Amateur radio encompasses a wide variety of modes and innovation. One of these fascinating areas is amateur television which covers all aspects of video production, editing, transmission and reception of television. It has often been at the forefront of the technology developments. 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.
