== Summary ==<br />
Indicates the user's preferred window aspect ratio and conversion method. <br />
<br />
== Description ==<br />
Defines enumeration that indicates the user's preferred<br />
window aspect ratio and conversion method.<br />
Remarks<br />
Indicates the user's preferred window aspect ratio and<br />
preferred method of conversion of 16 x 9 content to a 4 x 3<br />
window aspect ratio. Pan-scan and letterboxing are the two<br />
conversion methods. Displaying a video at the largest<br />
possible size inside the display window without any cropping<br />
or stretching is called displaying in letterbox format.<br />
Pan-scan is specifically cropping a 16 x 9 video for display<br />
in a 4 x 3 window using parameters defined by the video<br />
author.<br />
<br />
<br />
<br />
This enumerated type indicates a preference of conversion<br />
mechanisms because some content can only be displayed using<br />
one of these methods. Content that is 4 x 3 is always<br />
converted to a 16 x 9 window by using sideboxing, where black<br />
bars are added to the right and left sides of the display<br />
instead of the top and bottom of the display as in the 16 x 9<br />
to 4 x 3 conversion using letterboxing.<br />
<br />
<br />
<br />
The following table shows the conversion method used between<br />
the actual content type listed in the first column, and the<br />
user display preference setting, indicated by one of the<br />
other columns.<br />
