The LG 4K UHD HDR Smart LED TV - 60" Class (59.9" Diag), Model # 60 UJ6300 is an ATSC 1.0 chip. When stations are repacked to new channels as part of the FCC’s spectrum auction, they will also switch from today’s ATSC 1.0 system to the new ATSC 3.0 system. ATSC 2.0, an improved interactive standard, would not have required significant updates to the existing ATSC 1.0 broadcast infrastructure, however, ATSC 2.0 has been largely overtaken by the new focus on ATSC 3.0. ATSC 2.0 had been looking to incorporate some set top box style features into broadcast TV such as streaming Internet services, video on demand, and interactivity while also giving broadcasters and advertisers some capabilities like audience measurement and targeted advertising. You won’t see ATSC 2.0 released to the public, however. Given where technology has evolved, ATSC 2.0 will be leapfrogged by ATSC 3.0. Many of the technologies developed for ATSC 2.0 are expected to be supported in the new ATSC 3.0 system. While ATSC 2.0 was envisioned to be backwards compatible with ATSC 1.0, ATSC 3.0 will be a completely new standard and incompatible with current broadcast systems. The initial target date for ATSC 3.0 was to be by the end of the second quarter of 2017, however, the Federal Communications Commission only recently voted unanimously to allow broadcasters to voluntarily deploy ATSC 3.0 on February 23, 2017 in response to an April, 13, 2016, petition by broadcast and consumer electronics lobbies that broadcasters be allowed to adopt and deploy ATSC 3.0 on a voluntary and market-driven basis. The petition explains how the industry plans to deploy Next-Gen TV in parallel with the current ATSC 1.0 standard to address compatibility issues. Under this approach, a temporary “host” broadcaster in a market would agree to simulcast on its airwaves the other DTV signals of those stations broadcasting with ATSC 3.0. The “host” station’s programming would reciprocally be carried as a programming stream by one of the stations deploying the Next-Gen TV standard.FCC Chairman Ajit Pai is hoping to have a final order by the end of the year "so that American broadcasters can deliver to our nation's citizens even more of the marvels of the digital age."...^IFV
