Abstract
A system for use in a motor vehicle includes a wireless receiver that receives, over a wireless communication channel, supplemental information representative of the characteristics of the contents of a playback media, and provides received supplemental information indicative thereof. A playback device receives the received supplemental information and stores the received supplemental information in a non-volatile memory device. The playback unit may generate a request for supplement information in response to and indicative of a playback media inserted into the playback unit. The system may also include a wireless transmitter that receives the request and transmits the received request over the communication channel. In one embodiment, after the data medium has been inserted into the playback unit, the wireless transmitter (e.g., a car telephone) establishes a radio connection to a data server, and at least part of the characteristic data stored on the inserted data medium are read by the playback unit and are transmitted from the wireless transmitter to the data server, which compares these characteristic data with stored data to identify the data medium. After identifying the da…
