High-definition television; a digital television broadcasting system with higher resolution than standard television formats.
Modern acronym formed from 'High Definition Television,' coined in the 1980s as broadcast technology evolved. Each component reflects technological advancement: 'high' indicating superior quality, 'definition' from Latin 'definire' (to set boundaries), emphasizing clear image boundaries.
