ABSTRACT:
A television transmission system includes a transmitter that transmits a digital video signal, including an error code, that is dispersed in one sense and a receiver having a selectively reversible complementary dispersal filter and an error detection circuit for recovering the transmitted signal. The error rate of the received signal is used to automatically select the correct sense of the receiver dispersal filter.
