Internal Structure of the V-1200HD
The V-1200HD comprises a 4:2:2 processing section that supports video formats such as 1080i, and a 4:4:4 processing section that supports XGA and
other computer formats.
With the 4:2:2 section, you can select 2M/E, 1M/E, and other switcher configurations, and use keyers, picture-in-picture, and other forms of
composition.
The 4:4:4 section lets you perform processing of high-quality computer video with no loss in image quality, and provides multi-format support using
scalers. You can also input HDCP-protected video and produce screen-spanning and two-screen video.
The V-1200HD is configured so that output from the 4:2:2 processing section is input to the 4:4:4 processing section, enabling productions of greater
complexity.

* The number of usable layers and AUXes varies according to the M/E settings and selections. You use a V-1200HDR or V-1200HD RCS remote-
control software to make the settings. For details, refer to the “V-1200HDR/V-1200HD RCS Remote Control Guide” (PDF) available for download at
the Roland website.
* EXPANSION IN 1 and 2 and EXPANSION OUT 1 and 2 become usable when an optional expansion interface is installed (p. 14).
* For HDMI IN 3 and HDMI IN 4, you can select whether the connection destination is the 4:2:2 process section or the 4:4:4 process section.
You use the V-1200HDR or V-1200HD RCS remote-control software to make the setting for the connection destination. For details, refer to the
“V-1200HDR/V-1200HD RCS Remote Control Guide” (PDF) available for download at the Roland website.

Memo
You use the V-1200HDR or V-1200HD RCS remote-control software to set the processing format. For details, refer to the “V-1200HDR/V-1200HD
RCS Remote Control Guide” (PDF) available for download at the Roland website.
4:2:2 Process
With the 4:2:2 process, you can input video that is compatible with the selected process format.
Video processed by the 4:2:2 section is output in the same format as the selected format. For example, if the format is set to 1080/59.94i, the format of
video you can input is 1080/59.94i, and the output video format is also 1080/59.94i.
Video processed by the 4:2:2 section is output externally to SDI OUT 1 through 6 and EXPANSION OUT 1 and 2, and also internally to the 4:4:4
processing section.
Selectable 4:2:2 processing formats
1080/59.94i, 1080/50i, 1080/59.94p, 1080/50p
* compliant with SMPTE 274M
* The 4:2:2 process format is set to “1080/59.94i” by default.
* When HDMI IN 3 or 4 is connected to the 4:2:2 process section, video in formats other than the specified 4:2:2 processing format can be input via
HDMI IN 3 or 4. For details, refer to “About Processing Formats” (p. 19).
* The possible number of compositions such as chroma key and picture-in-picture differs according to the selected format and the mode setting.
