STRPN－多媒體時空關係展示延伸型Petri Net模式
STRPN-A Petri Net Extending Model for Scripting Spatial-Temporal Relations between Multimedia Objects
摘要
多媒體的展示涉及媒體之間展示時序與空間配置的問題，而這些時空關係語意往往是相當抽象的。為了描述多媒體展示時的時空關係語意，歷年來已有許多模式相繼提出，這些既有模式或偏重於時間關係描繪，或僅提供空間關係敘述，缺乏完整描繪時空關係，尤其是移動物件間之相對時空關係語意描繪的機制。本研究提出一套圖形化且能完整描述多媒體展示的時空關係模式，尤其是能描繪動態、靜態物件間即時性之相對時空關係語意。運用本模式，多媒體系統分析或設計人員，可用一種常規的形式，清楚地描述出多媒體展示時各媒體物件間的時間同步與空間組成關係，並可作為與其他終端用戶溝通展示內容的橋樑與工具。

Inevitably multimedia systems are involved with temporal and spatial coordination, which are not so easy to describe exactly due to their abstract semantic meanings. Coordination of spatial or temporal relations between objects has been investigated recently; however, none have focused on the correlation of both dimensions, especially in describing moving objects. A formal model with graphical scripting tool is proposed in this paper. The model describes the spatial and temporal correlative semantic for moving and stationary objects. Multimedia system designers and analyst can describe multimedia presentations with the model.
