On March 28, 2016, the Bootstrap component of ATSC 3.0 (System Discovery and Signalling) was upgraded from candidate standard to finalized standard.[1]
Finalized stadards:
- A/321: System Discovery and Signalling
Candidate standards:
- A/300: ATSC 3.0[2]
- A/322: Physical Layer Download Standard
- A/323: Physical Layer Upload Standard
- A/330: Link Layer Protocol
- A/331: Signaling, Delivery, Synchronization, and Error Protection
- A/332: Service Announcement

- A/342: Audio Standard[5]
- A/343: Captions and Subtitles
- A/344: Run-time Standard (apps for advanced televisions)
Recently amended standards:
- the main ATSC standard has been recently amended to support Enhanced ATSC; this transmission mode is backwardly compatible, but provides much better error correction.
ATSC-M/H for mobile TV is still pending as of February 2009, though it is known that it will use MPEG-4 instead of MPEG-2.
