HD3G7 HD 3 Gb/s SDI Video Generator
Converter Mode: The fi gure below shows an example STATUS display when
the module is in the converter mode.
Converter (3G-A): Indicates that the incoming HD SDI video stream is
being converted.
1080 59.94i: Indicates the incoming signal format. If there is no input or
the format is not the correct rate, the following messages will appear on the
second line of the LCD: “No Input Signal” or “Input Signal Error (Check
FORMAT)”.
YCbCr 4:2:2 10b: Indicates the output sampling structure.
OUTPUT MODE Submenu
Select Level A or Level B as the serial link multiplexing method. Use the left ( ◄ )
or right (
► ) arrow button to select Level A or Level B . Press the ENTER button to
con fi rm the selection. The following fi gure shows the OUTPUT MODE submenu.

Level A. This is one way of constructing the 3 Gb/s serial data stream, as
described in SMPTE 425. For the mapping structure 1 signals (1080p50,
1080p59.94 and 1080p60), a Level A stream looks similar to HD video (as de
fi ned
in SMPTE 292), except the data rate is twice as fast and the lines are sent in order,
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 SMPTE 425 standard
for details on the Level A mapping method.
Level B.
This is an alternate way of constructing the 3 Gb/s serial data stream,
as described in SMPTE 425. For the mapping structure 1 signals (1080p50,
1080p59.94 and 1080p60), a Level B stream looks similar to dual link (as de
fi ned
in SMPTE 372M). The serial data is constructed by interleaving two lines of
video. As a result, the serial data takes two lines worth of time to propagate.
This has implications for the effects of the pathological signals, and can confuse
the de
fi nition of timing adjustments. Refer to the SMPTE 425 standard for
information on other mapping structures.
2k × 1080. Available in both Level A and Level B mapping, this selection
provides 2048 × 1080 resolution signals, primarily for digital cinema applications.
