Abstract
A method for dynamically sharing an application in a conference system while maintaining state regardless of whether the application is under execution in all conference devices. The conference system includes a plurality of conference devices with at least one conference device executing an application program. The method for dynamically sharing the application program among the plurality of conference devices in the conference system while maintaining state, includes the steps of: communicating a request to share the application program from a requesting conference device which is executing the application to all enrolled conference devices; storing an executed state of the application program to be shared in the requesting conference device; starting the application program to be shared by enrolled conference devices in which an application program corresponding to the application program to be shared is not started; communicating the executed state stored in the requesting conference device to all enrolled conference devices; and processing by all enrolled conference devices of the application program to be shared in a shared executed state equal to the executed state communica…
