ATSC was formed in 1982 by the member organizations of the Joint Committee on InterSociety Coordination (JCIC): the Electronic Industries Association (EIA), the Institute of Electrical and Electronic Engineers (IEEE), the National Association of Broadcasters (NAB), the National Cable Telecommunications Association (NCTA), and the Society of Motion Picture and Television Engineers (SMPTE). Currently, there are approximately 150 members representing the broadcast, broadcast equipment, motion picture, consumer electronics, computer, cable, satellite, and semiconductor industries.
ATSC Digital TV Standards include digital high definition television (HDTV), standard definition television (SDTV), data broadcasting, multichannel surround-sound audio, and satellite direct-to-home broadcasting.
ATSC 3.0 standard is designed to deliver improvements in performance, functionality and efficiency so substantial to warrant implementation of a non-backwards-compatible system. The IP-based standard, with its higher throughput capacity, can deliver:
- Enhanced quality for audio and video services
- Robust mobile reception on a wide range of devices
- Improved spectrum efficiency
- AEA(Advanced Emergency informAtion)
- Personalization features
- Interactive capabilities
What people expect for TV in 5G will be interactive service in high quality audio and video. In terms of interactive service in ATSC 3.0, below diagram shows how to combine application with broadcast stream together that is already implemented in common Smart TV on the market that means the partners can implement all the necessary things easily in HTML5.

Following diagram shows how ATSC 3.0 AEA(Advanced Emergency informAtion) system enables broadcasters to deliver timely, in-depth emergency related information to their viewers, which can strengthen the connection between the audience and the station and provide critical information in times of need.
