Component YPbPr to Component HDTV Input
Most HD ready display monitors have inputs that accept a component video signal. A component
video signal has (3) signals including luminance (Y), a scaled red color difference signal (Pr),
and a scaled blue color difference signal (Pb). Analog composite sync is included on the Y
signal. The component video signal provides a high bandwidth interface using only 3 separate
signals nicely supporting the resolution bandwidth required by HDTV/SDTV signals. A
component video interface has become the most popular method of interfacing analog signals
from a satellite, terrestrial, or cable HDTV receiver to a display. An HDTV/SDTV component
video generator may be used to substitute for HDTV component video signal sources when
aligning or troubleshooting HDTV/SDTV video equipment.
To test the component video input (YPbPr),
connect the DVI to BNC test lead cable
(39G1059) from the generators DVI output to
the display’s Y, Pr, and Pb inputs. You will
likely need to use the BNC to RCA adapters
(26G1255) to connect to the phono plugs
commonly used as display inputs.
Select the HDTV/SDTV –YPbPr signal type
from the generator menu. Select a resolution
format from the Format menu. Use 480i29 for
testing SDTV and 1080i29 for testing the
HDTV display operation. Select the
component video input from the
receiver/monitors input menu screen. The
receiver/monitor should process the
component video signal and display the video
test pattern. Select the desired test pattern
from the generator’s Pattern menu.
