Car dvd player 101-what is ATSC-HDTV-DTV-ANALOG

In this episode of Car DVD player 101, we are going to have a discussion over the question: what is ATSC? How does it work in a car DVD player.

ATSC stands for "Advanced Television Systems Committee." Actually it is a set of standards on how sound and video are encoded and transmitted ,which now includes 18 commonly used digital formats.
the United States is the first country in North America to quit analog broadcasting signal which provides a poor quality of picture and sound compared with even the lowest quality standard of ATSC. Canada and Mexico are now considering make a sweeping switch from analog signals to ATSC.
HDTV is the top level of ATSC standards ,but whether you could see a high-definition picture and hear a clear sound depends on two factors. First the station that you followed should be broadcasting a high-definition signal that meet ATSC standards, secondly you have to have the right device to receive and view it which means that you should get a overall picture on the equipment that you shelled out money for.
In our next topic we are going to learn more about how HDTV works.
