Abstract
A storing unit of a communication karaoke apparatus has a newly released music file storing area, an information file storing area, a necessary information file list storing area, and the like. Information files are used for displaying information such as concert information, and advertisements of stores and goods. The information files are displayed during an intermission of karaoke performances due to music-piece files. When a new release file is downloaded, a necessary information file list is simultaneously downloaded. Based on the necessary information file list, unnecessary information files are deleted from the information file storing area, and only necessary information files among the downloaded information files are written into the information file storing area. Accordingly, only necessary information files can be always stored.
