What is ATSC Digital?

ATSC Digital is the current set of standards for broadcasting television in the United States. In June 2009 it replaced previous standards, NTSC. The most important introductions are the support of wide -angle screen formats, high -resolution images and full of digital space sound. Standards In this context, the technology used, not for editorial content or quality of programming, relates. Accepting a single set of standards has increased a potential audience because people could be sure that all sets can cope with all broadcasts. Programmers also facilitated selling programming for repetition in different networks. It was the number of lines on the screen, the speed at which they were restored, and the way in which the material from Filmudo TV was transferred. Standards also obscured the system used to coded color information and the way in which sound and video information was arranged at available broadcast frequencies.

AtSC digital standards have been developed in readiness to replace analog television broadcasts by digital broadcasting. Most of the new standards do not absorb nonsensically by broadcasting in digital format. Instead, they deal with questions raised by a larger range of options that are open for broadcasting, because digital broadcasting is more efficient when transferring information. These standards also apply to high -resolution broadcasts that are simply standards that exceed the set resolution.

One of the key differences with ATSC digital standards is that there is support for a much wider range of images and shapes. These include both wide -angle screens and 4: 3 ratio pictures. There is usually support for progressive and interlaced scanning and two or more different images in each of these resolutions. Standards are more of a picture resolution rather than the physical size of the TV screen. It's because two screensDifferent sizes can show the same number of pixels, while the magnification of the size is greater on the pixels than the picture, which is more detailed.

AtSC digital standards also add Dolby Digital AC-3 as the main supported sound format. This format allows broadcasting full spatial sound known as format 5.1. NTSC standards only had stereo sound signals.

It is important to realize that virtually all TVs, however old, should be able to display images broadcast using ATSC digital standards. There is no inherent technical reason why no air can pick up the ATSC signal. However, either the TV itself will be needed or the set-top boxcodecodes information in the ATSC signal.
