Two engineers of Bell Telephone Laboratories carry on a conversation using the experimental Picturephone system they helped develop. L. H. Meacham is using the hands-free Picturephone while watching A. D. Hall, who is using the handset for the call.

The Picturephone is connected to the switching station by three pairs of wires -- one for transmitting and receiving the audio signals, one for transmitting video signals, and the third for receiving video signals.
