Definition

Noun: A high-definition television system. This refers to a specific technical standard for television broadcasting and display that provides a significantly higher image resolution than traditional standard-definition television (SDTV). The key characteristic is that it has more scanning lines per frame, resulting in a clearer, more detailed picture.

• Often appears in technical, consumer electronics, and media contexts.
