HDTV Connections Explained

Component video (analogue) is capable of producing signals such as 720p, 1080i and 1080p, but digital connections such as DVI (video only) and HDMI (which can also include up to 8 channels of audio) give better results at the higher resolutions (up to 1080p). HDMI also includes both a video and audio signal in a single cable.

In order to receive a digital signal a HD TV must have either a HDMI (High Definition Multimedia Interface) or DVI (Digital Visual Interface).

HDMI appears to be the way forward for the HD TV manufacturers but a lot depends on what you wish to connect to your HD TV. For example, your DVD output may well be analogue (component video) and your set top box output digital (HDMI).

To comply to the HD TV standard all televisions must have either component video, DVI or HDMI inputs.

It is also worth noting that other inputs such as S-Video, composite video or VGA may well be useful depending on what legacy equipment you may wish to connect.
