Abstract
A direct television broadcasting satellite facility (S1, S2, S3) having at least two coverage areas (T1, T2). At the beginning of the life of the facility, with present Standards, only two satellites (S1, S2) each having two beams (F1 & F2 and F'1 & F'2) are used, each satellite having 12 channel and redundancy amplifiers for five channels. When high-definition television is subsequently introduced progressively, the amplifiers will be coupled together in parallel and in pairs, and at least one additional satellite (S3), identical to the two initial satellites, will be launched when required.
