Method and apparatus for digital audio playback using local stored content
First Claim
1. A device for receiving, storing and playing back digital audio radio signals, comprising:
- a receiver for receiving a digitally encoded bit stream over-the-air on a plurality of communication resources, wherein each of the plurality of communication resources contains content and associated index information;
a decoder for selectively decoding a selected plurality of communication resources;
a user input for selecting the selected plurality of communication resources based on the associated index information and for selecting a portion of the content contained in selected plurality of communication resources to be retrieved;
a storage medium coupled to the decoder for storing the content and associated index information contained in the selected plurality of communication resources;
a system controller coupled to the user input for storing and retrieving content to and from the storage medium based on input received at the user input.

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.
