Question text

After filtering, digitized video is converted from the YUV color scheme (used in NTSC) to

the RGB (primary additive) color scheme used in computers.

Select one:

True

False

Feedback

Correct! The human vision system is more sensitive to changes in luminance than in color,

thus digital video is stored in the YUV color scheme that television uses, which allows for

separate luminance and chrominance sampling in the digitization step.

Of course a better question to ask might be how many "unique URLs on the web" exist?And of course this needs to be asked of the search engine which is now a verb.
