What is Digital Television? | TV Guide Listings

Digital TelevisionDigital Television (DTV) is a digital and computerized method of transmitting sounds and pictures through television.  It is a great improvement from the old analog television methods as it can provide better quality in terms of picture and sound.Digital television converts sounds and images into computerized digital data, and delivers them to the receiver. When the data is transmitted, the receiver inputs the data together with the original picture and sound. Because it converts the data into smaller bits of information, it uses up less bandwidth space in the airwaves and therefore provides more space for more channels and features. Compressed data can be easily transmitted through airwaves as they are smaller compared to the original data. Because of this, many cable providers and television audiences are now switching to digital television broadcasts because they would not feel the need to delete channels to replace it with a better one.

This process takes longer time to transmit data but it provides a great improvement in the results as compared to analog television. The picture displayed through digital television comes out as more defined because a digital tuner blocks out any interference to the signal. Sound is also more precise as the digital tuner lessens the noise caused by interference. Clearing out any interference to the signals being transmitted to the receiver brings a very impressive display of picture and release of sound. Your digital viewing experience will not be the same without the digital tuner. This is one of the greatest advantages of digital television. When compared to analog television, there is a stark difference. This is why digital television is very impressive, and so far the best viewing option present. Analog television display pictures by firing a whole frame all at one time. Digital television, on the other hand, is different as it displays images in either an interlaced scan mode or progressive scan mode. These modes contribute greatly to delivering a smooth display of motion in the pictures.The features one can get from DTV may vary depending on what platform is used to receive digital broadcasts. Digital television may be offered through digital terrestrial, satellite, cable, or broadband. The differences of these offers may depend on the service provider but one thing they all have in common is that they can offer more than 40 television channels.Digital television also provides its viewers with a superior viewing experience by supplementing them with a wide array of additional features, including interactive services and bonus scenes. Additional features may be anything from subtitles, channel and program listings, games, or supplementary or behind the scenes footage. Users can even embed digital data into the television through an advanced computer system. Through these features, digital television becomes a very user friendly form of entertainment to viewers as they experience better quality and increased convenience in channel surfing. Viewers need not to randomly flick through channels, instead they can see what is next on air through a channel and program listing. Again, the features that a viewer can get may depend on the service provider that you will choose.
