Abstract
A method and apparatus for synchronization control of multimedia objects in an MHEG engine are specified. The present system overcomes the shortcomings in the conventional apparatus, which is the fact that interactive processing is not allowed during presentation and that the conventional apparatus cannot control synchronized presentation for failing to provide control of the conditional, temporal, and spatial synchronization. The present apparatus has a user interface for receiving a user input during multimedia presentation whereby interactive processing can be supported, a time token processor for generating a time token event according to the times set by the time token timer, a link processor for transferring a list of action commands associated with the satisfied conditional clauses and a list of the MHEG object information to the action processor with reference to the status table and the link table upon generation of various events, an action processor for generating the action event and for creating a plurality of presentation information units to be presented for each of a plurality of channels to execute the actions received from the link processor, and a plurality of ch…
