Abstract
In digital radio technology, information channels describing the properties of the associated performance channel(s) are included in the broadcast band. The digital radio determines when selected signal groups are present in the information channels. Upon identification of a selected signal group, the digital radio automatically reconfigures itself into a user-determined configuration for processing the performance channel. By way of specific example, the user can determine that the equalization of the performance channel for selected musical formats and/or selected artists.
Claims14
A digital radio, the digital radio receiving broadcast bands including at least one information channel and at least one performance channel, the digital radio comprising;
- a processor processing all performance channels, the processor having a selectable mode monitoring at least one information channel the broadcast band selected by the receiver;
- and
- a memory unit exchanging signals with the processor, the memory unit including at least one software program for configuring the processor to process performance channels in a selected mode of operation;
- wherein when the processor selectable mode identifies a preselected signal set in the information channel, the processor accesses a software program, the processor in response to the software program processes the performance channels in a manner determined by the software program.
A method for enhancing the reproduction of a performance item by a digital radio, the method comprising:
- monitoring a demodulated and decoded information channel for selected signal groups;
- and
- when a preselected signal group is identified, reconfiguring the digital radio in a user-determined manner;
- wherein reconfiguring the digital radio results in a predetermined processing of a demodulated and decoded performance channel by the digital radio.
A system for transmitting a performance item for reproduction, the system comprising:
- a broadcast band transmitting unit, the broadcast band transmitting unit transmitting a broadcast band including performance item in a performance channel and signal groups in an information channel identifying properties of the performance items, the transmitting unit including at least one digitally-encoded channel;
- and
- a digital radio for demodulating and decoding the broadcast band channels, the digital radio having a plurality of configurations for the performance channel, the digital radio assuming one of the pluralities of configurations in response to a selected signal group in the information channel.
