How come the video outputs on newer TVs are Red, Green and Blue? Wouldn't it make more sense if it be Red,
Wouldn't it make more sense if it be Red, Blue and Yellow?
Answers:
those might be different cable like component for hd. the ancient ones are called composite.
Yellow is reserved for composite video.
Red, Green and Blue are the primary colors of light. The innovative analog RGB component inputs used a separate cable to carry respectively component of the signal, along with a separate sync cable.
Modern equipment uses the colorless YPbPr standard, but the cable colors carried over -- a throwback to the closer component standard. (The sync signal is usually carried on the Y wire.)
The 'Y' cable within YPbPr is the "luma" cable. The letter comes from the Society of Motion Picture and Television Engineers, who recommended 'Y' to denote luminance surrounded by Engineering Guideline 28. (It doesn't stand for "yellow".) Actually, for video, the primary colors are red, blue, and green. If you still have an dated CRT TV, if you look very particularly closely, you'll see that the picture is actually made up of dots of red, blue or green.
However, RBG outputs you're discussion about are for a component video nouns. I don't know why they chose RBG for them, since:
1: Other video connections use RBG because that's really what each cable carry.
2: Red is also used for the right stereo channel (that's what the red audio cable carry - white is the left channel)
With component video, the 3 signals are Y (green), Pb (blue) and Pr (red). They don't pass images contained by red, blue or green, but rather refer to things approaching black levels and synchronization signals. You can look up component video on Wikipedia for a more detailed hi-tech description.
