1. A method for recording at least one of video data and audio data generated by a capturing device having an associated data memory, comprising:
- connecting, via a digital network, the data memory of the capturing device to at least one recording device that has a greater storage capacity than the data memory of the capturing device, wherein the at least one recording device is physically remote from the capturing device;
exchanging data between the data memory of the capturing device and the at least one recording device, whereby a virtual data memory is formed for access by the capturing device by operational connection between the data memory of the capturing device and the at least one recording device, the virtual data memory representing a combined data memory capacity formed by the data memory of the capturing device and the at least one recording device;
at the capturing device, receiving a request from a user to access the exchanged data, wherein the request does not differentiate between data stored on the data memory of the capturing device and data stored on the virtual data memory; and
responsive to the request, retrieving the exchanged data stored on the virtual data memory, the retrieving occurring at the capturing device.

28. A data capturing device for at least one of video and audio data, comprising:
-
a data memory for storing at least one of video and audio data; a control device for the data memory; and an interface unit for facilitating communication via a digital network with at least one central recording device which is physically remote from the data capturing device, wherein data are transmitted via the interface unit and the digital network to the at least one central recording device; wherein reading-out of data from the data memory for transmission to the at least one central recording device is operationally dependent on input of new data into the data memory, and whereby a virtual data memory is formed for access by the capturing device by operational connection between the data memory and the at least one central recording device via the digital network, the virtual data memory representing a combined data memory capacity formed by the data memory of the capturing device and the at least one central recording device, the interface unit being configured to retrieve the transmitted data from the at least one central recording device in response to a request from a user to access the transmitted data, wherein the request does not differentiate between data stored on the data memory and data stored on the at least one central recording device. - View Dependent Claims (29, 30, 31, 32, 33, 34, 35)

36. A recording system for capturing and storing at least one of video and audio data, comprising:
-
at least one central recording device; and a data capturing device located physically remote from the at least one central recording device, the data capturing device including; a data memory for storing at least one of video and audio data; a control device for the data memory; and an interface unit for facilitating communication with at the least one central recording device via a digital network, wherein data are transmitted via the interface unit and the digital network to the at least one central recording device; wherein reading-out of data from the data memory of the data capturing device for transmission to the at least one central recording device is operationally dependent on input of new data into the data memory of the data capturing device, and whereby a virtual data memory is formed for access by the capturing device by operational connection between the data memory and the at least one central recording device via the digital network, the virtual data memory representing a combined data memory capacity formed by the data memory of the data capturing device and the at least one central recording device; wherein, if the data from the data memory of the data capturing device have been transmitted to the at least one central recording device intact, the at least one central recording device sends a notification of the intactness of the transmitted data to the data capturing device, and wherein, upon receipt of the notification of the intactness of the transmitted data, the data capturing device deletes the transmitted data from the data memory, the interface unit being configured to retrieve the transmitted data from the at least one central recording device in response to a request from a user to access the transmitted data, wherein the request does not differentiate between data stored on the data memory and data stored on the at least one central recording device.
