'Y' is the luma or luminance component and UV are the two "difference" chrominance components that define a YUV color. You can think of the luminance component as the intensity of the color. The letters themselves do not each represent a particular word - think of them more like variables in a math equation. It looks like this:
U = B - Y (blue - luminance)
V = R - Y (red - luminance)
Georges Valensi came up with this scheme and patented it in 1938, and the broadcast industry adopted it. It prevented B&W TVs from becoming immediately obsolete when television switched to transmitting a color signal because a B&W TV could take the color signal and display the colors as shades of gray.
What else can I help you with?
What does the equation v equals u plus at mean and what do the letters stand for?
v = final velocityu = initial velocitya = rate of accelerationt = timeA body, that starts off with a velocity u, and has a constant rate of acceleration a, will have a velocity v after a time t (with appropriate units).
Solve u plus v times u-v when you equals 5i plus j and when v equals i-6j?

How can you use a discriminant to write an equation that has two solutions?
If the discriminant is greater than zero (b^2 - 4ac) > 0, then the equation have two roots that are real and unequal. Further, the roots are rational if and only if (b^2 - 4ac) is a perfect square, otherwise the roots are irrational.Example:Find the equation whose roots are x = u/v and x = v/uSolution:x = u/vx - u/v = 0x = v/ux - v/u = 0Therefore:(x - u/v)(x - v/u) = (0)(0) or(x - u/v)(x - v/u) = 0Let c = u/v and d = v/u. We can write this equation in equation in the form of:(x - c)(x - d) = 0x^2 - cx - dx + CD = 0 orx^2 - (c +d)x + CD = 0The sum of the roots is:c + d = u/v + v/u = (u)(u)/(v)(u) + (v)(v)/(u)(v) = u^2/uv + v^2/uv = (u^2 + v^2)/uvThe product of the roots is:(c)(d) = (u/v)(v/u) = uv/vu = uv/uv = 1Substitute the sum and the product of the roots into the formula, and we'll have:x^2 - (c +d)x + CD = 0x^2 - [(u^2 + v^2)/uv]x + 1 = 0 Multiply both sides of the equation by uv(uv)[x^2 - ((u^2 + v^2)/uv))x + 1] = (uv)(0)(uv)x^2 - (u^2 + v^2)x + uv = 0 which is the equatiopn whose roots are u/v, v/u
How do you make u the subject of the formula 1 over f equals 1 over u plus 1 over v?
1/f = 1/u+1/v Subtract 1/v from both sides: 1/f-1/v = 1/u Multiply all terms by fv: fv/f - fv/v = fv/u => v-f = fv/u Multiply all terms by u: u(v-f) = fv Divide both sides by v-f which will then make u the subject of the formula: u = fv/v-f
Why is YUV format used in video compression over RGB?
YUV format is used in video compression over RGB because it separates luminance (Y) from chrominance (U and V) information. This separation allows for more efficient compression, as the human eye is more sensitive to changes in brightness than color. By reducing the resolution of the chrominance channels while preserving the luminance detail, YUV achieves better compression ratios with minimal perceptual loss in quality. This makes it ideal for broadcasting and streaming applications where bandwidth is a concern.
What does Honda v-tech stand for?
basically it gives u a lil boost when u need it , it kicks in during certain rpm's
What does rvca stand for?
it does not stand for anything, it is pronounced ru-ka, because the V is pronounced like a U, and the literal term Ruca means clothing in Greek
In physics if v equals u plus at how do i change the fumula to make you a or t the subject?
If: v = u+at Then: -u = -v+at or u = v-at (by dividing all terms by -1) a = (v-u)/t t = (v-u)/a
How do you factor you² 2u 1 - v²?
Do you mean: u² + 2u + 1 - v²? If so then= (u + 1)2 - v2= [(u + 1) + v][(u + 1) - v]= (u + 1 + v)(u + 1 - v)
What does the equation v equals u plus at mean and what do the letters stand for?
v = final velocityu = initial velocitya = rate of accelerationt = timeA body, that starts off with a velocity u, and has a constant rate of acceleration a, will have a velocity v after a time t (with appropriate units).
Solve u plus v times u-v when you equals 5i plus j and when v equals i-6j?

What does the v stand for in v-codes?

What do i do to Make U the subject v squared equals u squared plus 2as?
Rearranging: v² = u² + 2as → u² + 2as = v² ________________ writing equation the other way round to get u² on the left → u² = v² - 2as _________________ subtracting 2as from both sides → u = ±√(v² - 2as) ______________ taking the square root of both sides
