Re: Receivers Introduced at pre-IBC Event to be Seen at RAI on Sep 10th, DRM.

Digital broadcasting in all forms is still trying to claw its way to being something useful, after years, decades of introduction. People have been more willing to go on to something new to listen to audio, rather than to ask for AM and FM to be remade digitally, and analog AM and FM have remained popular.

I think the biggest problem with digital radio, if it takes over and becomes the standard, is that broadcasters are under pressure to constantly add more stations and they will cut up any bandwidth into the smallest streams they can get away with, leading to low audio quality for all.

You can experiment with DRM right now, using transmitter hardware with an I/Q input, and a computer with DRM generator software. The software takes in program audio and generates a DRM signal that is output from the left and right channels of the computer's sound card to the I and Q inputs of the transmitter. It's like an SDR receiver, only in reverse. An SDR can receive the signal.
