Nowadays, on the global market, we can find everything that we want, from the lowest services to the highest products. Indeed, the well-known communication space is so developed that we are able to connect easily with people and friends all across the world. This is what is tendered by the newest approved technology. As a matter of fact, one of these telecommunications devices is the television, something used since nearly eighty five years. Moreover, this sphere is enduring one splendid revolution, from analogue to digital broadcasting. The benefits of it are exposed and examined in the below sections.
First of all, it is good to begin with some details and common information. The first TV transmitting was in the summer of 1931, which was one example from one very eminent scientist, Epsom Derby. Year after that was shown the ultra short wave television, which also was the beginning of faster developing in this sphere. For years we used first black and white TV, after that picture with extended colour gamma with three more colours red, green and blue. By the way, the mixing between those three components was able to recreate the all colour gamma. Interesting fact is that the broadcasting was by air and our receivers were the antennas.
In the end of eighties and the beginning of the nineties, one thing changed everything: the cable television. In this progress on the global market have appeared a lot of the cable holders. Parallel with that the digital communication also starts its evaluation, called internet. However, then in the TV’s transmitting was used the analogue modulation, distributing waves to the terminal customers.
After the new century enters in its commencement, the satellites start to integrate the new digital technology in broadcasting of TV signal. Few years after that, the cable operators also started to force the digital signal. Precisely for that reason, nowadays we are able to choose between satellite and terrestrial television.
Why the DTV is better than the analogue? That is a question, which can be answered briefly or extensively, but the main thing is that in the end we will approach the same result. Firstly, the analogue channel occupies six times more bandwidth than the digital one; hence we can save a lot of space with the new technology as time to be distributed. Another benefit is the quality that can be offered by the high definition signals, one of the newest type digital televisions. This is really one amazing boom in the TV’s sphere, because high contrast, brightness, sound and picture are accomplished. In addition, now we are able to watch even full HD TV, which means we can see 1920 on 1080 pixels on our screens.
