Satellite receiver with a controllable head end

摘要

The satellite reception system has a controlled head station with a converter (16) employing a number of converter modules (17,18), receiving satellite transmission programmes within a respective reception plane. The outputs of the converter modules are fed to a number of subscribers (45) via an output collector field (41) and signal distribution lines (43). A microcontroller control device (33) controls the local oscillators (21,23) within the converter modules, with the individual subscribers incorporating a control facility for the corresponding reception converter using a random distribution method.
