Advanced Television Systems Committee standards

ATSC coexists with the DVB-T standard, and with ISDB-T. (America ATSC Africa Europe primarily DVB-T
and S America ISDB-T, (ISDB - Integrated Services Digital Broadcasting))
ATSC 3.0[edit]
ATSC 3.0 will provide even more services to the viewer and increased bandwidth efficiency and compression performance, which requires breaking backwards compatibility with the current version. ATSC 3.0 is expected to emerge within the next decade.[14]
On March 26, 2013, the Advanced Television Systems Committee announced a call for proposals for the ATSC 3.0 physical layer which states that the plan is for the system to support video with a resolution of 3840×2160 at 60 fps (UHDTV).[17][18][19][20]
In February of 2014, a channel-sharing trial began between Los Angeles television statons KLCS (a Public broadcaster) and KJLA, a commercial ethnic broadcaster, with support from the CTIA and approval of the Federal Communications Commission. The test involved multiplexing multiple HD and SD subchannels together, experimenting with both current MPEG-2 / H.262 and MPEG-4 AVC / H.264 video codecs. Ultimately, it has been decided that H.264 would not be considered for ATSC-3.0, but rather the newer MPEG-4 HEVC / H.265 codec would be used instead, with OFDM instead of 8VSB for modulation, allowing for 28 MBps or more of bandiwdth on a single 6-MHz channel[21][22][23][24][25]

Digital TV DVB-T2
What is DVB-T2? DVB-T2 is the world’s most advanced digital terrestrial television (DTT) system, offering more robustness, flexibility and at least 50% more efficiency than any other DTT system. It supports SD, HD, mobile TV, or any combination thereof.

SEVENTH SADC DIGITAL BROADCASTING MIGRATION
The 7th SADC Digital Broadcasting Migration Forum was attended by Delegates from ten (10) SADC Member States namely; Botswana, Kingdom of Lesotho, Malawi, Mozambique, Namibia, South Africa, Kingdom of Swaziland, United Republic of Tanzania, Zambia and Zimbabwe. The Forum was also attended by representatives from SADC Implementing Agencies including the Communications Regulators’ Association of Southern Africa (CRASA) and Southern Africa Broadcasting Association (SABA). Also in attendance to share their experience in the migration process were representatives from African Telecommunications Union (ATU), GSMA and Federal Communications Commission (FCC) of the Unites States of America.
. He iterated the commitment of Botswana to meet the timelines set by the International Telecommunication Union (ITU) for the Migration from Analogue to Digital Terrestrial Television (DTT).

......SA, FCC, ITU......hmmm
The world standards map helps put things in perspective; DVB-T2 is to be used in SA.
