Abstract
A satellite reception assembly may include a housing configured to support receipt and handling of a plurality of satellite signals. The housing may include circuitry incorporating integrated stacking architecture for supporting and/or providing channel and/or band stacking whereby particular channels or bands, from multiple satellite signals that are received via the satellite reception assembly, may be combined onto a single output signal that may be communicated from the satellite reception assembly to a gateway device for concurrent distribution thereby to a plurality of client devices serviced by the gateway device.
Claims22
A system, comprising:
- a gateway, and
- a satellite reception assembly configured to communicate with the gateway via a single link which forms existing connectivity between the satellite reception assembly and the gateway;
- wherein the gateway is configured to deliver requested content to a client device of a plurality of client devices via a network and generate an output signal according to the requested content for the client device,
- wherein the satellite reception assembly is configured to frequency stack a plurality of satellite signals to obtain stacked content through channel stacking or band stacking and equalize the stacked content;
- and
- wherein the satellite reception assembly comprises:
- a plurality of input mixers, each of the plurality of input mixers being configured to process a component of a satellite signal;
- a plurality of first filters configured to respectively process a plurality of first mixer output signals of the plurality of input mixers;
- a plurality of analog-to-digital convertors (ADCs) configured to respectively process a plurality of first filter output signals of the plurality of first filters;
- a digital front end (DFE) providing crossbar combining/switching configured to map a plurality of ADC output signals of the plurality ADCs to a plurality of DFE output signals, a number of the plurality of DFE output signals being less than a number of the plurality of ADC output signals;
- a plurality of digital-to-analog convertors (DACs) configured to respectively process the plurality of DFE output signals;
- a plurality of second filters configured to respectively process a plurality of DAC output signals of the plurality of DACs;
- a plurality of output mixers configured to process a plurality of second filter output signals of the plurality of second filters;
- and
- a plurality of adders configured to process a plurality of second mixer output signals of the plurality of output mixers to output a number of adder output signals, a number of the adder output signals being less than a number of the plurality of second mixer output signals.

A method, comprising:
- receiving, by a gateway from a client device of a plurality of client devices, a request for content selected from a plurality of television (TV) channels;
- receiving, by the gateway from a satellite reception assembly, a single wire input signal comprising the plurality of TV channels via a single link;
- and
- delivering, by the gateway to the client device, the content requested over a network;
- wherein the single wire input signal is generated by the satellite reception assembly by stacking one or more portions from the content requested and at least one other signal to generate a stacked signal on the single link through channel stacking or band stacking, and applying power equalization to the stacked signal to prevent leakage of power from at least one frequency into adjacent frequencies across an entire frequency band corresponding to the one or more portions from the content requested and the at least one other signal,
- wherein the satellite reception assembly comprises:
- a plurality of input mixers, each of the plurality of input mixers being configured to process a component of a satellite signal;
- a plurality of first filters configured to respectively process a plurality of first mixer output signals of the plurality of input mixers;
- a plurality of analog-to-digital convertors (ADCs) configured to respectively process a plurality of first filter output signals of the plurality of first filters;
- a digital front end (DFE) providing crossbar combining/switching configured to map a plurality of ADC output signals of the plurality ADCs to a plurality of DFE output signals, a number of the plurality of DFE output signals being less than a number of the plurality of ADC output signals;
- a plurality of digital-to-analog convertors (DACs) configured to respectively process the plurality of DFE output signals;
- a plurality of second filters configured to respectively process a plurality of DAC output signals of the plurality of DACs;
- a plurality of output mixers configured to process a plurality of second filter output signals of the plurality of second filters;
- and
- a plurality of adders configured to process a plurality of second mixer output signals of the plurality of output mixers to output a number of adder output signals, a number of the adder output signals being less than a number of the plurality of second mixer output signals.
