摘要

多媒体对象之间的时间关系是不可避免的。因此，及时同步多个数据流已被认为是多媒体应用的一个关键要求。研究了分布式多媒体对象之间的同步需求。我们描述了一个处理实时媒体对象的流间和流内同步需求的时态模型。提出了阻塞策略和受限阻塞策略。此外，该模型还处理了模糊场景远程编排中可能存在的精确和不确定的时间需求。包含不精确同步约束的模糊场景(例如未知的对象表示起始点或结束点)可以转换为更精确的时间规范。本文提供了几个例子来说明我们的方法。

MediaWare: on multimedia synchronization

Temporal relationships are inevitable among multimedia objects. Synchronization of multiple data streams in time has thus been recognized as a crucial requirement for multimedia applications. We study the synchronization requirements among distributed multimedia objects. We describe a temporal model that deals with interstream and intrastream synchronization requirements in live media objects. Both the blocking policy and the restricted blocking policy are presented. In addition, our model handles the accurate and uncertain temporal requirements which may exist in the teleorchestration of fuzzy scenarios. The fuzzy scenarios that contain imprecise synchronization constraints, such as unknown object presentation starting or ending points, can be transformed into more accurate temporal specifications. The paper provides several examples to show our approach.
