Abstract
A data reproduction apparatus for character multiplexing video signal includes an A/D converter circuit for converting a character multiplexing video signal into a digital video signal, an FC detecting/clock generating circuit for detecting an FC signal contained in the digital video signal to generate a clock signal for character data reproduction, a delay circuit for delaying the digital video signal by a period of time corresponding to time required for the FC detecting/clock generating circuit to generate the clock signal, and a data reproducing circuit for reproducing character data by sampling the digital video signal which is time-adjusted by the delay circuit by use of the clock signal.
