A Product for Future: Digital Television

Digital television can be defined as a system of telecommunication that receives moving pictures and sound by digital signals. The most recent development in television industry, digital television has lot of advantages and scores over traditional or analog television in a big way.



The biggest advantage that digital television has is the fact that it consumes very little bandwidth space, thereby, ensuring that digital broadcasters provide more digital channels as well as high-definition digital service or non-digital channels or non-television services. Digital television also provides better picture and audio quality.



However, what should not be forgotten is the fact that though digital tv has several advantages, it has some drawbacks as well. For example, due to limitations of bandwidth and compression of algorithms such as MPEG-2, there are certain defects in picture quality which is not there in analog television.



Then again, comparatively, a compressed digital image, vis-à-vis the original program source, like a 35 mm motion-picture film print, will display certain defects like quantization noise, colour mismatch or blockiness, whenever high-speed motion is depicted or hazy picture.



Thus, it becomes amply clear that digital television has quite a few features that transform television viewing into absolute joy. Though it also must be understood that because of being a recent invention there are certain short comings which no doubt will be eradicated with time.
