MMSSTV stands for Makoto Mori (JE3HHT, creator) Slow Scan TV. It has been the defacto standard SSTV application for many years. Under the pseudonym YONIQ , a new version of the popular MMSSTV software is born for communication through slow scan television or SSTV. The idea is to provide the popular software with certain functionalities , to a greater or lesser extent, demanded by many of its users over time . YONIQ maintains the charm and most of the functions of the original software, but also provides you with other functions that manage to place it within the segment of utilities intended for radio amateurs of the 21st century . A necessary and powerful update since the release of version 1.13 10 years ago. This has been created from the implementation of new code and the modification of part of the source code provided through GITHUB under the GNU license, as indicated at http://mm-open.org/ . YONIQ is not a new program , but a continuation and update of the wonderful work done by JE3HHT which he called MMSSTV. So it is simply  a version of the original software , sharing its GNU license as its rightful creator Makoto Mori wishes.
