Timebase axis error compensation apparatus in an information recording/reproduction apparatus

The timebase error compensation apparatus in a video tape recorder (VTR) for compensation for a timebase error included in a reproduced video signal, said apparatus comprising:

• delay means for outputting a first delay signal and a second delay signal, wherein said first delay signal is generated by delaying said reproduced video signal for one horizontal scan period, and wherein said second delay signal is generated by delaying said reproduced video signal for two horizontal scan periods;
• signal generation means responsive to a drum pulse generated in said VTR for generating a control signal which represents one line of a horizontal scan of said reproduced video signal corresponding to a first horizontal sync signal;
• calculation means for performing an arithmetic operation on said reproduced video signal and said second delay signal to generate an output signal;
• changeover means responsive to said control signal for selecting for output either the output signal of said calculation means or said first delay signal;
• and
• compensation means for compensating for the timebase error included in an output signal of said changeover means.
