Abstract
A video signal with superimpose character data reproducing apparatus reproduces MPEG compressed video signal from a CD-ROM. The compressed video signal read from the disc includes a plurality of blocks each having a header with a character data. The compressed video signal is expanded by an expander to a plurality of component signals, which are then modulated in modulator to a composite video signal. An extractor extracts the character data and temporarily stores it in flop-flops. The extracted character data is serially inserted in the composite video signal by synthesizer in a predetermined timing.
