A system for increasing the capacity of distribution networks intermediate frequency signals of satellite.

摘要

System to increase the capacity of distribution networks intermediate frequency signals satellite, which consist of a header receiving channels (CH) with the original signals in QPSK format, processes them and sends them to a converter that sends their output signals to the user receiver, wherein the header is processed at least some of the channels (CHP) to QAM format and because the converter converts the format QAM modulation in QPSK modulation format. Application in digital television.
