What are the differences between High Definition television (HDTV), standard definition television (SDTV) and conventional analogue television?
A picture on the TV screen is formed by a large number of small dots called pixels. The higher the number of pixels, the better the picture quality will be. The pictures of conventional analogue TV broadcasting provide a maximum of 720 (horizontal) x 576 (vertical) pixels. Typically HDTV broadcasts provide a resolution of at least 1024 horizontal pixels and 720 vertical pixels which provides superior picture quality than analogue TV broadcasts.
