Abstract

The invention relates to a playback control unit which is connected with a playback device for CDs or records, wherein these provide coded information by means of which the playback device can be controlled. In this way, in addition to the playback speed, further functions can be controlled, namely selecting elements from a list, in particular a music archive, or determining skip marks or controlling software modules or the length of audio loops or a continuous modification of parameters, in particular audio effect parameters, for volume, filter, flange, echo, delay or a playback control of video sequences or parameters of video sequences, in particular colour, resolution or parameters and positioning of objects in computer games.
