This art installation by Gebhard Sengmüller, in collaboration with Franz Büchinger and supported by Fels-Multiprint takes the basic principle of transmiting moving images and opens up, making the whole concept clearer:

From the YouTube description:
“A Parallel Image is an electronic camera obscura. This media-archaeological, interactive sculpture is based on the fictive assumption that the currently still valid principle of electronically transmitting moving images, namely by breaking them down into single images and image lines, was never discovered. The result is an apparatus that attempts a highly elaborate parallel transmission of every single pixel from sender to receiver. This is only possible by connecting camera and monitor using about 2,500 cables. Unlike conventional electronic image transmission procedures, A Parallel Image is technologically completely transparent, conveying to the viewer a correspondence between real world and transmission that can be sensually experienced”.
