Signal transmitting device, transmitter and receiver

A signal transmitting device comprising:

• a transmitter that includes:
• a first electro-optical converter electro-optically converting original electrical red video signal in original video signal according to DVI standard into optical red video signal;
• a second electro-optical converter electro-optically converting original electrical green video signal in the original video signal into optical green video signal;
• a third electro-optical converter electro-optically converting original electrical blue video signal in the original video signal into optical blue video signal;
• a parallel/serial converter converting original electrical parallel signal having a lower transfer rate than a transfer rate of the original video signal into original electrical serial signal based on an original clock signal of the original video signal;
• and
• a fourth electro-optical converter electro-optically converting the original electrical serial signal transmitted from the parallel/serial converter into optical serial signal;
• a receiver that includes:
• a first optical-electro converter optical-electro converting the optical red video signal into electrical red video signal;
• a second optical-electro converter optical-electro converting the optical green video signal into electrical green video signal;
• a third optical-electro converter optical-electro converting the optical blue video signal into electrical blue video signal;
• a fourth optical-electro converter optical-electro converting the optical serial signal into electrical serial signal;
• a clock signal generator generating clock signal from the electrical serial signal;
• and
• a serial/parallel converter converting the electrical serial signal into electrical parallel signal based on the clock signal,
• four optical fibers that optically connect the first to fourth electro-optical converters to the first to fourth optical-electro converters respectively.
