Current multimedia applications assume that the human user can exploit visual information originating from semantically independent sources. This motivates the design of devices providing picture-in-picture information, navigation interfaces, which are known as electronic program guides in the television domain, etc. The use of audio information in such multimedia applications is constrained to making available the audio signal of the main presentation or the audio signal of the currently selected item in a navigation interface. According to the invention a plurality of corresponding audio signals is reproduced, wherein said reproduced audio signals correspond to those multimedia presentations that are currently in the focus of attention of a navigation control device or a user. <IMAGE> |
