ABSTRACT:
A reproducing apparatus has means for reproducing for a user images and audio items stored on a record carrier (compact disc). The apparatus is controlled by a simple microcontroller running a predetermined program. To enable items to be presented to the user in a reproduction sequence with user-selected branching, the desired reproduction sequence is broken into selection points and linear reproduction sequences. A selection item is stored on the disc for each selection point, while a sequence item is stored for each linear reproduction sequence, these sequence and selection items containing further item references to link them into the described composite reproduction sequence. The logic and storage requirements imposed on the microcontroller are minimal.
