Which example below represents four times the subcarrier frequency as the sampling rate for the luminance portion of the signal, and two times the subcarrier frequency for each of the color difference signals.
A) 4:2:2
B) 4:4:4
C) 4:4:4:4
D) RS422

Question

Quizplus · Accepted Answer

The 4:2:2 chroma subsampling format means that the luminance signal is sampled at four times the subcarrier frequency, and each color difference signal (chrominance) is sampled at twice the subcarrier frequency, matching the description.
