Latest HDTV News: Updated


Britain is to broadcast high definition programming on its free-to-air digital TV service by 2012, in time for the Olympics, under a plan to upgrade the technology by the media regulator.

Ofcom had already signalled its intentions to launch the service on the Freeview platform and on Thursday set out its plans after consulting with the major broadcasters.

Under the system, viewers with the correct equipment should be able to receive up to four new high-definition channels as digital switchover is completed by 2012, with three appearing in certain regions from 2009.

One of the slots will be used by the BBC Trust and the other three slots will be awarded to commercial public service broadcasters after a bidding process. Those bidding could include ITV, Channel 4 and Channel 5.

Ofcom said the applications would be judged on their efficient use of spectrum, the contribution to public service broadcasting and a contribution to the range and diversity of TV.

The transition to HDTV has been called a landmark move for the industry, similar to the shift from black and white to colour, and terrestrial broadcasters want to be able to compete with the sharply improved TV picture offered by pay-TV firms BSkyB and Virgin Media.

The regulator expects the plan to also benefit the economy, as it will make better use of the valuable spectrum reserved for broadcasting.



High Definition TV is a revolution in picture quality, with intense colour, clarity and definition.

HDTV is avaialable, with many broadcasters, many already filming some programmes in High Definition format. Sky started HD broadcasts in 2006 while some Hollywood movie studios have already committed to producing many movies on HD DVD. You will need an HDTV receiver or HD DVD player, but, most importantly, you will need a High Definition compatible TV to enjoy the visual benefits.

So what is HDTV?

HDTV is a digital broadcast system that delivers picture quality vastly superior to current broadcasts. The improvement in clarity, depth and sharpness of screen images is instantly visible.

The current TV broadcast system in the UK (PAL) delivers 576 active lines of interlaced picture information. HDTV provides an average of eight times more data on a display screen than a standard broadcast, thanks to the increased picture resolution.

There are three HDTV standards:2398_001

720p - progressively scanned 720 line picture

1080i - interlaced 1080 line picture

1080p - progressively scanned 1080 line picture

Buying an HD Ready TV now means your TV will be able to display the higher resolution HDTV when it becomes available. In the meantime you can make the most of the product's high specifications to get the best possible results from current broadcasts.

HD1080p

HD1080p

HD 1080p offers you very high resolution to generate it's picture. The 'p' stands for 'progressive scan', which scans all the lines at once to add stability & smoothness to fast-moving images. This makes 1080p TV's excellent for sport broadcast & games.


Integrated Digital Tuner / Freeview

Integrated Digital Tuner / Freeview

Having an integrated Digital Freeview Tuner means that your TV has a built in receiver that will give you access to many more channels without the need to have any additional hardware, such as a Freeview box. In 2007, the government will begin switching UK broadcasting to digital, so if your TV doesn’t have an integrated digital tuner feature you wont be able to view any channel without buying the additional hardware.


HDMI Sockets

HDMI Sockets

Your HDMI socket provides a connection point on your TV that is able to deliver a high definition picture. Quite simply, the more HDMI sockets that you have on your BRAVIA LCD TV, the more components you are able to link up to for HD picture quality, for instance, a Blu-ray player, your camcorder and your gaming console. Having the socket located in the front of the TV means that you no longer have to get into awkward positions or move the unit in order to gain access to the connection point, great if you’re viewing your photos on your TV via your digital camera. The X3500 has 3 – 2 to the rear and 1 on the side.


MotionFlow + 100HZ

MotionFlow + 100HZ

Conventional LCD televisions show 50 pictures (frames) per second (50Hz). Sony’s unique MotionFlow +100Hz HFR System doubles the pictures shown to 100 per second (100Hz). It does this by intelligently manufacturing the additional frames instead of simply repeating them. The result is smooth, judder free, natural motion. Ideal for watching action films, sports and gaming.


S Force Front Surround / Dolby Digital

S Force Front Surround / Dolby Digital

Unique surround sound technology that gives you 5.1 channel virtual surround sound from just 2 speakers. Using precise variations in timing and volume projection S-Force fools the brain into thinking the sound is coming from different directions.
This gives your BRAVIA LCD TV enhanced sound quality and the impression of 5.1 channel virtual surround sound without the need for extra speakers.


Live Colour Creation

Live Colour Creation

Live Colour Creation is a backlight system which produces a wider colour gamut, seen particularly with the red and green areas of the spectrum. So your TV picture will have more lifelike and natural colours with no smudging or dulling of the image.


BRAVIA Engine PRO

BRAVIA Engine PRO

This technology gives you greater definition & ensures that you’ll see every detail.

  • It reduces colour distortion by decreasing ‘cross colour’, ‘dot crawl’ and ‘moire’ the sort of distortion that you get on patterns such as a checked shirt. It cleans up the haze that you often see around lettering such as titles or text so that they appear perfectly sharp on screen.

  • It enhances specific areas of low contrast within the image giving an overall crisp picture.

  • It smoothes the motion, preventing jagged edges and bleeding colours on fast moving objects, ideal for sports & action sequences.

  • Matches colours. Exact colour reproduction ensures the final image is reproduced exactly as the original source intended meaning that you see incredibly natural colours.

  • It delivers enhanced digital reality creation, which in effect quadruples the number of pixels in any image source, which makes the image even sharper. When the entire process is finished it resembles the picture with more detail than ever before.


Dynamic Contrast

Dynamic Contrast

Contrast ratio is improved and all shades between the brightest white and the darkest blacks are maintained, so the picture has more depth and detail. This is achieved as the backlight brightness adjusts according to the brightness of the scene. Sony’s unique dynamic contrast system features ACE (advanced contrast enhancer) which ensures all of the subtle shades of grey are maintained.



24P True Cinema

24P True Cinema

'24p True Cinema' mode, is a perfect match for movies. Film is shot at 24 frames per second, but UK televisions operate at 25 frames per second. This means that when you watch a movie on DVD, you are seeing it sped up by 4 per cent. '24p True Cinema' enables the panel to display films at their intended 24fps (frames per second).


X.V. Colour

X.V. Colour

X.V colour offers a colour palette of 100% of the colour spectrum giving more depth, detail and natural images and is closer to the colour spectrum seen by the human eye.


BRAVIA Theatre Sync

BRAVIA Theatre Sync

A one touch control over your whole Home theatre set up. Simply press the Theatre button on the TV’s remote control, the TV’s sound turns off & the picture settings configure automatically to an optimal movie watching mode. BRAVIA Theatre Sync cuts out the complexity so that you can concentrate on enjoying your movie.


VESA Hole Spacing

VESA Hole Spacing

VESA-Standard or Video Electronics Standards Association is a perfect template for hole spacing (screw holes) in flat screens. So providing your wall bracket is also VESA standard, hanging your TV on the wall, for example, is a simple process without the frustration of drilling the holes incorrectly and in the wrong place.


LED Backlight

LED Backlight

Only available on the premium X70" BRAVIA, the slim TRILUMINOUS LED backlight attains superior colour reproduction that is simply unmatched by other current backlights. Because LED’s emit purer reds & greens, they can be used to produce a brighter & more uniform white light that captures the true colours of the source.
