Is there power saving in simulcast mode when using one single MW transmitter?
(Ravi Saksena)
Simulcasting allows a (short) transition from analogue to digital.
The power of the transmitter is the same and the allocation of the power between analogue and digital will be decided by the broadcaster though leaving too little power for the digital component might affect reception as some of our Indian listeners know very well. Per total simulcasting does not increase power, a physical impossibility but allows for both digital and analogue, an possibly different content to be transmitted.
DRM is a purely digital standard and maintaining both modes for long can be useful (receiver acquisition, etc.) but to enjoy the full benefits of DRM, its excellent audio and data capabilities the pure digital standard as invented and ITU recommended should be used.
