Plenty of ATSC .0 Gear on the NAB Show Floor

LAS VEGAS-It s no secret that the first version of the ATSC broadcasting standard, now called ATSC 1.0, was not universally loved when television stations switched to digital broadcasting more than a decade ago. The first commercial broadcasts of ATSC 1.0 began in 1998, and that essentially engraved the standard in stone-little, if anything has changed since.

Sure, digital HD broadcasting looks good when compared to analog standard-definition NTSC broadcasts, but ATSC 1.0 s MPEG-2 encoding standard was old by 2004, and its 8VSB modulation is power-efficient but reception-fragile, especially if you are mobile or trying to use an indoor antenna.

That s why there is so much interest in the ATSC 3.0 standard, which has leapfrogged over ATSC 2.0 (which is semi-compatible with ATSC 1.0) and is capturing the attention of manufacturers and broadcasters alike.

At the 2017 NAB Show, there will be several demonstrations of ATSC 3.0 technology-including over-the-air broadcasting of 4K video from Las Vegas TV station KLSV-and products for ATSC 3.0 will be in locations spanning the exhibition floor. These products include not only the expected exciters, transmitters and test gear, but also antennas with special features for ATSC 3.0 broadcasting. However, the real surprise may be the new receivers with integrated ATSC 3.0 tuners.
