The distribution for satellite of the current platform of terrestrial digital television (TDT), with more than 20 channels, is on the table of the broadcasters and implied entities. RTVE is valuing this solution together with Hispasat, the same exposition that is already in march in other countries like the United Kingdom and France.

The Hispasat satellites, thanks to his powerful coverage, are the support of the network of transport of the múltiplex of TDT on which there feed the re-issuers and “gap - filler“ of the network of earthly diffusion TDT, by means of linkage of very high quality and on an availability superior to 99,99 %.

The target is to use this sign of satellite to reach 100 % of the Spanish population, without incurring excessive costs. The use of terrestrial networks to come to the last one 15 % is very expensive, therefore the best option is to resort to the satellite to achieve an effective coverage. Nevertheless, since the coverage of the satellite does not limit itself to a certain country, there can be problems, due to the contents emission beyond the geographical limitation of the rights, which have to be solved by means of some protection system. For such an end, the technological Spaniard SIDSA is commercializing KeyFly CDN, a system that is designed to protect the signs of the terrestrial digital television that are distributed across satellite.

KeyFly CDN allows so much emission openly as of payment. As desencriptación support one can use a module of conditional access that can insert both in professional decoders and of consumption for descodificar the sign, guaranteeing the investments already realized in the teams or reception points.

KeyFly CDN is part of the products for protection of contents of the family KeyFly of SIDSA, a safety system for every environment with KeyFly CDN and KeyFly Broadcasting like his principal banners. KeyFly Broadcasting is a System of Conditional Access that offers solutions on the subject of safety known till now on the market of the protection systems of contents for diffusion and that all kinds of business models supports.
