Abstract
A head unit outputs a control bus command in response to an input operation by a user. A conversion unit converts the control bus command into a USB data frame and outputs the USB data frame to a notebook personal computer. Based on the USB data frame, and notebook personal computer reads music data stored in a hard disk drive, and outputs the music data to the head unit via the conversion unit. If the music data is compressed, the music data is decoded at the notebook personal computer. Thus, a dedicated decoding LSI need not be provided in the head unit.
