The next generation of TV technology
The next generation of TV technology
As we all know HDTV stands for High Definition Television, but what is HDTV?
HDTV sets new standards in your television viewing experience by offering exceptional picture quality. Simply put, HDTV is the inevitable upgrade from today's analogue system.
HDTV uses digital technology to transmit an enormous amount of information in the same amount of space as used for standard 'analogue' TV. A traditional TV would use 576 vertical lines to produce images on screen. When you compare that to the 1080 produced on an HDTV you will see a world of difference.

What is the difference between 720p and 1080i?
720p stands for resolution of 1280x720 pixels and the magic little 'p' means that the picture is in a progressive scan format. The other HDTV resolution 1080i means 1920x1080 pixels and the magic little 'i' means that the picture is in an interlaced format.
An interlaced picture means the TV shows every odd horizontal line in the scan then every even line in the second scan. This means the complete screen is shown every other scan. Don't worry, this all happens so fast your eyes cannot detect it.
Progressive scan is based on all the horizontal lines being shown on the screen at one time giving a smoother image.
It is generally believed that a progressively scanned picture is more suited to fast moving images such as sports, whilst an interlaced format is more suitable for slower images such as films and documentaries.

How can I receive HDTV?
SKY has announced that they will be launching HD transmissions in early 2006. For this you will need to purchase a decoder and if not already installed, a satellite receiver dish will also be needed. The BBC has also committed to broadcasting in HD as soon as possible via the terrestrial broadcasts (DVB-T).

Are all digital TVs HD?
No. Digital TVs, generally referred to as IDTV are capable of receiving 'standard' digital signals, and whilst noticeably different to an analogue signal it is not High Definition. Some HD-ready sets are however IDTV and capable of picking up the digital signal currently broadcast on 'Freeview'. HD-ready sets can also receive Freeview or Sky digital by the use of a set top box.
In short an HDTV does all your existing TV does and more.

What are HDMI, DVi and HDCP?
Both High Definition Media Interface (HDMI) and Digital Video Interface (DVi) are connection types used to connect your source, be it set top box, Blu-Ray DVD, HD DVD etc, to your HDTV. Both HDMI and DVi offer high-bandwidth connectivity capable of carrying the HD signal to the TV. Already widely used HDCP (High-bandwidth Digital Content Protocol) is the copyright protection that helps to protect against unauthorised recording of HD content. Both HDMI and DVi support HDCP.

I have seen DLP, what is it?
Digital Light Processor or DLP is a device which by the use of millions of little mirrors, one for each pixel, creates a very high quality projected image. DLP is widely used in rear projection or front projection units and yes, they can be HD-ready.
