ASTRA is the home of HD television


High definition (HD) TV is a new broadcasting format that delivers better quality pictures to your TV screen. The HD television channels give images with richer colours and up to five times more detail, so your viewing experience is more vivid, dramatic, and gripping.

An HDTV image typically contains around two million (1080x1920) picture elements, or pixels. That’s around five times more detail than the 720x576 of a standard definition (SD) picture, and makes HD broadcasts more realistic and involving.

Coupled with an HD-ready TV set, the 16:9 widescreen picture format, and the superior sound systems built into HD TV sets, such as the 5.1 Dolby Surround system originally developed for feature films, watching HDTV really makes you feel like you’re part of the show.

Films, costume dramas, documentaries and sports all benefit from high definition – but whatever type of programmes you like to watch, it will look better in HD.

Because an HD transmission uses more broadcasting capacity, terrestrial digital and digital cable TV have room for only a few HD channels. Our ASTRA satellites have room for far more, and already European viewers can receive more than 150 HD channels via ASTRA.
