Method to block audio and data in a digital radio receiver

摘要

Locking out of an audio broadcast station at a target channel frequency is provided by using a block-out table containing undesirable program content as determined by an authorized user, wherein the authorized user constructs the block-out table containing an identifying data of the audio broadcast station and a microcontroller compares the identifying data of the audio broadcast station with an identifying data of an audio signal to determine if the program content should be blocked out or reproduced for a listener.
