Data Rates

[questions_uk]

If you have an x bit SXGA colour display operating at an equivalent frame rate of x Hz, to calculate the data rate would you just multiply these two variables together?

Thanks.

Simply multiply the number of bits/pixel * number of pixels on screen * number of frames/second

Thanks! So if you have an 8 bit colour system for example, this means 8 bits are dedicated to each pixel?

Generally 8bits/color = 24 bits RGB overall.

Ah ok thanks. So if you had 24 bit colour, how would you work out the number of bits to each pixel? Or is it just 24 bits per pixel?

Thanks.
