Theatrical 3D Visualizer Troubleshooting/FAQ’s

Hardware / Drivers

Q: How does the hardware connect to a user's system?
A: The VRex Theatrical IR transmitter is connected to the Digital Content server, aimed at the screen thru the Projection booth window. The existing theatrical Screen is excellent for Stereoscopic 3D viewing with no further modification. No other connections are required.

Q: If the system is not being used, does it mess up the standard format Digital Cinema content?
A: No

Q: Does you system use the COM port, Parallel Port, or Keyboard port for power?
A: No. The system uses batteries. There are no connections needed.

Q: How long will the batteries last?
A: The batteries will support up to about 500 hours of continuous 3D operation.

Q: Does the system consume power when it is not being used?
A: No.

Q: Does the system support the advanced page-flipping and high-speed interlaced video modes of some special graphics cards?
A: Yes. The system can be put into an advanced mode that supports page flipping, interlaced video modes.

Q: Does the system use line-blanking technology?
A: Yes.

Q: What is line-blanking?
A: Line-blanking is a technique of alternately "removing" or blanking video information in synchronization with the shutting glasses. Line-blanking is a two step process which takes two video scans to complete. In the first step, the line-blanking electronics remove the left image from the video information (by replacing the video data with black pixels) and open the right eye shutter. In the second step, the line-blanking electronics remove the right image from the video information and open the left eye shutter.

Q: Can more than one unit be driven by the VRex Theatrical IR ?
A: Yes. Every unit that is in visual range of the screen will be driven .

The theater owner can open the battery area and pop out the batteries, with a special tools that is supplied with the order. The system uses two low-cost watch batteries that can be found at almost any store that sells watches or electronic items.

Q: What format is the 3D stereoscopic video in?
A: The Theatrical 3D Visualizers uses a line-alternate or interleaved format. Each row or line of video alternates between the left eye and the right eye (from top to bottom). JPEG 2000 generates this format automatically with the appropriately formatted content.

VR Visualizer Troubleshooting/FAQ’s

Hardware / Drivers

Q: How does the hardware connect to a user’s system?
A: The user simply unplugs his/her monitor from the video card and inserts a small dongle between the monitor cable and the video card. There are no other connections to make. You do not need to open up your computer and you do not need to reboot your system.
Q: If the system is not being used, does it mess up the video?
A: No

Q: Does you system use the COM port, Parallel Port, or Keyboard port for power?
A: No. The system uses batteries. There are no connections to parallel, serial, USB, keyboard, or joystick ports.

Q: How long will the batteries last?
A: The batteries will support up to about 100 hours of continuous 3D operation.

Q: Does the system consume power when it is not being used?
A: No.

Q: Does the system support the advanced page-flipping and high-speed interlaced video modes of some special graphics cards?
A: Yes. The system can be put into an advanced mode that supports page flipping, interlaced video modes, and multiple units on the same PC.

Q: Does the system use line-blanking technology?
A: Yes.

Q: What is line-blanking?
A: Line-blanking is a technique of alternately “removing” or blanking video information in synchronization with the shutting glasses.

In the second step, the line-blanking electronics remove the right image from the video information and open the left eye shutter.

Q: Can more than one unit be attached to a single PC?
A: Yes. Each additional unit that is attached to the first unit must be switched into the advanced mode.

Q: How many units can be attached together?
A: About 6-8 units.

Q: The viewing glasses are connected to a hand grip and a small dongle with two 15 pin video plugs on it. What are these devices used for?
A: The hand grip is the controller for the system. The user pulls a finger trigger to activate the glasses and pushes a thumb button to reverse the right and left eyes. There is also a recessed switch to put the unit into advanced mode. The dongle is used to connect the VR Visualizer to your graphics card.

HD3 Shutter glasses FAQ’s/Troubleshooting

Problem: I don’t see any 3D effect.
Solution: Be sure the programming you are watching is 3D. If the programming is 3D, you should see a slight double image without the glasses.

Problem: My screen flickers.
Solution: Some people can see flicker when watching a 3D program on a television. To minimize flicker, turn down or turn off the lights in the room while you are watching 3D. The darker the room, the less flicker you will notice.

Problem: The 3D images do not look correct.
Solution: Check to ensure the polarity of the images. The left image should only be seen by your left eye and the right image should only be seen by your right eye. The MODE switch on the H3D control box switches between a left-eye-first and a right-eye-first video format. Be sure you have the H3D system set to the correct mode.

Problem: The 3D images have the correct polarity but the image still does not look right.
Solution: Everyone’s visual system is a little different. The 3D images are formatted for the average head size and eye separation. Try moving closer to or farther away from your monitor until the images can be viewed comfortably.
