    I Analog TV reception in a spacecraft moving relative to the Earth

    The scan conversion consisted of three components - twin VTRs sharing a tape to allow for Doppler, a TV set to display the incoming 320 line 10 frame signal from Apollo with (I think) a standard NTSC 525 line TV camera recording that picture along the lines of a kinescope, and a magnetic disc...

We know they originate from Earth because they are live TV transmissions that were received by network TV and recorded on video that is available in the...
