Some FAQ about HDTV:
How does HDTV work?
HDTV gives viewers vivid clear high-resolution images integrated with Dolby Digital 5.1 channel surround sound - creating a truly new viewing experience never seen before on domestic television sets. HDTV reproduces cinema-quality viewing by digitising TV programming, allowing it to be transmitted and received in the same way that a DVD player can reproduce films with cinema-screen special effects.
Why is HDTV better?
Better Quality Picture: Programmes that are filmed in HD offer a far superior picture quality, with vivid rich colours, razor-sharp images and greater levels of detail. To understand how this is achieved it is worth understanding where we are now. At present, all television images are made up of pixels going across the screen and scan lines going down. Currently British TV is transmitted using a format called PAL. A PAL picture displays 576 visible rows of pixels on the screen and these are interlaced. This means the whole picture is not displayed in one screen but instead all the odd rows are shown first then all the even rows. That means that the complete picture is only created after every second frame. HDTV’s picture boosts the vertical lines (lines the TV screen is composed of) from the standard 576 to 1080 - nearly doubling the amount of lines on-screen. The result is a picture which can be up to six times as sharp as standard TV. To truly receive the full impact, programmes need to be broadcasted in this format and the viewer needs to have receive the programme via a HDTV set (or HDTV-enabled set).
What else is better about HDTV?
Better Screen Size: Most televisions in homes today were manufactured in a 4 by 3 aspect ratio. All HDTV signals are sent in a 16 by 9 aspect ratio, mimicking the wide scope of cinema-released films. This gives the viewer a fuller picture as it works in a similar way to your eye, and is therefore a more compelling visual experience. Currently most new television screens have a 16:9 screen.
