other Embodiment approach

[0208] Other embodiments comprise a computer program for performing any of the methods described herein, stored on a machine readable carrier.

[0209] So, in other words, one embodiment of the inventive method is a computer program with program code for carrying out any of the methods described herein, when the computer program is run on a computer.

[0210] Therefore, another embodiment of the methods of the present invention is a data carrier (or digital storage medium or computer readable medium) having recorded thereon a computer program for performing any of the methods described herein.

[0211] Thus, another embodiment of the inventive method is a data stream or a series of signals representing a computer program for performing any of the methods described herein. The data stream or series of signals may, for example, be configured for transmission via a data communications link (eg, via the Internet).

[0212] Another embodiment includes processing means (eg, a compu...
