Abstract
A dual-mode receiver that functions both as a digital audio broadcast receiver and a solid-state digital audio content player is described. In a “radio” mode, the receiver is able to: receive a digital audio bitstream, decode the received bitstream, store or render the decoded bitstream either based on an input from a user or a pre-programmed instruction from a user. In a “play” mode, the receiver is able to access the stored digital audio content, or extract stored digital audio content from a compact media device (e.g., compact flash memory) that is interfaced with the receiver.
Claims22
A digital audio broadcast receiver capable of receiving digital audio broadcast content, said receiver comprising:
- a. a perceptual audio decoder decoding said received digital audio broadcast content;
- b. an interface receiving a compact media device with stored digital audio content, said receiver extracting said stored digital audio content;
- c. one or more storage units capable of storing digital audio content comprising said decoded digital audio broadcast content and said extracted stored digital audio content, and
- d. a playlist creator operatively linked to said storage units creating a digital audio content playlist based upon said stored digital audio content.
A method for switching between a “radio” and “play” mode in a digital audio broadcast receiver, said receiver receiving, storing, and playing digital audio content, and
- when switched to said radio mode, said method comprising the steps of:
- (a) receiving a digital audio broadcast content;
- (b) decoding said digital audio broadcast content, and
- (c) storing and rendering said decoded digital audio content based upon one or more instructions from an interface, and
- when switched to a play mode, said method comprising the steps of:
- (a) extracting digital audio content from one or more storage units and a compact media device based upon one or more instructions from an interface;
- (b) decoding said extracted digital audio content, and
- (c) rendering said decoded digital audio content.
A dual mode digital broadcast receiver having a play mode and a record mode, said receiver comprising:
- a. a storage media interface for extracting storage content from a compact media device;
- b. a PAC decoder for decoding digital broadcast content and said extracted storage content;
- c. one or more storage units for storing said decoded content;
- d. a recording unit, when in record mode, triggering storage of said decoded digital broadcast content in said one or more storage units;
- e. a reproducing unit, when in play mode, rendering either said decoded digital broadcast content in said storage units or said extracted storage content;
- f. a user interface unit for receiving user commands, said user commands controlling the operation of said recording unit and said reproducing unit.
