摘要： A gateway apparatus is capable of distributing signals such as audio, video, and/or data signals in a household and/or business dwelling using the existing coaxial cable infrastructure, and the signal distribution is controlled using the coaxial cable infrastructure as a back channel. According to an exemplary embodiment, the gateway apparatus includes signal processing elements for receiving signals from a broadcast source and processing the received signals to generate processed analog signals. A back channel demodulator receives a request signal from a client device via a coaxial cable connecting the gateway apparatus and the client device. The processed analog signals are provided to the client device via the coaxial cable responsive to the request signal.

摘要： A server apparatus is capable of distributing recorded content in a household and/or business dwelling using the existing coaxial cable infrastructure. According to an exemplary embodiment, the server apparatus includes a front-end processor operative to receive signals from a broadcast source and process the received signals to generate digital data. A memory is operative to record the digital data. A controller is operative to enable retrieval of the digital data from the memory. An encoder is operative to encode the retrieved digital data with error correction data to generate encoded digital signals. A digital-to-analog converter is operative to convert the encoded digital signals to analog signals. A modulator is operative to modulate the analog signals to generate processed analog signals, which are provided to a client device via a coaxial cable connecting the server apparatus and the client device.

摘要： An RF multiple switching apparatus, such as one included in or coupled to a broadcast satellite signal receiver, having a plurality of multiple RF signal input ports for receiving respective ones of a plurality of RF signals, such as broadcast satellite television signals, utilizes a relative signal strength indicator, such as an automatic gain control signal, to determine the difference between the actual input signal that is present at one of the plurality of signal input ports and a false signal that appears to be present at another signal input port of the plurality of signal input ports due to the RF signal bleeding between the multiple signal input ports. During a setup configuration determination or routine, the switching apparatus steps through each RF signal input, extracts pertinent transmission network (such as a satellite transmission network) information, determines a relative signal strength indicator for the RF signal, and compares the obtained information. Setup data for each RF signal input is stored according to the comparison.
