The MP 3 jukebox can be realised as an autonomous apparatus in the wall-mountable, desk or self-supportable version, but it can also be combined with a dart-apparatus, computer based cash register, video or computer games.Its operatin is based on the utilisation of one single standard PC or notebook as a controlling, monitoring and memory unit. A combination of especially developed and astandard software packages, makes starting, usage and servicing of the apparatus, easy to a maximum extent. Complete communication between the apparatus and user is carried out ba means of keys (iiii) (1-4) and a separate OK key (5) on the front board of the apparatus. Data concerning the type of music, the performers and the titles of te songs are sorted according to the hierarchical principle "type of music-performer-title of song". The data shown on the screen have visual appearance similar to two pages of a book, so that moving from one screen to another feels like paging an pen book, in order to enable easier and quicker, both the orientation and the selection among a large amount of data. Al variants of the apparatus can be adjusted for completely autonomous usage by blind or sight-impaired persons, which is accomplished by recording the performer's name and the song title during the preparation of music , and by announcing the name of each selected performer and the song title at moving through the menu.
