Abstract
Generating oscillator signals with which selected signals may be mixed. Such oscillator signals may be generated by dividing a pilot tone, such as a 120 MHz pilot tone found on many cable TV systems. Oscillator signals for demodulating received selected signals may be similarly generated.
Claims6
A method, comprising:
- receiving, at a subscriber premises, selected downstream optical signals out of a plurality of downstream optical signals from an information distribution system, the selected downstream optical signals corresponding to a level of service of a subscriber to the information distribution system;
- converting the selected downstream optical signals to electrical signals;
- transmitting the electrical signals as radio frequency signals to one or more connected devices at the subscriber premises;
- receiving an upstream electrical signal from one of the one or more connected device at the subscriber premises;
- converting the upstream electrical signal into an upstream optical signal;
- transmitting the upstream optical signal to the information distribution system.
