ATSC 3.0 and DVB-T2

Some time ago, I sent an email to the ATSC asking them why they didn't combine their ATSC 3.0 efforts with DVB-T2 (they didn't answer).

It seems to me there are more similarities than differences between ATSC 3.0 and DVB-T2 and combining them would be logical, anyone have any behind the scenes info as to why this didn't happen?

DVB-T2 was standardized in 2009. ATSC 3.0 was standardized in pieces starting around 2016. Naturally, the two couldn't be combined since they were created at different times.

They didn't answer, because (like Trip says) DVB is an older standard. Other than being based on COFDM, there are nothing similar.
 
I was thinking more along the lines of audio and video codecs and datacast formats, I guess we'll have to wait for ATSC 4.0 and DVB-T3 to try to arrange "harmonization" of the 2 standards.

It affects stations from adding Digital Sub Chanhels that aren't available in a certain city yet and low power stations usly don't get added to Cable providers.
 
Honestly the U.S. should have gone with ISDB-Tb instead of reinventing the wheel with ATSC 1.0. Japan's digital TV standard seemed to be the natural successor to analog NTSC. Cord cutting would have been more widespread without the digital cliff effect discouraging the average viewer by using 1seg instead.
 
It seems the countries who switch to Japanese ISDB-Tb (Japan, Philippines, Central and South America except for Colombia and Panama) the signal tends to do well with little flickering or choppy verses DVB and ATSC version. I don’t know about China or Cuba dtv version DTMB.
