When Paul Nipkow, who invented the Nipkow disk in 1884, saw the first time a working Nipkow disk televisor on the Berlin Funkausstellung in 1928, he went away, grim and very disappointed due to the low video quality. Of course, the camera and amplifying technology of these times did not tap the full potential of the Nipkow disk.
This here is a demonstration which shows how good mechanical television in reality can be.
In the times of HDTV, many people think that a television standard of appr. 30 lines per frame and a video bandwidth which can be distributed in telephone bandwidth, might not able to display recognizable video content.
This video demonstration should reject this opinion. As video source was selected a RCA Victor commercial from 1961 for color tv, displaying in black and white on a Nipkow disk based on the standards of 1928 and recorded in 2006. One can see that most of the video content is recognizable - even as it is displayed in 32 line format.
