How does EDTV improve video quality compared to SDTV?

EDTV, or Enhanced Definition Television, improves video quality compared to Standard Definition Television (SDTV) primarily through higher resolution. EDTV typically supports a resolution of 480p, which is a significant improvement over SDTV's typical resolution of 480i. The progressive scanning of EDTV means that every frame is displayed in its entirety rather than in interlaced form, resulting in a clearer and more stable image, especially during fast-moving scenes.

This higher resolution allows for greater detail and sharpness, leading to a more enjoyable viewing experience. While other factors such as color options, sound quality, and screen size can enhance the overall experience of television, they do not directly correlate with the fundamental improvement in image quality that higher resolution provides. Therefore, the primary distinction that EDTV brings to the table is its ability to deliver a clearer and more detailed visual representation through enhanced resolution.
