Abstract: There is described a method for providing a video signal to a user, comprising: sampling said video signal at a user specific sampling rate, thereby obtaining temporally organized sample amplitudes; removing a time interrelation between said temporally organized sample amplitudes, thereby obtaining sample amplitudes having no time interrelation; transmitting said sample amplitudes having no time interrelation to said user; and reconstructing said video signal by inserting a user-specific sampling interval between successive ones of said sample amplitudes, said user-specific sampling interval corresponding to said user-specific sampling rate.

Abstract: There is described a method for providing an audio signal to a user-end, comprising: modifying an amplitude of at least some bits of the audio signal using at least one user-specific series of bits, thereby obtaining a non-identical copy of the audio signal; transmitting the non-identical copy to the user-end; at the user-end, identifying the at least some bits within the non-identical copy; and restoring the amplitude of the at least some bits using the at least one user-specific series of bits, thereby reconstructing the audio signal.

Abstract: There is described a display device for displaying cross-sectional representations of an object, the display device comprising: a frame; and a plurality of display units mounted on the frame, each one of the plurality of display units adapted to display a cross-sectional image of the object, the cross-sectional image comprising at least one internal feature of the object and being dependent on a spatial position in a three-dimensional environment of a corresponding one of the plurality of display units on which the cross-sectional image is to be displayed, the plurality of display units being connectable to a processor adapted to generate the cross-sectional image for each one of the plurality of display units as function of the spatial position.
