key media
Examples
- In this thesis , the complicated temporal relationship and dynamic synchronization properties existed in multimedia in distributed multimedia system , and the problem of higher priority demands of key medium in application , and etc . are studied thoroughly ; the course of multimedia communication , the transmission characteristics and the synchronization requirements of multimedia objects , and the algorithms of channel allocation and synchronization transmission schedule in synchronization communication scheme , and etc . are studied deeply ; at the same time , the problems of multimedia synchronization control mechanism in the practical packet - switching networks and so on are studied too
本文深入研究了分布式多媒体系统中，多媒体具有的复杂的时态关系和动态同步特性，以及关键媒体在应用中享有同步优先权等问题；深入研究了多媒体通信过程和多媒体对象的传输特性、同步需求，以及同步通信方案中信道分配以及同步传输调度算法等问题；同时，深入研究了实际分组交换网络中多媒体同步控制机制等问题。 - An improved interactive dynamic multimedia synchronization model ( idsm ) based on tpn is proposed . the new model takes the dynamic synchronization properties and the demands of the priority of key medium and the function of user interaction in the distributed systems into account , introduces the allowed blocking time , backtracking rules and so on to handle the problems caused by random delay , blocking or lost packets , and describes the temporal behavior of multimedia information stream fully , accurately and formally . 4
提出了一个新的基于tpn网的交互式多媒体动态同步模型idsm ，该模型充分考虑到分布式环境中多媒体的动态同步特性以及关键媒体的优先权和人机交互要求，通过引入容许阻塞时间、回溯算法等有效克服了网络随机延迟、阻塞和丢包等因素的影响，以形式化的方式完整、准确地描述了多媒体信息流的时间行为。
