BANGALORE, INDIA: Today, every one is going crazy over high-definition technology and the demand for enhanced digital picture quality and visual feel has prompted industry experts to look beyond the traditional analog display options.

Emergence of HDMI and DVI has given people the option to enjoy high quality digital display minus any distortion. These technologies have obliterated the demand for analog options such as S-Video and Component. The move towards more options may see a complete exit of analog displays in the near future. In this story we show what makes digital displays such a rave and what's the future of analog displays.

Why digital?
Digital signal transfer is assumed to be error free, while analog signals are always subject to some sort of degradation in signal quality and information loss. This is true to a large extent but when you consider the usage scenario, there's no reason why any predictable degradation of an analog component video signal should occur for a small distance; for example, even for a home theater installation, it doesn't present a challenge for analog cabling if built to professional standards.

Hence there is no reason why there would be information loss or any substantial degradation which would be noticeable to the naked eye. It's also not correct to suppose that digital signal handling is always error free. Both HDMI and DVI signals aren't subject to error correction; hence if information is lost, it's lost forever.
