Abstract
A digital radio broadcast system includes a processing system that receives first audio content, first program data identifying a first item for the first audio content, second audio content, and second program data identifying a second item for the second audio content such that a start of the first program data is received at the processing system within 0.5 seconds of a start of the first audio content. A digital radio broadcast signal including the audio content and the program data is processed for digital radio broadcast transmission via a transmitter. The processing system stops delivery of the first program data to the transmitter upon receipt of the second program data, the first program data thereby being truncated, and begins delivery of the second program data to the transmitter. A digital radio broadcast receiver can tag content of interest based on a user command registered at the receiver.
