Digital, HD and 4K TV FAQ
What are the advantages of High-Definition TV (HDTV)?
A high-definition (HD) signal enhances both the picture and the sound of programs so that they are crisper and more detailed than ever before.
Clarity: HD image resolution is more than five times what was previously available. This means that there are more pixels of colour, providing a wider range of hues and a never-before-seen level of fine detail.
Widescreen: HDTV is shown in a 16:9 ratio as opposed to the 4:3 ratio of older TVs. This gives you a more dynamic view, like that of a movie-theatre screen, and lets you see what was cut off the edges when movies were modified to fit the narrower ratio.
Sound: HDTV programming is able to provide Dolby Digital 5.1 surround sound so that it sounds like the action is happening all around you.
