What is the difference?
My old 1999 Sony HD was built before HDMI, but has component.

Component is interesting, You would expect that the three colors would be blue, red and green, the three primary colors in light and TV, tho the red is actually an orange-red plug, to make it different from the familiar audio red. The blue and reddish plugs are chroma, or color. Blue is blue chroma and red is red chroma. Oddly, the green terminal is not chroma, or the green color level, but luma, the overall brightness of the picture. Since we know the overall brightness of the picture the green level is also known as it is simply determined by the subtraction of the red and blue from the total luma brightness. What remains of the luma that is not red or blue has to be the green in the picture.
Disconnect the green luma and the resulting TV picture will be totally black. Swap the red and blue and the red and blue in the picture will be swapped.
The latest trick on the new TVs is to not include a separate yellow composite video input. The green luma plug can also be used as a composite video input, so it is marked half green and half yellow.
That the 3 primary colors are blue, red and yellow (blue and red make purple, red and yellow make orange, yellow and blue make green). But I have also wondered? I realize that HDMI also carries audio signals. But I think that is a downfall. Remember that the more components a signal goes through, the worse it becomes. There is another digital audio..it is via the coax jack. Remember too that component supports 1080p. So there is no reason to have HDMI jacks on a receiver. Newer HDMI receivers usually weigh less too. Me thinks weight is a good sign in components. When I use HDMI cables for video signals I turn off the audio signals on the TV. You want digital audio signals to go to the receiver so that it can send separate signals to each speaker.
With electronics the 3 primary colors are red, green and blue and a subtration method is used as opposed to the additive method you mentioned.
Simply put, component is analog. HDMI is digital.
Yes.
Also, you can't normally upscale (e.g. DVD) over component. Lots of "legal"/electronically-enforced restrictions in effect re the use of analog/component video (too easy to copy).
tesla can use 1080i video from a BDP with component, if his TV accepts that res and his BDP is "old" enough to have it, 1080i actually looks very decent with a BD, compared to DVD.
Also, HDMI carries video AND audio. Component connections are video only.
