An apparatus for processing a stereo three dimensional video includes a memory to store an encoded stereo three dimensional (S3D) video frame of the stereo three dimensional video, where the S3D video frame comprising a left frame, right frame, and depth frame. The apparatus may include a processor to retrieve a pixel (x,y) of the depth frame, the pixel (x,y) comprising a reference device depth(x,y). The apparatus may also include a device aware decoder component to determine pixel pair positions for a left pixel in the left frame and right pixel in the right frame based upon the pixel (x,y), and to calculate a target device disparity for the pixel (x,y), based upon the reference device depth(x,y) and a screen size of a target device to present the S3D video.
