CCIR vs EIA

CCIR stands for Comittee Consultatif International Radiotelecommunique. This is the committee that recommended the standards for B/W television accepted by most of Europe, Australia and others. This is why when we refer to equipment that complies with the B/W TV standards we call it CCIR compatible. The same "type" of standard, but later extended to colour signals, was called PAL. The name comes from the concept used for the colour reproduction by alternate phase changes of the colour carrier at each new line, hence: Phase Alternate Line-PAL.

EIA stands for Electronics Industry Association, an association that created the standard for B/W television in the USA, Canada and Japan, where it is often referred to as RS-170, it being the recommendation code of the EIA proposal. When B/W TV was upgraded to colour, it was named by the group that created the recommendation: National Television Systems Committee, or abbreviated NTSC.
