Select SD or HD m
ode, or set the 3G-SDI serial link multiplexing method to
Level A or Level B (Option 3G only). Use the left (◄)orright(►) arrow button
to select from the choices listed below. Press the ENTER button to confirm the
selection. The following figure shows the OUTPUT MODE submenu.

SD. The ou
tput is a SMPTE 259 compliant signal that runs at 270 Mbps.
HD (1920 × 1080). The output is a 1080-line, SMPTE 274M compliant signal.
HD (1280 × 720). The output is a 720-line, SMPTE 296M compliant signal.
Level A
. (Option 3G only) This is one way of constructing the 3 Gb/s serial data
stream, as described in SMPTE 425. For the mapping structure 1 signals such as
1080p50, 1080p59.94 and 1080p60, a Level A stream looks similar to H D video
(as defined in SMPTE 292), except the data rate is twice as fast. In Level A, the
lines are sent in o rder, consecutively. For other mapping structures, the video is at
a lower frame rate, but has more bits and/or includes more channels. Refer to the
SMP
TE 425 standard for details on the Level A mapping method.
Level B. (Option 3G only) This is an alternate way of constructing the 3 Gb/s
serial data stream, as described in SMPTE 425. A Level B stream looks similar
to dual link (as defined in SMPTE 372M). The serial data is constructed by
interleaving the two links of the dual link video signal. As a result, some
f
ormats will have the serial data take two lines worth o f time to propagate.
This has implications for the effects of the pathological signals, and can
confuse the definition of timing adjustments. Refer to the SMPTE 372M and
SMPTE 425 standards for more information.
2K × 1080. (Option 3G only) Available in both Level A and Level B mapping, this
selection provides 2048 × 1080 resolution signals, primarily for d igital cinema
applications.
2×HD. (Option 3G only) Available in Level B mapping, 2×HD signals provide two
standard SMPTE 292 HD streams in the same format (for example 1080i 59.94).
Select between Test Signal/Test Signal or Test Signal/Black for the two streams.
