выход - Y/Cb/Cr, вход - Y/Pb/Pr уживутся?

Just red (pun intended!) on Cnet.com
that: "This separation is most
frequently labeled Y, Cb, and Cr for
DVD players and other standard video
sources. HDTV sources can display a
wider color palette, and their
component video connectors are labeled
Y, Pb, and Pr to differentiate them.
However, we've found that many
manufacturers mislabel their component-
video connectors. For example, some
analog Sony TVs have jacks labeled Y,
Pb, and Pr, but they cannot accept HDTV
signals. The most common connection
from DVD players is three RCA-type
jacks."
