<p>A method and apparatus for transmitting digital sound are disclosed. The method contemplates transmitting a digital radio signal (such as an FM band signal) over a plurality of sub-channels (43) subject to some constraints (40) on the digital signal power. A control sub-channel (57), sometimes referred to as an auxiliary overhead channel is used to transmit control information which is interpreted by the receiver to identify the location and potentially the mode of the digital signals.</p> |
