Despite whether or not Aldrin said what was quoted in the post made by TD, there was actual NASA footage (if not of the landing taking place) there was of an astronaut Armstrong taking the final steps off the lander. For proof see this video at Apollo 11 Moonwalk 20 July 1969 - restored footage - YouTube
[ https://www.youtube.com/watch?v=pJbtYs0oZfQ ] . Perhaps Aldrins memory of regarding whether or not this was television broadcast of that was faulty. In it you can see the astronaut taking his final steps off the lander. You can also see two astronauts moving around on the moon. An introduction to the video explains why the image quality is so poor.
See also Moon landing footage: Watch the historic Apollo 11 mission moments | CNN [https://www.cnn.com/videos/us/2019/07/18/apollo-11-moon-landing-scn-orig.cnn ] . It shows some footage of the spaceship approaching the moon (it looks like was recorded from within the spaceship, but maybe the camera was attached to the outside of the spaceship). Perhaps that video footage was not included in the live broadcast, but instead shown later.
Update: Thanks TD for your later post (including your clarification), namely the post in which you wrote "How we saw Aldrin's first steps ....". The article you linked to says something which gives the explanation to what had been puzzling me for some time (about why the images looked ghostly when action was taking place). It says the following. "The distance the signal needed to travel, the conversions and retransmissions required to reach televisions in homes, meant a reduction in the quality of the picture, resulting in reduced resolution and a mismatch in the signal layers. That is why sometimes the astronauts appear more like translucent ghosts than people."
