4k OTA: Revolutionizing TV Broadcasting

Very soon, you will be streaming your favorite TV shows in 4K crisp quality, and that is not even the best part. Now, imagine getting double the punch of your current Dolby surround sound as you watch movies and TV shows in 4K. Soon 1080i or 720p will be a thing of the past once the ATSC 3.0 4K over the air is fully up and running.


Motion picture and sound has evolved a great deal over the past few years. The goal has always been to improve what is already there while searching for better and greater ways to broadcast content. The Advanced Television Systems Committee (ATSC) consists of tech and telecom companies that dictate the quality of broadcast signals. Simply put, ATSC is the genius behind the transition from 720p to 1080p, 3D, and the 4K.

ATSC 3.0 Standard

Nerd Alert: The ATSC 3.0 is a framework designed to lay the path for the coming of 4K viewing possibilities. In the near future, you will be able to stream videos in 3840 x 2160 resolution on your television and even mobile devices. The ATSC is improving the standards of their system discovery and signaling architecture. Head over to atsc.org for more details on the exciting world of broadcasting standards (note: sarcasm).


However, for this transition to be smooth, a few things need to be done. Currently, 1080p and 720p streaming standards are the norms. Content such as movies and TV shows are shot on the 24fps format and viewed on 1080 or 720. Only a select number of people will likely appreciate the crispness and clarity of 4K, many cord-cutters are already happy with current HD broadcasts. Nevertheless, the ATSC 3.0 is giving us a glimpse of a future where Ultra HD, wide color gamut and high dynamic range (HDR) will be the norm, and the reality is unraveling fast.

As video gets a complete face-lift, audio will not be left behind either. Part of the ATSC 3.0 plan is to boost audio to match the visual capabilities they envision. This means a great leap from the current Dolby technology to a more advanced Dolby AC-4 and MPEG-H. In addition, you will be able to customize the sound quality to suit your home devices and personal preferences. The ATSC is also working on a multi-audio platform where several audio devices can be connected to a single source. This means that you will be able to watch a movie on your screen and stream the sound on your home theater, tablet, or Bluetooth headphones.

With increasing demand for better audio-visual features, the ATSC 3.0, 4k over the air will be here sooner than expected.
