Abstract:With the rapid development of the global automotive industry, vehicle-mounted multimedia has become a necessary equipment for people to drive and entertain. The traditional FM and AM broadcasting radio functions have been affected by the sound quality due to the restrictions on the direction of receiving signals and the transmission distance. The use of satellite broadcasting can improve sound quality while also providing more radio channels and functions. Sirius XM's Sirius XM satellite broadcasting service replaces traditional FM and AM radio services to improve the quality and user experience of vehicle-mounted systems. In this paper, SiriusXM satellite broadcasting service is used to design audio playback software with multimedia on board.
