The output of the video camera is fed into the VCR and from there the signal goes to the input of the TV. That is a feedback circle because the camera's signal is fed into the TV. The VCR takes a sequence of 25 pictures/frames a second. When you have recorded the signal from the camera for 5 minutes you will have 5 x 60 sec x 25 frames/sec = 7500 frames. In the replay mode Schreiber used the still mode function to look at each single frame hoping to see something unexpected. This technique allowed pictures from beyond to be observed for the first time. |

Instead of using a VCR one can use today a computer with the right graphic card (video in and video out), high storage capacity of the hard disk and software in order to have a look at each single frame. That is of course an easier job for the computer. The VCR can be damaged mechanically while observing thousands of individual frames.
