17. Passive 3D application and 3D format conversion
17.1. Passive 3D System Configuration
G900 can support 3D signal from all kinds of 3D video sources, including Blue Ray DVD, STB, Media
player, Game console
and PC… 3D signal will be decoded by G900 into signals for Right/Left eyes for
passive 3D application or convert into specific 3D format for 3D display devices. The signal for
passive 3D needs to be displayed through two projectors. Two projector images need to be stacked
on the screen through geometry alignment function in the projector. Each projector will display signal
only for one eye. User needs to set a polarized filter in front of the projector and also wears polarized
glasses. The glasses need to match the polarized filter in front of the projectors so that the right eye
can only see the scene for right eye and the left eye can only see the scene for left eye. Silver coating
3D screen is required to preserve the polarization of the light for 3D display. It is possible to use optic
spectrum method from Infitec or Enciircle Inc.
to allow 3D displayed on conventional 2D screen.
17.2. Passive 3D System installation and setup
➢
GeoBox should not be installed at side of the projector where the ventilation hot air comes out.
➢
Two projectors can be put side by side or top/bottom. Closer lens position will reduce geometry
adjustment range and reduce the loss of the image resolution and brightness. Please make sure
hot ventilation air will not affect the other projectors.
➢
Set output resolutions from 3D signal source as high as possible and connect to HDMI input of
GeoBox, then daisy chain connection to another channel.
➢
GeoBox will decode and distribute RH/LH eye signals for two projectors.
