This live conversion was crude compared to early-21st-century electronic digital conversion techniques. Image degradation was unavoidable with this system as the monitor and camera's optical limitations significantly lowered the original SSTV signal's contrast, brightness and resolution. If the scan converter's settings were incorrectly set, as they were at the Goldstone station during the first few minutes of Apollo 11's moonwalk, the negative impact on the image could be very obvious. When Armstrong first came down the Lunar Module's ladder, he was barely visible because the contrast and the vertical phase were not set correctly by the scan converter operator. The video seen on home television sets was further degraded by the very long and noisy analog transmission path. The converted signal was sent by satellite from the three receiving ground stations to Houston. Then the network pool feed was sent by microwave relay to New York, where it was broadcast live to the United States and the world. Because all of these links were analog, each one added additional noise and distortion to the signal.
