Y, Pb, and Pr and HD signal

Question

First off what do all of there stand for? And also aren't they for an HD signal? I just checked on my g-parents older tv and it has Y, Pb, and Pr, so I am just confused. Thanks for the help!

Answer 1

Y, Pb, and Pr is Component video. A Component cable does send an HD signal.

Answer 2

eric is correct, except the y/cb/cr was in use BEFORE y/pb/pr

Y = Luminance

Pb = progressive blue component

Pr = progressive red component



Cb = component blue

Cr = component red

.

these are all analog video signals, it can be HD, but doesn't have to be

HDMI and DVI are digital video signals

Answer 3

Y carries luma (brightness) information.

PB carries the difference between blue and luma (B − Y).

PR carries the difference between red and luma (R − Y).

Basically these three cables replace the YELLOW cable on a Red/White/Yellow component cable,

and carry the video signal.

It is NOT strictly related to HD, it was an early method

used to deliver a more accurate and crisp picture to

monitors.

There is also a Y Cr Cb cable that works strictly

with digital signals.

Some HD systems provide this as an alternate

method of transferring the signal instead of the older

red/white/yellow cables.

However, I would recommend using HDMI cables

for the best picture experience with HD.
