Horizontal Format

Figure 26. Horizontal Format

The Horizontal Format has the following controls.

Square Pixels

Use the Square Pixels setting for normal 4:3 video (Figure 26) that is viewed

via a computer monitor. This setting results in a square aspect ratio sampling

 

 

of the source video and a source image of 640 x 480 for 525-line standards and

 

768 x 576 for 625-line standards.

 

 

CCIR-601

Use the CCIR-601setting for 4:3 video that is viewed on a dedicated video

monitor. This setting results in a CCIR-601 aspect ratio sampling of the source

 

 

video. It results in a video input horizontal size of 720 pixels for both 525-line

 

and 625-line standards. This sizing is standard for dedicated monitors but the

 

resulting video appears horizontally stretched (525-line) or squeezed (625-line)

 

on a computer monitor.

 

It is more efficient to set the horizontal mode to match the size of the output.

 

For example, if your target video size is 640 x 480, using Square Pixel sizing in

 

PostProcessing Mode will avoid an unnecessary software scaling step in the

 

driver.

 

On some systems, for reasons external to this driver, 640 x 480 video renders

 

on screen a lot faster than 720 x 480 video – that is, the speed difference is a

 

lot more than the 9:8 ratio of numbers of pixels.
