Working with 3D
A single projector can display 3D images as described below. Such images require a 3D-capable source as well
as additional hardware and cabling in order to be displayed and interpreted correctly in a typical stereo 3D
viewing environment. Images generated from a 3D-cinema source consist of a series of images (frames or
fields) that alternate quickly between two slightly different viewpoints corresponding to the physical
separation of our left and right eyes (called
parallax
). When these frames are displayed with enough speed and
viewed with special glasses synchronized with the left/right frame sequencing, the resulting single perceived
image appears with much the same depth and perspective we sense in the real world. The new full resolution
triple flash hardware (Brilliant3D) includes an FPGA Formatter Interface Board (FFIB), which allows for full
2K resolution using a 6:2 frame rate multiplication (Triple Flash). Triple Flash 3D is reference to a frame rate
that is of a high enough frequency to eliminate flicker as noticeable by the eye. The standard frame rate for
most 2D D-Cinema content is 24 frames per second (FPS) as it is for film. For 3D, the server splits the 3D
content (video signal) into 2 interleaved signals of 24 FPS each by the server, for a total input of 48 FPS into
the projector. The projector’s frame rate multiplication is set to 6:2, meaning the input frame is multiplied by 3
(Triple) for a total frame rate of 144 frames per second (Hz or FPS). For the Brilliant3D hardware, the TI DLP
version 13.1 or higher is required.
3.6.1 What Do I Need for 3D?
The
CP2000-XB
requires a 3D-capable SMPTE source and a few special hardware/software setups described
below. Essentially you will connect two signals (one left eye, one right eye) to the projector, then use the TPC’s
Custom: 3D Control
menu options to define and control the signal processing, synchronizing and output for
devices used in your stereographic 3D display. These settings ensure critical ordering and timing of the
incoming L/R frames so that they merge correctly into a convincing artifact-free 3D display without cross-talk,
ghosting or other artifacts.
System Requirements
•

projector. Includes all standard 3D components
• FFIB (FPGA Formatter Interface Board)
• TPC software v2.3c or higher
• Main projector software v8.0 or higher
• Two HD-SDI cinema signals (left and right) connected to the projector’s SMPTE ports
A
and
B
.
NOTE
:
Use
of a single input consisting of both left and right data is not currently supported.
• Sync Output Device:
• IR emitter for controlling the L/R
gating
(switching) of active glasses
OR
• Pi-Cell polarizer for controlling a screen that has a silver polarization-preserving surface for use with
passive glasses
• Custom 3D Sync Output Cable (GPIO) such as available from RealD:
• For routing the projector’s output sync to your Sync Output Device—connect from the projector’s
GPIO, a
ccessed from underside of the projector) to the emitter or polarizer.
Refer to the
CP2000-XB User
Manual (020-100163-xx)
for
GPIO pinouts and other 3D sync cable details.
• Power supply for your Sync Output Device, typically wired with the custom GPIO cable.
• Proper 3D configuration defined in the TPC’s
Custom 3D Control
menu. For best results, use the 3D inter-
nal test pattern. Refer to the
CP2000-XB User Manual (020-100163-xx)
for more information.
