Simulcast

Simulcast is a contraction of "simultaneous broadcast", and refers to programs or events broadcast across more than one medium, or more than one service on the same medium, at the same time. For example, Virgin Radio is simulcast on both AM and on satellite radio, and the BBC's Prom concerts are often simulcast on both BBC Radio 3 and BBC Television. Another application is the transmission of the original-language soundtrack of movies or TV series over radio, with the television broadcast having been dubbed into a local language.
