Abstract: A method for accessing content according to a location within a defined geographical area. The area is defined (104) by those areas covered by selected nodes of one or more networks. Data representing the identities of the selected nodes or of the defined geographical area is then provided (110) to authorised receivers, for example via a Smart Card or the Internet. Corresponding data is broadcast (112) to locations within the defined geographical area The receiver at such a location permits access (124) to content based on a comparison (122) of the provided and received data. The content may be stored locally on physical media or obtained remotely via a network.

Abstract: The invention comprises an information recording apparatus (1) incorporating a memory device (3) having a defined quantity of storage space, and an interface (2) for use by a user in initiating the recordal of data onto the memory device (3), wherein a selected portion of the storage space of the memory device is reserved for the recording of data in an emergency situation and the interface is configured such that instructions to record data to the selected portion of the memory device are effected by means separate from those used to initiate recordal of data in the remainder of the memory device.
