Abstract
A device (100) for receiving, storing and playing back digital audio radio signals comprises a receiver (203), a decoder (502 and/or 504), a user input (516), a storage medium (510) coupled to the decoder, and a system controller (508) coupled to the user input. The receiver receives a digitally encoded bit stream (300) on a plurality of communication resources (104), wherein each communication resource contains content and associated index information. The decoder selectively decodes a selected plurality of communication resources and the user input selects the selected plurality based on the associated index information and selects a portion of the content contained in selected plurality to be retrieved. The storage medium stores the content and associated index information contained in the selected plurality of communication resources and the system controller stores and retrieves content to and from the storage medium based on input received at the user input.
