Abstract (en)
[origin: EP0405004A2] In satellite receiving systems for receiving communication satellites or communication satellites and DBS satellites in the standardised first satellite intermediate frequency band, the DBS channel pattern cannot be filled with the 40 channels provided for it due to the greater bandwidth in the communication satellite signals. To create optimum utilisation of this intermediate-frequency band, the invention provides for each transmission channel a converter unit (UE1 to UE5), which in each case consists of a frequency divider (FT) by means of which the channel bandwidth of the communication satellite signals is halved, and an up-converter (U2) converting the respective transmission channel from the lower frequency position in a free channel in the DBS channel pattern of the first satellite intermediate-frequency band, following each frequency divider (FT). <IMAGE>
