    摘要： A content distribution system. A distribution management and unauthorized operation management device generates a one-time URL by using URL of content information specified by a user terminal and transmits the one-time URL and bandwidth information concerning the content information to the user terminal. A session control server extracts the one-time URL from a session control message transmitted from the user terminal, transmits it to the distribution management and unauthorized operation management device, and establishes a session between the content distribution server and the user terminal according to an authentication result performed by using the one-time URL transmitted from the distribution management and unauthorized operation management device and a correlation result obtained by correlating the bandwidth information contained in the session control message transmitted from the user terminal with the bandwidth information transmitted together with the authentication result from the distribution management and unauthorized operation management device.

    摘要： A video and audio stream is predicted that is to be selected for reception next to a video and audio stream that is being received by the terminal or that is after a video and audio stream that has been selected for reception by the terminal. Resources necessary for delivering the predicted video and audio stream, in addition to resources necessary for the video and audio stream that is being received by the terminal or that has been selected for reception by the terminal, are secured in advance before a user of the terminal selects the next video and audio stream. The predicted video and audio stream is not delivered to the terminal before it coincides with a video and audio stream that is selected at the next zapping.
