摘要： The invention relates to a method of selecting a RTP (Real Time Protocol) element in a dynamic multicast tree for a multimedia conference and a record medium recorded with a program for realizing the method that can be read by computers, and in particular to a method of selecting a RTP element in a dynamic multicast tree for distributing an overload applied to the root node of the dynamic multicast tree and a record medium recorded with a program for realizing the method that can be read by computers. The method comprises the steps of: (a) confirming in the RTP element if the RTP element is subscribed to the dynamic multicast tree that a new multimedia terminal wants to join; (b) if the RTP element is not subscribed to the dynamic multicast that the new multimedia terminal wants to join according to a result of the confirmation in the step (a), joining in the RTP element the root node of the dynamic multicast tree and then causing the new multimedia terminal to join the dynamic multicast tree of a multimedia conference system; and (c) if the RTP element is subscribed to the dynamic multicast that the new multimedia terminal wants to join according to a result of the confirmation in the step (a), causing the new multimedia terminal to join the dynamic multicast tree of the multimedia conference system.
摘要翻译：本发明涉及一种选择用于多媒体会议的动态多播树中的RTP（实时协议）元素的方法，以及用用于实现可由计算机读取的方法的程序记录的记录介质，特别涉及一种方法在动态组播树中选择RTP元素以分配应用于动态组播树的根节点的过载，以及记录有用于实现可由计算机读取的方法的程序的记录介质。该方法包括以下步骤：（a）在RTP元素中确认RTP元素是否订阅新多媒体终端想要加入的动态多播树; （b）如果RTP单元根据步骤（a）中的确认结果未订阅新多媒体终端想要加入的动态多播，则将RTP元素加入到动态多播树的根节点和然后使新的多媒体终端加入多媒体会议系统的动态组播树; 以及（c）如果RTP单元根据步骤（a）中的确认结果订阅了新的多媒体终端想要加入的动态多播，则使得新的多媒体终端加入多媒体的动态多播树会议系统
