Enhanced for 16:9

For DVD, refers to a program where the entire 720 by 480 pixel video frame represents a 16:9 aspect ratio image. Whereas for a "standard wide screen" program, only the middle 720 by 360 pixels represent a 16:9 image with the topmost and bottommost pixels unused (see "letterbox"). To show the full resolution, the  enhanced program must be viewed on a TV or monitor with an adjustable image height control or a 16:9 aspect ratio screen. The exact number of pixels of picture height excluding letterbox bars will vary depending on the exact aspect ratio of the image, although the enhanced version will still have better resolution than a standard letterbox edition. A DVD player optionally reconstructs the picture with some loss of vertical resolution to be viewed on a standard TV set without a height control. Enhanced wide screen programs may also be labeled "anamorphic" or "high resolution".
