As 'Asia's world city', Hong Kong may have more fizz than any other. But does your life ever feel starved of colour? If so, you may care to consider the vision offered by high-definition television (HDTV). HDTV signals are transmitted in a very high frequency band, delivering a wider and finer picture. What you register is as clear and unflattering as what you see through your eyes when you look around your office. Another plus is the lack of 'ghosts' that bedevil large LCD and plasma TVs as a tail of the image moving across the screen. HDTV has been in the air for almost as long as X-Rayspecs and is forever flickering in and out of the headlines. 'Although it's been available for several years, HDTV has only recently moved toward centre stage,' according to the Boston Herald, which claims that more and more sports fans are embracing it because the experience of watching a game via HDTV 'is almost as good as being there'. Last month, for the first time, live SMS chatting and voting were featured in high-definition interactive TV across America. Soon, HDTV will be available on your mobile, supposedly. 'HDTV is ready for prime time,' the evangelists stress. But they have been saying that forever. Two broad reasons for the invention's teething trouble come to mind. The first is that some of us already feel guilty about the amount of time we spend glued to movies rather than spreadsheets or taking exercise. The second is that we have 'adoption fatigue' and just cannot be bothered to get to grips with new TV technology when the current stuff is tricky enough. Robert Adler, the retired Zenith engineer who helped invent the remote control more than 50 years ago, recently grumbled that you need a pilot's licence to operate a remote control these days. But viewers who figure it out are happy. The typical female convert says: 'I used to really envy [insert name of movie siren] but then, thanks to HDTV, I discovered that she is actually repulsive. Who would have guessed that she has blotches, zits and chicken wattle skin under her chin? Thank you, HDTV, for the kick-ass boost to my self-esteem.' The typical male convert portrays HDTV as a step towards technical perfection: 'Before I discovered HDTV I thought my set offered a decent picture. Now I realise how I've been cheated all these years - the picture is as grainy as a bowl of granola viewed through a webcam on a 56kbps connection.' Nobody, however, has a good word to say about the price. HDTVs still cost about twice as much as similarly sized analogue sets. Worse, to handle the increased resolution, you may need to upgrade your video recorder or DVD burner. Worse still, even if you can afford to splash out on HDTV and its trappings, what exactly will you watch? Before you take the plunge and invest in a multi-megabuck system, check how much content is available. HDTV is a classic chicken-and-egg problem - neither TV companies nor consumers appear willing to commit to it first. HDTV evidently needs to improve its image and become as seductive as DVD. But the question is how can anyone publicise it effectively? The standard ad zooms in on a picture of an HDTV set while the voiceover raves about the pin-sharp picture that utterly fails to come across on the low-resolution box owned by the viewer. If seeing is believing, potential customers will have to leave their armchairs and visit their local electronics store. Although HDTV appeals to me, I do not find it irresistible. I plan to hang on to my fuzzy but trusty vintage TV until it becomes unwatchable and/or uneconomical to repair. When I want a razor-sharp image of the world in stereo vision, I'll just rely on my failing eyes.
