Figure 20. Horizontal Format

The Horizontal Format has the following controls.

	Square Pixels	Use the Square Pixels setting for normal 4:3 video (Figure 20) that is viewed
	Square Pixels	via a computer monitor. This setting results in a square aspect ratio sampling

		of the source video. This results in 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
	CCIR-601	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, it 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.

	16:9 Wide	Select 16:9 Wide for 1.85:1 anamorphic video such as DVD content and any
	16:9 Wide	widescreen content. The output video size is 852 x 480 for 525-line standards,

		and 1024 x 576 for 625-line standards. To actually see output of this size, you
		have to also select this size in your application.

	Use WideScreen	The Use WideScreen Signal (WSS) control enables automatic sidebars and
	Use WideScreen	letterboxing when the input video aspect ratio does not match the output
	Signal (WSS)
	Signal (WSS)	aspect ratio. If the aspect ratio of your content is subject to change between

		16:9 and 4:3, it is useful to enable this control.
