A method for transmitting alternative image content of a physical display to different viewers, comprising: generating at least two different sets of image data, each set of image data comprising a sequence of individual images, wherein at least one set of image data comprises a sequence of images and inverse images, wherein the inverse image of each preceding and/or subsequent image is generated such that the combined image and inverse image result in a perceived image having a homogenous intensity; displaying the images of said at least two sets of image data in a time-sliced multiplexed manner at a high frame rate on said physical display; generating at least two video streams of a scene which includes said physical display, said video streams consisting of video frames captured synchronously with the displaying of the images of two of said at least two sets of image data on said physical display which are transmitted to at least two video outputs at a standard frame rate, said video outputs being physical video outputs of an intermediate processing unit; and transmitting said at least two video streams to different sub-sets of said viewers, wherein said at least two video streams of said scene which includes said physical display are generated by: recording a high frame rate video signal of said scene with a camera unit at a high frame rate, said high frame rate being an integral multiple of a standard frame rate, transmitting said high frame rate video signal from said camera unit to said intermediate processing unit comprising at least one connect unit having an input for said high frame rate video signal and plurality of said physical video outputs, wherein the number of said video outputs is greater than or equal to said integral multiple, said intermediate processing unit being a baseband process unit arranged between said camera unit and a camera control unit; converting said high frame rate video signal into standard frame rate video signals by cyclically transmitting consecutive frames of said high frame rate video signal to consecutive video outputs of said number of video outputs such that each frame of said high frame rate video signal within a time period corresponding to the standard frame rate is transmitted to the same physical video output; obtaining said at least two video streams at a standard frame rate at least two of said integral number of video outputs. generating at least two different sets of image data, each set of image data comprising a sequence of individual images, wherein at least one set of image data comprises a sequence of images and inverse images, wherein the inverse image of each preceding and/or subsequent image is generated such that the combined image and inverse image result in a perceived image having a homogenous intensity; displaying the images of said at least two sets of image data in a time-sliced multiplexed manner at a high frame rate on said physical display; generating at least two video streams of a scene which includes said physical display, said video streams consisting of video frames captured synchronously with the displaying of the images of two of said at least two sets of image data on said physical display which are transmitted to at least two video outputs at a standard frame rate, said video outputs being physical video outputs of an intermediate processing unit; and transmitting said at least two video streams to different sub-sets of said viewers, recording a high frame rate video signal of said scene with a camera unit at a high frame rate, said high frame rate being an integral multiple of a standard frame rate, transmitting said high frame rate video signal from said camera unit to said intermediate processing unit comprising at least one connect unit having an input for said high frame rate video signal and plurality of said physical video outputs, wherein the number of said video outputs is greater than or equal to said integral multiple, said intermediate processing unit being a baseband process unit arranged between said camera unit and a camera control unit; converting said high frame rate video signal into standard frame rate video signals by cyclically transmitting consecutive frames of said high frame rate video signal to consecutive video outputs of said number of video outputs such that each frame of said high frame rate video signal within a time period corresponding to the standard frame rate is transmitted to the same physical video output; obtaining said at least two video streams at a standard frame rate at least two of said integral number of video outputs.
