Component
The HD/SD Analog Video Section (Figure 3-3)
provides either HD or SD component input and
output. The HDX-SDI provides 10-bit analog
performance with 12-bit A/D and D/A converters.
In general, component video signals tend to be
higher quality than composite or S-video, so to
take full advantage of the component format, be
sure to use high quality shielded BNC cables.
Configuring the analog video section
The HDX-SDI component input and output
supports YPbPr or RGB operation, as shown by the
labeling below the connectors in the Analog Video
section. Accordingly, the input and output jacks in
this section can be independently configured for
one of three different analog video formats:
Component RGB
■
Component YPbPr
■
Composite + S-video
■
This setting is made in the MOTU Video Setup
software. For the component inputs, see "Input
Source" on page 34. For the component outputs,
see "Analog Output Mode" on page 37. Be sure that
the mode you choose for each bank matches the
component video source or destination to which it
is connected. If the device you are connecting
supports both RGB and YPbPr, use YPbPr, as it is
the standard for broadcast video.
☛
Analog YPbPr component video is sometimes
referred to by other names, such as YUV,
Y/R-Y/B-Y or YCbCr.
SD (480i) component formats
The HDX-SDI supports four different SD
component formats: SMPTE/EBU N10, Sony Beta,
Sony Beta Japan and Panasonic MII. This setting is
made in the MOTU Video Setup software. See
"480i Component Levels" on page 37 and "480i
I N S T A L L I N G T H E H D X - S D I H A R D W A R E
Setup" on page 37. For PAL (576i) and HD
component operation, the HDX-SDI supports the
industry standard SMPTE/EBU N10 specification.
HD-SDI and SD-SDI
The HDX-SDI provides HD-SDI or SD-SDI input
and output in professional, broadcast quality
10-bit 4:2:2 resolution. A second, duplicate SDI
output is provided, allowing you to connect a
second SDI output device. For example, you could
connect both an HD monitor and an HD video
deck.
For best results, be sure to use cables that are
designed for SDI use (such as Belden part number
8281, or similar). The HDX-SDI has been designed
to support SDI cable lengths up 500 feet with SDI
rated cables.
HDMI
The HDX-SDI provides HDMI input and output in
professional, broadcast quality 10-bit 4:2:2
resolution. The input is ideal for capturing video
from HDMI-equipped cameras, many of which
send the video signal to their HDMI output before
it is compressed in the camera.
The HDMI output can be connected to any device
equipped with an HDMI input, such as a plasma
screen, LCD screen or even a home theater receiver.
The HDX-SDI supports up to 8 channels of PCM
(uncompressed) audio output via the HDMI
connection for devices that can receive digital
audio via HDMI.
DVI output
Using a HDMI-to-DVI cable, or a female HDMI-
to-male DVI plug adaptor connected to one end of
an HDMI-to-HDMI cable, you can connect the
HDX-SDI's HDMI output to the DVI input of
another device, such as a computer monitor. In
addition to the cable connection, you also need to
