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.
