A New Multimedia Synchronization Specification Method for Temporal and Spatial Events

T h i s paper proposes a n e w mul t imed ia synchronizat i o n specification method, called SSTS (Synchronizat i o n Specif ication method f o r Temporal and Spat ial events) t ha t can specify spatial even t s a s wel l a s t emporal even t s synchronizat ions between mult iple med ia obj ec t s in a single f ramework . In th i s proposed me thod , a temporal and spatial events of a med ia object are specified as nodes, and the i r temporal relations are specified as edges, in a synchronizat ion specification graph. T h i s approach helps t o easily specify t he temporal relat ion tha t one temporal o r spatial event tr iggers o ther temporal o r spatial events wi thout breaking t h e med ia object i n t o several independent med ia objects. This pap e r also presen t s a prototype authoring s y s t e m based o n SSTS wi th S c r i p t X u n d e r W i n d o w s 9 5 t o show t h e usefulness of proposed specification method.
