The difference is that whilst D1 has a 4:3 aspect ratio 960H has a 16:9 widescreen aspect ratio. The extra pixels are used to form the increased area to the sides of the D1 image. The pixel density of 960H is identical to standard D1 resolution so it does not give any improvement in image quality, merely a wider aspect ratio.

Standard definition—480i, to maintain compatibility with existing NTSC sets when a digital television broadcast is converted back to an analog one [citation needed] —either by a converter box or a cable/satellite operator's proprietary equipment; Enhanced definition—480p, about the same quality as DVDs; High definition—720p; High ...
Better image quality. ATSC 3.0 allows UHD transmission, including high-dynamic-range television (HDR-TV), wide color gamut (WCG), and high frame rate (HFR). Reception upgrades. ATSC 3.0 allows the same aerial to receive more channels with better quality. Portable devices such as mobile phones, tablets, and car infotainment systems can receive ...
Low-definition television (LDTV) refers to TV systems that have a lower screen resolution than standard-definition television systems.
