What describes a television format with significantly higher resolution than standard signals?

High-definition television (HDTV) represents a television format that offers significantly higher resolution compared to standard definitions. This increased resolution provides a clearer and more detailed picture, enhancing the viewing experience. HDTV typically has a resolution of either 720p, 1080i, or 1080p, which means that the images displayed have more pixels and finer detail, allowing for a much sharper image than that provided by standard definition television.

The distinction is important in today's visual media landscape, as many content creators produce programming specifically designed for high-definition formats, optimizing the visuals for larger screens and higher-quality displays. In contrast, other options such as cable formats, satellite services, or even standard cable television do not inherently guarantee the same level of resolution as HDTV does. Therefore, high-definition television stands out as the correct choice due to its primary characteristic of significantly enhanced image clarity and resolution.
