SaTCR-1Satellite channel router
Rev. 1
DESCRIPTIONRelaying satellite signals from the rooftop dish to
multiple receivers around the home, Digital Video
Recorders (DVR) or throughout an apartment
block is an expensive proposition for system
installers. The SaTCR-1 satellite channel router
addresses this problem by combining up to eight
input signals onto a single cable. These signals
are then decoded by a corresponding number of
tuners, potentially distributed across many set-top
boxes.
The SaTCR-1 device is intended for use in LNBs
or switchers in satellite receivers. The device shifts
the frequency of any input signal to a fixed
intermediate frequency. The output signal is band-
pass filtered generating a narrow band output.
By combining several SaTCR-1 devices, a
corresponding number of sub-bands may be
generated and multiplexed together.
This composite band can be made of different
independent channels issued from different LNB
