Abstract
A combined audio receiver and data receiver act in cooperation to serve audio presentation, digital collateral data presentation, and paging functions. The data receiver activates intermittently according to a time-division multiplexed broadcast protocol to receive paging data during brief time slots. At other times, the data receiver tunes to a frequency matching that of the audio receiver to receive digital collateral data descriptive of the audio presentation.
