Active vs. Passive Stereoscopic 3D
Each video frame on a MPEG4-MVC 3D Blu-ray is designed to be shown in a frame sequential manner with a frame provided for each eye (left and right) that combine to create a single 3D image.
The display type determines the way 3D images are displayed:
Active 3D TVs display 3D content in frame-sequential format, where the left eye and right eye images are separated and alternated. This is done 48 times per second or 24 times per eye. Battery-powered 3D glasses use active shutters to open and close each eye in time with the image on-screen.
Passive 3D TVs are limited to showing a single image that interweaves each eye onto a single frame. The display and 3D glasses use a polarizing filter, where only the portions of the screen meant for each eye are visible.
