Abstract: A sign of the landslide disaster is easily detected. A model learning unit (120) of an anomaly detection device (100) learns a relational expression between vibration strengths at frequencies based on a time series of frequency characteristics of a vibration strength detected during a learning period by a vibration sensor placed on a monitoring target. The anomaly detection unit (140) learns a relational expression between vibration strengths at frequencies based on a time series of frequency characteristics of a vibration strength detected during a new period by the vibration sensor. Then, the anomaly detection unit (140) determines whether or not there is an anomaly in the monitoring target based on a relational expression related to a new frequency, which is different from the relational expression learned during the learning period.

Abstract: A data recording device is provided to record and redistribute stream data such as TV programs without imposing loads proportional to the number of users. Stream data of a distributed program is collated by a recording range judging section 4 with data already recorded of a stream data recording section 6 and, based on results from the collation, only newly distributed data is appended to the stream data recording section. Recording demand information representing a range of stream data of a program that a user makes a request for recording is recorded in a range recording section 5 and a user identifier to identify the user is recorded in a manner to be associated with the above recording demand range information. Stream data only in a range corresponding to the above recording demand range information of the user recorded by the above demand range recording processing is read out by a redistributing section 7 from the stream data recording section 6 and is redistributed to the user.

Abstract: 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.

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.
