Well at least it motivated me to do my own research. It wasn't strictly live as the LEM transmitted to the CSM which only had LOS to earth about 50% of the time for an hour before going behind the moon for an hour. Footage was stored on the LEM until the CSM came into view then it was passed off to earth.
In the band used for video sending vital ship data to Earth, and there was no room left for the standard black-and-white video format of the era: 525 scan lines of data at 30 frames per second, transmitted at 4.5 MHz. So they developed an "oddball format" – 320 scan lines at 10 fps, transmitted at 500 kHz.

Anyone else remember the first 2 weeks on /sci/ when it was good?

The moons of Saturn are always nice and a good way to test your gear by checking how many you can see.
