible, despite both being transmitted using MP2 and generally at the same bitrates. As a result, when the final analogue switch-off on the Astra 1 satellites occurred, ADR became obsolete.

The majority of the channels to have been broadcast using ADR were in the German language.[ citation needed ] In some ways,[ which? ] the system is seen[ by whom? ] to have replaced the Digitales Satellitenradio system, dating from the 1980s, which used an entire satellite transponder to carry 16 NICAM [1] encoded radio stations, and which closed in 1999.

A subcarrier is a sideband of a radio frequency carrier wave, which is modulated to send additional information. Examples include the provision of colour in a black and white television system or the provision of stereo in a monophonic radio broadcast. There is no physical difference between a carrier and a subcarrier; the "sub" implies that it has been derived from a carrier, which has been amplitude modulated by a steady signal and has a constant frequency relation to it.

A radio orchestra is an orchestra employed by a radio network in order to provide programming as well as sometimes perform incidental or theme music for various shows on the network. In the heyday of radio such orchestras were numerous, performing classical, popular, light music and jazz. However, in recent decades, broadcast orchestras have become increasingly rare. Those that still exist perform mainly classical and contemporary orchestral music, though broadcast light music orchestras, jazz orchestras and big bands are still employed by some radio stations in Europe.

History of television in Germany aspect of history

The first regular electronic television service in Germany began in Berlin on March 22, 1935, as Deutscher Fernseh Rundfunk. Broadcasting from the Fernsehsender Paul Nipkow, it used a 180-line system, and was on air for 90 minutes, three times a week. Very few receivers were ever privately owned, and viewers went instead to Fernsehstuben. During the 1936 Summer Olympics, broadcasts, up to eight hours a day, took place in Berlin and Hamburg. The Nazis intended to use television as a medium for their propaganda once the number of television sets was increased, but television was able initially to reach only a small number of viewers, in contrast to radio. Despite many technical improvements to camera technology, allowing for higher resolution imaging, by 1939, and the start of World War II, plans for an expansion of television programming were soon changed in favor of radio. The production of the TV receiver E1, that had just started was cancelled because of the war. Nevertheless, the Berlin station, along with one in occupied Paris, remained on the air for most of World War II. A special magazine called Fernsehen und Tonfilm was published.
