Smartphone for interactive radio

摘要

A mobile device (31) capable of processing radio broadcast signals (36) is described. Broadcast radio signals (36) are received by said mobile device (31) and converted to desired digital audio content format (52) and then combined with output of software applications (54) running at said mobile device (31) to create a combined radio broadcast signal (55) that can be received by a automobile broadcast radio receiver (83). Said radio broadcast signal (55) is transmitted to a automobile broadcast radio receiver (83) to enable a user to interact with audio content using software applications (54) of said mobile device (31). Transmission of combined radio broadcast signal (56) is done on a different radio broadcast frequency with low power signal.
