Amateurs typically use the same standards as mainstream digital TV broadcasts: DVB-S (satellite) and DVB-T (terrestrial).

In the context of DATV on the ISS, "Ham Video" refers to the on-board transmitter, and "Ham TV" designates the video downlink combined with a voice uplink for two-way contacts.

Recent digital satellite television standards, such as DVB-S2 and H.264, can transmit HD video.

By contrast, ISS DATV uses DVB-S and MPEG-2 (which were designed around 1995) and a low bitrate.

Since May 2015 amateur radio operators can receive digital video directly from the International Space Station (ISS), at considerably higher quality than with earlier modes such as slow-scan TV.
