NASA has released newly restored video of the Apollo 11 Moon landing to celebrate the 40th anniversary of this feat.
The inclusion of a TV camera for the moon walk was a last second decision. The camera was thrown together out of spare parts (including a Barlow lens for an astronomical telescope from Edmund Scientific). As a result, the ground-based support for video was less than prepared to handle rebroadcasting of the images in all the world's TV standards.
The original broadcasts (including the one seen in the US) were handled by simply pointing a TV camera in the correct video standard at a long persistence phosphor monitor showing the feed from the Moon. Further complicating matters was that the decision by Armstrong to skip the sleep period and do the moon walk early, which meant that instead of using the dish at Goldstone, which had planned to handle the video feed, the moon walk images were relayed through the dish at Parkes, Australia.
Because of the last second shuffle, the first generation tapes of the moon feed were not preserved at NASA, but fortunately, Parkes had made an extra set which were found in an archive in Australia.
As a side note, the above version appears to have an incorrect aspect ratio. The original TV camera on Apollo was a standard 4x3 aspect and this looks stretched to fit an HD 16x9.
