摘要： A security device and system is disclosed. This security device is particularly useful in a security system where there are many security cameras to be monitored. This device automatically highlights to a user a camera feed in which an incident is occurring. This assists a user in identifying incidents and to make an appropriate decision regarding whether or not to intervene. This highlighting is performed by a trigger signal generated in accordance with a comparison between a sequence of representations of sensory data and other corresponding sequences of representations of sensory data.

摘要： An information handling method in which information items are mapped to respective nodes in an array of nodes by mutual similarity of the information items, such that similar information items map to nodes at similar positions in the array of nodes; a mapping relationship being defined between feature data relating to an information item and nodes in the array of nodes comprises the steps of: (a) for each of a group of information items: detecting feature data representing each of a set of properties of that information item; (b) for the ensemble of feature data corresponding to the group of information items: detecting more significant and less significant properties within the ensemble; discarding feature data relating to less significant properties, the remaining non-discarded feature data being associated so as to generate a reduced feature vector for each information item; (c) defining a mapping between the reduced feature vectors and nodes in the array of nodes.

摘要： An application programmer's interface provides a facility for accessing metadata describing the content or attributes of information material. The application programmer's interface comprises a signalling protocol processor operable to receive a metadata string which includes a resource identifier providing an address of a metadata resource, and a file transfer processor operable to provide access to the metadata resource in accordance with a request from the application program. The signalling protocol processor provides an efficient facility for communicating the metadata string. The metadata string may be in the form of a mark-up language such as XML. The metadata resource may be for example a proxy version of the information material, such as a video proxy if the information material is video. Accordingly, the file transfer processor is arranged to provide efficient access to the video proxy using the address provided with metadata string. The address may be a Uniform Resource Identifier address allowing access to the resource from any network linked via the World Wide Web. The application programmer's interface therefore provides a standard interface format for making metadata and metadata resources available to application programs.
