  3. 3. What is ATSC 3.0? …ATSC 3.0 is a suite of voluntary technical Standards and Recommended Practices that is fundamentally different from predecessor ATSC systems and is therefore largely incompatible with them. Source: ATSC A/300:2017 - ATSC 3.0 System -
  4. 4. That sounds scary… Diffusion of Innovation - Everett Rogers ….four main elements influence the spread of a new idea: Source: Wikipedia • the innovation itself • communication channels • time • and a social system
  5. 5. …I’ve heard this before! This divergence from earlier design is intended to allow substantial improvements in performance, functionality and efficiency sufficient to warrant implementation of a 
 non-backwards-compatible system. Source: ATSC A/300:2017 - ATSC 3.0 System -

  7. 7. What’s the value proposition? Source: ATSC A/300:2017 - ATSC 3.0 System - With higher capacity to deliver Ultra High-Definition services, robust reception on a wide range of devices, improved efficiency, IP transport, advanced emergency alerting, personalization features and interactive capability, the ATSC 3.0 Standard provides much more capability than previous generations of terrestrial broadcasting.
  8. 8. …That sounds incredibly complex Image Source: ATSC A/300:2017 - ATSC 3.0 System - Conceptual Development of ATSC 3.0 started after 1.0 was released with the Grand Alliance. Rethinking the fundamentals of RF Spectrum Allocation and Utilization built on IP.
