Section 3: Operation

Custom: 3D Control Menu

This menu provides numerous controls for adjusting and synchronizing incoming 3D signals (always dual L/R

HD-SDI signals at the SMPTE A and B ports) with each other and with external 3D equipment such as screens,

emitters and glasses. The Custom: 3D Control menu options are summarized in Figure 3-11 and Table 3.6.

Add a check in the Enable checkbox in order to 1) enable 3D display and adjustment parameters 2)

automatically configure the Input and Data Format (on the Custom Page-1 menu). For full 3D application

notes, including a step-by-step tutorial for use, refer to Section

3.10 Working with 3D.

Table 3.6 Summary of Custom: 3D Control Menu Options

CUSTOM: 3D CONTROL MENU OPTIONS

Enable Activate 3D controls and auto-set Input to 292 Dual Input and Data Format to Unpacked 4:2:2 in

the Custom Page-1 menu.

Test For confirming proper Sync Output setting (i.e., which GPO is connected to your 3D peripherals

such as emitters, glasses, etc.)

L/R Input Reference Defines how 3D stereo sync input is supplied (currently ports A and B only). See L/R Input Refer-

ence Notes below.

Input Frame Dominance 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.

L/R Display Reference Always Not Used unless a separate 3D stereo sync input is at GPIO connector. See L/R Display

Reference Notes below.

L/R Output Polarity Keeps 3D stereo sync output the same as input (true) or reversed (inverted). See L/R Output

Polarity Notes below.

Frame Rate Ratio of total # frames displayed to # frames forming complete data. Increase to reduce flicker in

displays < 96 Hz. Max. recommended setting for 2048 x 1080 displays = 5:2. Can be higher in

smaller displays, or decreased if incoming signal is already high enough to prevent flicker. See

Frame Rate Notes below.

Input GPI Select None when 3D stereo sync input is part of source signal at ports A and B. Use GPI 1-7 only

if sync input is supplied to GPIO port.

Display GPI Always None unless 3D stereo sync input is at GPIO connector.

Output GPO Define your GPO sync output for 3D device (glasses or z-screen polarization), using to 1-7

depending on wiring.

Dark Time Adj Create a blank time interval between L/R frames to allow for glasses ON/OFF. Helps synchronize

the output to the viewing.

Output Delay (Time) Offset (in µ) 3D stereo sync output in relation to dark time interval. Positive offset = delay, nega-

tive offset = start early. See Output Delay Notes below.

Figure 3-11 Custom: 3D Control Menu Options

Sets frame rate per # signals -

Ex. 4 = # frames, 2 = # signals.

Sets which GPI to use - Use 1 -

7 if external server is supply-

ing separate 3D sync at GPIO.

Sets which GPI to use - Use

“None” only.

Sets which GPO to use - For

synchronizing 3D stereo

peripherals such as emitter, z-

screen, etc.

Sets time between L/R - A

blanking time for glasses, etc.

to close/open.

Shifts GPO pulse - Pulse timing

is shifted in relation to vertical

frame.

Shifts GPO pulse in degrees -

Not used.

Sets 3D sync output - True or

Inverted.

Sets 3D sync input location -

With source data (Not Used)

or via GPI.

Frame order - For correct L/R

pairing & smooth motion.

Defines source & 3D sync input

type.

Enable 3D Test Pattern.

Toggle 3D function ON/OFF
