Abstract:
1. A digital radio broadcast system for scheduling audio content and associated program data for digital radio broadcast to a digital radio broadcast receiver, comprising: a processing system; and a memory coupled to the processing system, the processing system being configured to receive first audio content, first program data, second audio content, and second program data for transmission via digital radio broadcast, the first program data identifying a first item associated with the first audio content, the second program data identifying a second item associated with the second audio content, the processing system being configured to receive the first program data and the first 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 received at the processing system, the processing system being configured to process the first audio content and the first program data for digital radio broadcast transmission via a digital radio broadcast transmitter, wherein the first program data is repeatedly delivered to the digital radio broadcast transmitter for transmission while the first audio content is being transmitted, the processing system being configured to stop delivery of the first program data to the digital radio broadcast transmitter upon receipt of the second program data, a most recent iteration of the first program data thereby being truncated so as to improve alignment between the second program data and the second audio content, and to begin delivery of the second program data to the digital radio broadcast transmitter.
