3D SYNC INPUT MODE NOTES
Select the option matching your source type and how the 3D sync is supplied:
• Use GPI: Select only if using a single 3D signal requiring a separate 3D stereo sync input at the GPIO.
• Use Selected Input Port: Select if your 3D source provides separate left and right data via 2 cables at the
HD-SDI A and HD-SDI B SMPTE ports. This assumes the 3D stereo sync signal is included with the image
data inputs rather than supplied separately at the GPIO port.
• Use White Line Code: Select only if using a single 3D input signal in which an embedded white line at the
bottom of each frame identifies left vs. right, and an additional separate 3D stereo sync input at the GPIO
port is not present. The bottom row of the left-eye sub-field should be pure white for the left-most 25% of the
pixel row and pure black for the remainder of the row. The bottom row of the right-eye sub-field should be
pure white for the left-most 75% of the pixel row and pure black for the remainder of the row.
• Use Line Interleave: For use with 3D source data only. When specified, the TI system will de-interleave
each line into the left image or right image in memory as specified. Line interleave can be used with PsF 3D
data (left and right data for one field, then left and right data for second field).

Control Description
6: L/R Display
Defines frame order (L-R or R-L) required for 3D perspective. Correct setting ensures
smooth motions and depends entirely on the original source mastering. This option
Sequence
only has meaning when the Frame Rate factor M is equal to 2. For this case, 2 input
frames of data are required to constitute a complete frame of image data. This parame-
ter tells the system which frames go together to make a complete image. NOTE: When
using Line Interleave as the 3D Sync Input Mode, ensure that Left (L1R1 L2R2) is
selected.
7: 3D Sync
Keeps 3D stereo sync output the same as input (true) or reversed (inverted).
Polarity
True: 3D L/R sync output from GPO will match L/R sync input.
Inverted: 3D L/R sync output from GPO will be the opposite of sync input (left =
right, right = left).
8: Dark Time
Create a blank time interval between left and right frames to allow for LCD shutter
glasses, Z screen, or rotating 3D wheel to synchronize the output. See Dark Time and
Output Delay Notes below. Values between 0 and 65535 are accepted. Click the
Launch Dialog button to enter the dark time value.
9: Output
Non-image time in Microseconds (µ). Offset 3D stereo sync output in relation to dark
time interval. See Dark Time and Output Delay Notes below. Values range between
Delay
-32768 and 32767 are accepted where a positive offset = delay and negative offset =
start early. Click the Launch Dialog button to enter the output delay value.
10: Phase Controls the degree of reference between the L/R sync output. A vertical adjustment is
typically required when using a z-screen. Values between -180 and 180 are accepted.
Delay
Click the Launch Dialog button to enter the phase delay value.
