ITU-R Rec. BT.601-5,
Studio
encoding parameters of digital tele-
vision for standard 4.3 and wide-
screen 16:9 aspect ratios.
Should
this standard be revised, it will be
denoted Rec. BT.601-6.
Recall from page 90 that in
Rec. 601,
C- B
and (R are
cosited-
each is centered on the same
location as ~', wherej is even.
Most 4:2:2 systems now accom-
modate lO-bit components.
This chapter provides an overview of digital interfaces
for
uncompressed
and
compressed
SDTV and HDTV.
