Error encoding method and apparatus for satellite and cable signals

摘要

A signal distribution system and method distributes an error-encoded satellite communication signal over a cable network to a number of receiver units within a multiple dwelling unit. The system and method receives and decodes the satellite communication signal to produce a data signal and an error indication that indicates whether an uncorrected transmission error is present in the data signal. The error indication is then combined with the data signal and an information signal to produce a combined signal which is then error encoded and transmitted over the cable network to the receiver units. The receiver units decode the combined signal to produce the data signal, the information signal, the error indication and a further error indication that indicates whether the data signals have experienced an uncorrected error during communication over the cable network. The receiver units use both the error indication and the further error indication to determine if the received data signal has one or more errors therein.
