The Apollo Lunar Television System

A limited, spacecraft transmission bandwidth has been used in the development of the Apollo Lunar Television system. Using 10 frames/sec and 320 non-interlaced scan lines, the system provides nearly commercial-quality TV pictures. A portable TV camera employing microcircuits is used onboard the spacecraft and on the lunar surface. Reiterative processing of the video signal is used in the scan conversion of the slow-scan TV signal to obtain a flicker-free commercially compatible picture at the home television receiver.
