Abstract: 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.
