Patent ID: 7002618

Claim:
A software method for playing stereoscopic DVD movies on a microprocessor-based system including a DVD player and a video monitor, comprising: providing a DVD that has been encoded with compressed stereoscopic images in a first format; providing program instructions for interactively constructing a filter graph, including: obtaining a DVD signal having video and audio components from the DVD; separating the video components from the audio components; decoding the compressed images; transforming the decoded images into a second format by mapping a plurality of pixels from the first format to the second format, wherein the mapping step creates an index for each pixel for use in rendering the pixels on the monitor, and wherein the second format includes a first image portion and a second image portion separated by a blanking portion, and wherein for a pixel (i,j) located in the first portion, the index is set equal to j*W*H/(h−b)+i/2; and wherein for a pixel (i,j) located in the second portion, the index is set equal to: (j−h−B)*W*H/(h−b)+w+i/2; and wherein for a pixel (i,j) located in the blanking portion, the pixel is unmapped and the index is set equal to −1; and providing the transformed images for display on a monitor.
