What resolution indicates high-definition in the Axis naming conventions?

High-definition (HD) in the context of video resolutions refers specifically to a minimum standard that enables significantly clearer and more detailed images compared to standard-definition formats. The Axis naming conventions classify 1080P, which is 1920x1080 pixels, as high-definition. This resolution supports a widescreen format and is commonly used in both consumer and professional video applications, making it a recognizable standard for HD content.

In contrast, the other options represent lower resolutions that do not meet the criteria for high-definition. SVGA at 800x600, 4CIF at 704x480, and VGA at 640x480 all fall into standard-definition categories, providing less detail and clarity compared to 1080P. Thus, the choice of 1080P as the indicator of high-definition aligns perfectly with industry standards for HD video quality.
