DGA-6000 ULTRA-HD VIDEO GENERATOR / ANALYZER USER MANUAL
18
3D Mode
Structure
– Select 3D Off (2D), 3D Frame Packing, 3D Side-by-Side (Half), or 3D Top-and-Bottom
Structure video signals. The Structure is also shown at the bottom-right corner of the OSD Menu.
After a 3D structure (e.g. Frame Packing) is selected only valid video formats (e.g. 1080p24) for that 3D
structure can be enabled. If the current DGA-6000 video format is not one of the provided video formats
for the selected 3D structure, the generator will automatically switch to a valid video format. Pressing
the front panel Format button will skip over formats that are not provided for the selected 3D structure.
Invalid formats selected by the IR remote control will be ignored. A unique USB command is also
available for each valid 3D structure and video format combination (see the USB Format command
table).
No standard-definition 3D formats are provided. Therefore, to return to a standard-definition format
(480i/p or 576i/p) the user must first select 3D Off in the Structure menu to return to the 2D mode.
Blank Eye
– Select None, Left or Right. Blanks the left or right eye image for all 3D signals. This can be
used to identify or troubleshoot faulty 3D processing by a display or processor.
Infoframe
– Select Infoframe On or Off. A CTA-861 Vendor Specific Infoframe is normally sent from the
DGA-6000 to the display (or video processor) to identify the video signal’s 3D Structure. A 3D display, or a
3D compatible processor, uses the Infoframe information to correctly process and/or display 3D signals.
Side-bySide (Half) and Top-and-Bottom 3D structure signals contain both left eye and right eye half-
horizontal-resolution or half-vertical-resolution images respectively in a single 2D compatible video
frame. Therefore, if the Infoframe is turned off, a 3D display will simultaneously show the half-resolution
left-eye and right-eye images in a single 2D image frame, unless the display’s manual controls are used
to select a corresponding 3D display mode.
However, most 3D displays automatically sense 3D Frame Packing structure signals without using the
Infoframe. Therefore it’s usually not possible to view the left and right eye images of 3D Frame Packing
signals within a 2D frame even though the Infoframe is turned off.
2D Displays will simultaneously display the left-eye and right-eye images of the 2D frame-compatible
Side-bySide (Half) and Top-and-Bottom 3D structure signals, however the Infoframe may need to be
turned off else the display may report that an invalid signal is being received. Most 2D displays are not
compatible with the unusual video frame formats used for Frame Packing signals and therefore will
report that an invalid signal is being received.
Crosstalk
– Select Crosstalk to produce a special test pattern to measure the amount of 3D crosstalk
between left eye and right eye images as seen through 3D glasses. The amount of crosstalk is a function
of both the 3D display and its 3D glasses. See
Using the 3D Crosstalk Pattern
in Appendix A
.
CAUTION: Always use CAUTION when displaying any test patterns. Static patterns,
particularly bright patterns, can produce permanent image retention (“burn-in”) on
some display products. 3D display products may be more susceptible to image
retention than other display products. Consult the display manufacturer for guidance
BEFORE using test patterns from any device.
Tip: Always display patterns for the minimum amount of time necessary to make
measurements or adjustments. The Mute button produces a black field and blanks
menus.
