One uses multiple simultaneous projectors and the other uses alternating scans.

Imax 3D and RealD are digital 3D systems. Each of these systems projects a greater number of images per second than regular film – regular film is 24 frames per second, IMAX 3D is 96 frames per second and REALD is 144 frames per second. The lenses of the Digital 3D glasses are polarized – each eye is polarized differently so you can see the 3D image. You can’t play digital 3D movies on your computer becasue of the frame rate (or at home on your TV). Those are anaglyph 3D and create the 3D effect with color layers – you use the red and blue glasses to see those.

Theaters use polarized light with the image for the left eye having a different polarization form the right eye. The problem is televisions and monitors can’t do polarized light, at least they haven’t found a way to do it so far. So the movie makers have only two other choices for tv. Use the red and blue glasses, or do the shutter glasses that must be plugged into a power supply or use batteries. I had a field sequencial 3d system that works with the old tube televisions a few years ago, it used shutter glasses, does not work with lcd or plasma. They are now starting to make lcd and plasma that can do shutter glasses. They must have higher flash rates to handle the double images.
Also for the red and blue glasses you don’t need any special equipment to use it. Anaglyph 3d will work with any television and dvd player. The only problem one would have with this format is the tinting color of the tv has to be just right so it matches the color of the glasses, otherwise the 3d effect won’t work. Getting the color right is just trial and error until you get it right.
