User specific resampling for access protection of digital content

摘要

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.
