Radio preset key assignment method and apparatus

摘要

A system and method for assigning received channels to preset tuning keys of a receiver. A series of preset keys are sequentially labeled and one preset key, such as the preset key marked “0,” is a pre-defined preset key. An elongated pressing of the pre-defined key causes the currently tuned channel, if it is not assigned to a preset key, to be assigned to an unassigned preset key. If the currently tuned channel is already assigned to a preset key, pressing the pre-defined key instead causes the currently selected channel to be un-assigned from that preset key. Radios with two tuners that each process different sets of radio signals assign channels for a particular tuner to alternating preset keys, allowing acceleration of sequentially selecting channels assigned to pre-set keys by pre-tuning another tuner to the next channel in the sequence.

主权项

1. A preset key assignment apparatus for a receiver, comprising:
a channel selection processor, communicatively coupled to a plurality of preset keys, the channel selection processor adapted to assign each preset key of the plurality of preset keys to a respective channel, each preset key within the plurality of preset keys being able to cause a receiver to select a respective channel then assigned to that preset key, the channel selection processor further adapted to determine a currently selected channel of the receiver; and a preset key assigner, communicatively coupled to (i) a pre-defined preset key within the plurality of preset keys and (ii) the channel selection processor, the preset key assigner adapted to determine a pressing of the pre-defined preset key and, in response thereto, assigning the currently selected channel to an available preset key according to a defined sequence, wherein the pre-defined preset key is either:
(i) itself a preset key,or(ii) a separate key that does not function as a preset key.
