Rotary control for quick playlist navigation in a vehicular multimedia player

摘要

A multimedia player having a limited user interface achieves quick and easy navigation within a large playlist of stored digital audio files by employing the rotary volume control knob in a separate mode to advance or rollback sequentially through the playlist. Thus, an MP3 player can be implemented for an automotive or vehicular multimedia player without increasing the number of user control elements, such as buttons, knobs, or other switches.
