Enjoy BD/DVD movies on 3D TV using NAS
Most DirectTV uses a 3D TV format referred to as Side-by-Side 3D where the horizontal resolution of the HD image is reduced by half in order to store the left eye and right eye images on a single frame. And the most common Side-by-Side 3D TV format is the Side-by-Side Half where each sub-frame occupies just half the horizontal resolution of a full HD frame, resulting in a 3D image with 960pixels by 1080 lines instead of the 1920 x1080 required for full 1080p content. To create 3D effect from Blu-ray/DVD for 3D TV playback, just choose to rip Blu-ray/DVD to 3D SBS video format.
