  RF signal transmitted is first demodulated and then using FDM process gets converted into the required form you need

  when someone talks to you information travels towards you in the form of a sound wave.your ears and brain decodes this information making you understand it.this is what happens when you listen to a audio or sees a video on Tv.information travels to an elcetronic device in the form of a cable signal , satellite signal or radio waves.the device decodes and displays the signal.
  in streaming video and audio, the traveling information is a stream of data from a server. The decoder is a stand-alone player or a plugin that works as part of a Web browser. The server, information stream and decoder work together to let people watch live or prerecorded broadcasts.
