An object-oriented model for spatio-temporal synchronization of multimedia information

Proposes an extension to an earlier proposed temporal synchronization model, called OCPN. The new model allows one to specify spatial operations at the time of authoring the multimedia information. The authors present a mechanism to translate the model into an object-oriented environment. For this purpose the temporal operations are selected as objects. This scheme has many advantages over the existing object-oriented model since it requires fewer number of objects as well as do not limit the users to share the actual raw data. A polynomial time algorithm is proposed to translate the new OCPN into an object hierarchy
