Patent ID: 7102629

Claim:
A video signal transmission method comprising: encoding a binary video signal and a pre-defined binary synchronization signal, generated according to the logic status of first control signals, into first DC-balanced binary data and second DC-balanced binary data, respectively; converting the first DC-balanced binary data and second DC-balanced binary data into a first serial binary data stream and a second serial binary data stream, respectively, and transmitting the first and second serial binary data streams over a first optical channel of an optical transmission system; detecting third binary data and fourth binary data by correcting skew of the first serial binary data stream and the second serial binary data stream received through the first optical channel; and encoding and transmitting the first binary data so that the second binary data and the third binary data are different; wherein the binary video signal and the pre-defined binary synchronization signal include N bits, where N is a natural number, and the first binary data through the fourth binary data each include (N+M) bits, where M is a natural number.
