ATSC 3.0

ATSC 3.0 introduces a new suite of standards adopting DASH and internet technologies.

ATSC 3.0 Overview

The American Television Standards Committee has released a suite of standards defining an ATSC3.0 digital television system. The DASH and Internet based technologies adopted for the ATSC 3.0 system represent a radical break from the MPEG-2 based ATSC 1.0 standard in order to provide a technological leap forward.

Improvements over ATSC 1.0 delivered by the ATSC 3.0 system include:

• Support for HD and 4K UHD video resolutions over the air
• Immersive audio including Dolby AC-4
• Higher bandwidth in a 6Mhz slot offering more and/or higher quality services
• COFDM modulation giving better coverage for built-up areas and mobile receivers
• Advanced Emergency Alerting
• Delivery of Non-Real Time (NRT) file-based content alongside AV to provide targeted advertising and other enhanced viewing experiences
• Integration with Internet-based AV, file and application delivery to provide an enhanced range of services to the viewer 

S&T provides a range of products that support generation and monitoring of ATSC3.0 content for test, trials and production environments:

• ATCaster, a server-based product that generates ATSC 3.0 streams for broadcast. 
• ATRunner, a lightweight ATSC3.0 stream generator for testing.
• ATMonitor, a server-based monitoring tool that analyses ATSC 3.0 streams.
