What is digital TV?
Digital TV is the standard of broadcasting, which includes the use of digital signals instead of analog signals, traditionally used with television broadcasting. Although there is some confusion on this topic, the presence of a digital signal does not mean that there is a high -resolution television. Both are very different. Digital signals allow high resolution but are not guaranteed. The advantage of digital television is that there is no signal degradation, which means that the image can be sent more clearly and the sound will also be better quality.
To really understand what digital TV is, it is necessary to understand the difference between analog and digital signals. An analog signal is a wool that is sent or recorded in its original form. It is like a cast made from a track that is transported from one place to another. The form of cast will never change during transport. The digital signal breaks the signal and assigns its numbers for reconstruction at the finish. In some Ways it's like a puzzle that is dismantledAfter the numbers of each piece, then assembled in a different place.
For individuals to get digital television income, they must do one of two things. It must either change its analog TV into a digital set capable of receiving signals or to obtain a box that can translate the signal from digital to analog. Digital television boxes are likely to be cheaper, but improving the quality of the signal will not be as big as those who have digital TVs.
For those who receive cable or satellite services, there is no need to worry about digital television services. In most cases, they have received a digital signal from their cable provider. Therefore, the only people who would be influenced by the transition to digital television are those who receive a signal for their TVs in the air using a traditional antenna. Since the choice of this option is individuals with lower income, they are woolingDA USA provided grants that will partly pay for the population boxes for the inhabitants.
As soon as the transition occurs, the benefits will be observed in the quality of the image and sound. The so -called ghosts and snow, which sometimes a morbian analog television will be a matter of the past. Digital TV channels will come very clearly. The sound will also be sharp, although it can take a decent additional sound system for most people to notice the difference. Built -in TV speakers usually do not have enough quality to actually reflect the difference in digital sound.
