# Multi-aspect feature
DVD supports Squeeze system whereby full-spec information of wide-aspect images is compressed to 4:3 images and stored on a disc. With a wide-screen TV, squeezed images are returned to 16:9 wide-aspect images in Full mode for reproduction of high-quality images. With a 4:3 TV, squeezed images are reproduced in Letter-box format or Pan & Scan. With Letter-box, wide-aspect images are displayed on a 4:3 screen with black margins at top and bottom of the image, and with Pan & Scan, some portions of wide-aspect images are deleted to fit a 4:3 format.
