Apparatus for transmitting image signals

摘要

An apparatus for transmitting images over optical cables including a red image signal, a green image signal, and a blue image signal output from a personal computer, a clock signal indicative of the starting points of data frames of the image signals, an enable signal indicative of scan and blank periods of the image signals, a vertical synchronization signal and a horizontal synchronization signal. A reference signal generator (2) generates a reference signal (SR) having predetermined data when the blank period starts in accordance with an enable signal (EN). The reference signal is transmitted during the blank period between scan periods containing the red, green and blue image signals and can be used to resynchronise the phase of each image signal to correct for phase errors occurring during transmission.
