Until 2005, we used various computers to store our data and to make our experiments. In 2005, we began some work to specify and set-up dedicated equipment to the experiments on very large collections of data. During 2006, we specified our first complete platform, which is organized around a very large storage capacity (between 64 and 100Tb), and containing acquisition devices (for Digital Terrestrial TV), computing servers and data servers. Two softwares were developed: one to manage the acquisition process and all the data already stored, the second one to allow an easy access to the data from processing programs (tmx-DIVA-solution). The platform will be completed with dedicated software to manage large collections of still images and all the metadata associated with the data. This platform is paid by a joint effort of INRIA, INSA Rennes and University of Rennes 1.
