Satellite signal frequency translation and stacking
An outdoor satellite receiving unit (ODU) receives several independent satellite signals, selects two signals with a switch matrix, downconverts the two signals to a bandstacked signal with a high and a low band signal, and outputs the bandstacked signal on the same cable to receiver units. Several satellite signals can be selected in groups of two or more and output to independent receiver units. Signal selecting is performed at the received radio frequency (RF) and bandstacking is performed with a single downconversion step to an intermediate frequency (IF). Channel stacking on the same cable of more than two channels from several satellites can be achieved by using frequency agile downconverters and bandpass filters prior to combining at the IF output. A slow transitioning switch minimizes signal disturbances when switching and maintains input impedance at a constant value.

Video Alternate Network Access Points and Receivers
Concepts and technologies for video alternate network access points and receivers that enable wireless delivery of video content to multiple customer premises over a service area are provided herein. In an embodiment, a system includes a satellite dish receiver that is configured to receive a satellite video feed, and a video alternate network access point that is communicatively coupled to the satellite dish receiver. The video alternate network access point can perform operations that ingest the satellite video feed directly from the satellite dish receiver. The operations can activate a microcell transceiver embedded within the video alternate network access point, and identify a multicast-broadcast single-frequency network channel. The operations can then transmit, to a video alternate network receiver device from the microcell transceiver, the satellite video feed over at least the multicast-broadcast single-frequency network channel.
Satellite Dish LNB, Satellite Broadcast Signal Receiver and Methods of Operation
Low-noise block downconverter (LNB) of a satellite dish receives a request from a satellite broadcast signal receiver to transmit a signal for a channel to the receiver. If the channel requested by the receiver is different from a channel requested by another satellite broadcast signal receiver, the LNB in response provides a signal for the channel requested by the receiver at a frequency that is allocated to the receiver. If the channel requested by the receiver is the same as a channel requested by another satellite broadcast signal receiver, the LNB provides an instruction to the requesting receiver for the receiver to retune to the frequency used for the other satellite broadcast signal receiver. The requesting receiver can then receive the signal for said channel which is being provided by the LNB at the frequency used for the other satellite broadcast signal receiver.
