An image display apparatus which employs a cathode ray tube displays, when an image displayed on a screen of the cathode ray tube is to be corrected against an inclination caused by the terrestrial magnetism, a reference for correction is displayed on the screen of the cathode ray tube so that correction current appropriate for correction of the image against the inclination caused by the terrestrial magnetism can be obtained in a short time.

Image display apparatus and method of correcting image on image display apparatus against inclination by terrestrial magnetism

An optical transmitter converts serial hi-vision digital signals sent from a transmitting side peripheral device over a coaxial cable into serial digital optical signals to transmit the resulting signals over an optical fiber. An optical receiver receives the serial digital optical signals sent from the optical transmitter over the optical fiber to convert the signals into serial hi-vision digital signals to transmit the converted signals over a receiving side coaxial cable to a receiving side peripheral device. This enables transmission of digital signals to the receiving side peripheral device with suppressed signal deterioration without requiring a complex structure.
