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.

Claims

1. A server apparatus, comprising:

receiving means for receiving broadcast signals;

first processing means for generating first analog signals responsive to said received signals;

second processing means for generating second analog signals responsive to said received signal, wherein the first analog signals have a different encoding than the second analog signals, and said first analog signals are provided to a first client device via a transmission medium connecting said server apparatus and said first client device in response to a first request signal requesting a first desired processed analog signal by identifying a first program and further wherein said second analog signals are provided to a second client device via said transmission medium connecting said server apparatus and said second client device in response to a second request signal requesting a second desired processed analog signal by identifying a second program; and

control means for detecting available frequency bands on said transmission medium, wherein said available frequency bands are used to provide said first analog signals to said first client device and to provide said second analog signals to said second client device (60), thereby causing said transmission medium to be shared between said processed analog signals and cable broadcast signals distributed over said transmission medium.

2. The server apparatus of claim 1, wherein said transmission medium includes RG-59 cable.

3. The server apparatus of claim 1, wherein said broadcast source includes a satellite source.
