    摘要: A video distribution system according to the present invention includes a user terminal, an SIP session controller, and a video distribution server. When the SIP session controller receives a request to establish a session, the SIP session controller establishes a session between the user terminal and the video distribution server, and controls a bandwidth controller to reserve a bandwidth for the distribution of video content in a communication path between the user terminal and the video distribution server. The video distribution server sends a bandwidth changing request for requesting the SIP session controller to change the bandwidth to reserve a bandwidth depending on a fraction of the bandwidth that is needed for distributing video content. In response to the bandwidth changing request, the SIP session controller further secures a bandwidth for the distribution of video content in the communication path between the user terminal and the video distribution server.
