Abstract (en)
[origin: WO0176240A1] Method and apparatus for processing an input video signal (Figure 2a) with protection against unauthorized reproduction thereof by means of substantial smoothing, around raster transitions of the input video signal and during a smoothing period (TEO) of variable duration, of the input video signal so as to provide an output video signal (Figure 2c) which is suitable for display thereof by a display apparatus (10), but whose smoothed segments after registration and reproduction by a registration apparatus (11) will, when displayed by the display apparatus (10), lead to incorrect raster synchronization.
