Claims

[Scope of utility model registration request]

a first monomulti, which has a metastable period shorter than the horizontal scanning period using a horizontal synchronization signal in a reproduced video signal as a trigger input; and a first monomulti, which has a metastable period longer than the width of the horizontal synchronization signal in synchronization with the first mono multi output. a gate means for controlling passage of a horizontal synchronizing signal at the output of the second mono multi, a third mono multi using the output of the gate means as a trigger input and having a metastable period longer than the horizontal scanning period; A skew detection circuit comprising a flip-flop which uses the third mono multi-output as a set input and inverts at a skew jump position.
