ABSTRACT:
A television distribution system includes a frequency agile satellite transponder down converter operating in the satellite block converted frequency range, typically 950-1450 MHz, along with an IF stage incorporating bandpass filtering and a frquency agile up converter. This arrangement allows a head-end configuration with optimum selection of transponders from one or more satellites and with both vertical and horizontal polarities. The transponders are converted to an available slot allowing twelve slots to accommodate transponders of preference. The block may then be distributed to multiple subscribers in apartment complexes, condominiums and subdivisions.
