Many amateur stations are now transmitting digital pictures DATV using the DVB broadcast standards; and using video streaming technologies to exchange pictures with ATV operators around the world. Radio amateurs have been transmitting and receiving TV pictures for over 60 years. In most cases, simplified versions of the broadcast standards of the day have been used, perhaps tailored to a reduced bandwidth to fit within the amateur bands. Frequency modulation, as used for early commercial satellite TV transmissions, is still popular, in particular on 5. Digital television modes, as used for current commercial satellite TV transmissions, have proved to be very robust and efficient for amateur television transmissions. These transmissions can be received on a domestic satellite TV receiver—with an up-converter or down-converter for bands other than MHz—or a specialised receiver such as the MiniTiouner. Amateurs are currently experimenting with reduced bandwidth transmissions in bandwidths as low as 50kHz which can be decoded from weaker signals than the wider bandwidth transmissions. By far the most popular receive system is the MiniTiouner. The MiniTiouner hardware can be self-built or purchased as a pre-assembled unit. The MiniTiouner Hardware. The MiniTiouner covers MHz to MHz and so, with the addition of pre-amplifiers, it will receive on four amateur bands directly and it can be used with down-converters for the other bands. The MiniTiouner software is designed to run on a Windows 10 PC—although the current versions works satisfactorily with Windows 7.

ATV includes the study of building of such transmitters and receivers , and the study of radio propagation of signals travelling between transmitting and receiving stations. ATV is an extension of amateur radio. In North America , amateur radio bands that are suitable for a television signal wide enough to fit such a signal are higher in frequency than VHF broadcast TV. The lowest frequency ham band suitable for television transmission is 70 centimeters , which is between broadcast channels 13 and For more sensitive reception, some users may use a purposely-built ATV down-converter, which is a kind of set-top-box.

Some areas may only operate through a crossband repeater and very little simplex. However, the unavoidable processing delays caused by the temporal compression mean that DATV signals have a second or more of time lag, which can make real-time video conversations feel much less natural than the 'instantaneous' analogue system.
