Video Sampling
Digital video is a sampled form of analog video. The most common sampling schemes in use today are:
Pixel Clock Horiz Horiz Vert
Rate Total Active
NTSC square pixel 12.27 MHz 780 640 525
NTSC CCIR-601 13.5 MHz 858 720 525
NTSC 4FSc 14.32 MHz 910 768 525
PAL square pixel 14.75 MHz 944 768 625
PAL CCIR-601 13.5 MHz 864 720 625
PAL 4FSc 17.72 MHz 1135 948 625
For the CCIR-601 standards, the sampling is based on a static orthogonal sampling grid. The luminance component (Y) is sampled at 13.5 MHz, while the two color difference signals, Cr and Cb are sampled at half that, or 6.75 MHz. The Cr and Cb samples are colocated with alternate Y samples, and they are taken at the same position on each line, such that one sample is coincident with the 50% point of the falling edge of analog sync. The samples are coded to either 8 or 10 bits per component.
