Abstract: 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.

Abstract: A gateway apparatus is capable of distributing audio, video, and/or data signals in a household and/or business dwelling using the existing coaxial cable infrastructure.

Abstract: A server apparatus is capable of distributing audio, video, and/or data signals in a household and/or business dwelling using the existing coaxial cable infrastructure. According to an exemplary embodiment, the server apparatus includes a receiving element operative to receive signals from a broadcast source. First processing elements generate first analog signals responsive to the received signals. Second processing elements generate second analog signals responsive to the received signals. The first analog signals are provided to a first dent device via a coaxial cable connecting the server apparatus and the first client device. The second analog signals are provided to a second client device via the coaxial cable connecting the server apparatus and the second client device.

Abstract: 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.

Abstract: A power supply for a satellite receiver system includes a dual input supply voltage arrangement. When a higher output voltage is selected, a source of a lower supply input voltage is coupled to an input main current conducting terminal of a series pass transistor. On the other hand, when a lower output voltage is selected, a source of a lower supply input voltage is coupled to the input main current conducting terminal of the series pass transistor. A comparator senses a magnitude of an output voltage produced by the series pass transistor. When, as a result of an over current condition, the output voltage is lower than a reference threshold level, any selection of the higher output voltage is automatically overridden and the source of the lower supply input voltage, instead, is coupled to the input main current conducting terminal of the series pass transistor.
