Abstract
In a video signal transmission system and method, a video signal and a pre-defined synchronization signal, generated according to the logic status of first control signals, are converted into first DC-balanced data and second DC-balanced data, respectively. The first data and second data are converted into a first serial data stream and a second serial data stream, respectively, and the data streams are transmitted over a first channel. Third data and fourth data are detected by correcting skew of the first serial data stream and the second serial data stream received through the first channel. The first data is encoded and transmitted so that the second data and the third data are not the same. The first serial data stream is transmitted over the first channel in response to an activated second control signal, while the second serial data stream is transmitted over the first channel in response to a deactivated second control signal.
