SimulcastA simulcast takes place when a program or event is simultaneously broadcast across more than one broadcast platform at the same time. For example, Virgin Radio is simulcast on both AM and on satellite radio; the BBC's Prom concerts are often simulcast on both BBC Radio 3 and BBC Television. Simulcasts via satellite can be a challenge, as there is a significant delay because of the distance (nearly 50,000 miles or 80,000 km round-trip) involved. Anything involving video compression (and to some extent audio data compression) also has an additional significant delay, which is noticeable when watching local TV stations on direct broadcast satellites. Even though the process is not instantaneous, this is still considered a simulcast because it is not intentionally stored anywhere. Multiplexing (also sometimes called "multicasting") is something of a reversal of this situation, where multiple program streams are combined into a single broadcast. The two terms are sometimes confused. In horse racing, a simulcast is a broadcast of a horse race which allows wagering at two or more sites; the simulcast often involves the transmission of wagering information to a central site, so that all bettors may bet in the same betting pool, as well as the broadcast of the race. As Simulcast one calls also the simultaneous transmission of a similar amplitude-modulated and one after that digitally radio Mondiale - procedures of transferred signal in the same channel. For this the DRM signal the carrier is modulated in the procedure of the quadrature modulation and modulated on this signal then the similar signal, whereby depending upon for the order of standing range conventional amplitude modulation or To compatible single-sideband modulation can be used. The Simulcast procedure has the advantage in relation to the pure DRM procedures that also from old To receivers will receive the signal can. However this procedure has the disadvantage of a worse transmission quality in relation to the pure DRM procedures, and also with the receipt with conventional To radios it can come to a stronger noise than with the receipt of a pure To transmitter. - http://www.drm.org/newsevents/faqs/faq-053.htm
