Does the ATLANTA RT0572 decoder allow receiving HD TV?

Hello,
No, this decoder does not allow you to receive HD channels.
Here is a list of devices compatible with HD channels http://www.tvnt.net/forum/liste-des-adaptateurs-tnt-mpeg-4-hd-t11703.html#p132704

Thank you for the information because I thought I could at least receive TF1HD, FR2HD, and M6HD.

It is very simple, a DTT adapter must be equipped with a "MPEG 4" tuner to tune into the 6 new HD TV channels. All new HD DTT adapters sold since December 1, 2012, are equipped with one, as the sale of MPEG 2 (SD) is prohibited...
