发明名称 Content delivery server and terminal apparatus
摘要 During the reception of a content delivery service, if the service is continued by switching a communication path, a temporary interruption occurs upon the switching of a session. There are cases where the same service cannot be continued if the communication speed of the communication path prior to switching is greatly different from that of a communication path after switching. Sessions for delivering two contents each encoded from the same source data, having different bit rates, and temporally synchronized with each other are established simultaneously with respect to a client terminal. The sessions are switched at the client terminal based on information on the respective times of content data from the two sessions such that a temporal continuation is provided therebetween.
