ATSC 2.0 was long overdue, with MPEG-4/AVC codecs being deployed almost exclusively in all new systems on satellite and Cable. If the fact that the HDTV which needed to be carried also had to use MPEG-2 was not enough, the Mobile TV encoded in any format ( MPEG-4, VC-1 or others) could not be carried on the ATSC systems as it did not allow the Hierarchical modulation available in CoFDM based systems.
Hence ATSC 2.0 is a brave initiatve to bring the good old standard in tune
with the new services which it nneds to carry. ATSC-M should lead to a implementations in the next year. http://www.mobiletvhome.com
