G.E. ceased production of its 3 x I.O., the type PC-25 in 1966. Meanwhile, the company had brought out, in 1965, a 4-tube vidicon camera, the GE PE-24, for film scanner use.

Four 30 mm tubes allowed one tube to be dedicated solely to producing a relatively high resolution monochrome signal, with the other three tubes each providing red, green and blue signals.
Apollo 7 slow-scan TV, transmitted by the RCA command module TV camera. NASA decided on initial specifications for TV on the Apollo command module (CM) in 1962. [2] [ Note 1] Both analog and digital transmission techniques were studied, but the early digital systems still used more bandwidth than an analog approach: 20 MHz for the digital system, compared to 500 kHz for the analog system.
