The advantages of digital terrestrial television, are similar to digital versus analog in platforms such as cable, satellite, and all telecommunications; the efficient use of spectrum and provision of more capacity than analog, better quality images, and lower operating costs for broadcast and transmission (after the initial upgrade costs).
