摘要

You may know that the standard for broadcast television video since the digital conversion a few years ago is known as ATSC, which stands for Advanced Television Systems Committee, the name of the body responsible for formulating the standard (the analog standard in the U.S. and Canada was NTSC, for National Television Systems Committee). Almost as soon as the FCC and international standards bodies approved the initial ATSC standard, work began on a successor. ATSC 2.0 was nearly dead before it got off the ground, though. The rapid pace of technology meant that a standard focused on advanced video compression, targeted advertising, better programming guides, and video on demand was outpaced by the marketplace before it could be formulated. That meant work quickly focused on ATSC 3.0, and that new standard will be coming to your TV in the next two years. So, get ready and we'll have a look at what that means.
