Abstract

PURPOSE: To attain color TV transmission of high quality by introducing the light- wavelength-division multiplication technique employing optical fiber.
CONSTITUTION: Through photoelectric conversion operations 201 to 203, wavelengths (λ1) to (λ3) are obtained from RGB signal of pickup tube 19. By multiplying 21 those light wavelengths, signals are focused and inputted to optical fiber 24. The pickup tube and photoelectric converters are supplied with synchronizing signal 23. After being separated 25 into respective wavelengths, (λ1) to (λ3) are photoelectrically converted 261 to 263, thereby regenerating three primary color signals. Each signal is applied to each grid of picture tube 31 to regenerate a picture. As for the synchronizing-deflecting signal at the reception side, some of the output of amplifier 283 for regenerative B signals is distrbuted to synchronizing-signal regenerating-deflecting circuit 29, where a prescribed signal is generated and applied to picture tube 31. convergence circuit 30 operates in the same way as a NTSC system. This method simplifies the circuit constitution and enables the signal transmittion of high quality.
