Document Type and Number:
Japanese Patent JP2797436
Kind Code:
B2
Abstract:
An apparatus for controlling the time base of a first video signal, for example, from a character signal generator, to be superimposed on a second video signal reproduced from a record medium, as by a VTR, and having a time base which is fluctuating, includes a detector for detecting time base fluctuations of the second video signal and producing an output signal representing the time base fluctuations, and a time base control circuit for controlling the time base of the first video signal on the basis of the output signal from the detector, such that the time base of the first video signal is correlated to the time base fluctuations of the second video signal.
