Digital television is a technique of representation of the video and audio signal into digital form, i.e. as a sequence of binary digits. The digital video signal is inevitable for computer storage and servers, but also extremely effective for a true broadcast-quality signal. In broadcasting, terrestrial or satellite, digital technology has been gradually adopted since the late nineties and today, in many countries including Italy, has completely supplanted analog technology, with which the television had been going on for over fifty years. Numerous experiments until the early nineties had demonstrated that a high-definition signal in analogue format was impractical, though very attractive. For efficiency of storage and transmission, television services in high definition are much better delivered with digital technology. In this sense, high definition is only one of the possible formats offered by digital television, which supports a whole family of formats: SD, HD , 3D , and UHD1 UHD2 , as well as numerous other video formats available on the Internet.<\/p>\n","protected":false},"excerpt":{"rendered":"
