Discussion Overview

The discussion revolves around calculating the data rate for an SXGA display, focusing on the relationship between color depth, frame rate, and resolution. Participants explore the formula for determining data rate based on these variables.

Discussion Character

  • Technical explanation, Conceptual clarification

Main Points Raised

  • One participant suggests that to calculate the data rate, one should multiply the number of bits per pixel by the number of pixels on the screen and the number of frames per second.
  • Another participant confirms this approach and inquires if, in an 8-bit color system, 8 bits are dedicated to each pixel.
  • It is noted that generally, 8 bits per color channel results in a total of 24 bits for RGB color representation.
  • A subsequent participant asks how to determine the number of bits per pixel for a 24-bit color system, questioning if it is simply 24 bits per pixel.

Areas of Agreement / Disagreement

Participants generally agree on the formula for calculating data rate, but there is some uncertainty regarding the breakdown of bits per pixel in different color systems.

Contextual Notes

There are assumptions regarding the definitions of color depth and pixel representation that are not fully explored, and the discussion does not resolve how to handle variations in display configurations.

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.
