ABSTRACT:
A method of reproducing video signals from a magnetic recording medium like a magnetic tape for a VTR to obtain high-quality video pictures even when dropouts occur in the medium, which includes the steps of separating synchronizing information from the video signals reproduced from the magnetic recording medium, detecting a dropout duration from the reproduced video signals, generating complete synchronizing information during a whole period of writing the signals in image information memories by compensating lost synchronizing information during the dropout, generating write address signals on the basis of the generated synchronizing information, writing reproduced video signals the memories on the basis of the generated write address signals while no dropout occurs, and leaving unchanged previously written video signals while a dropout occurs. According to an apparatus implementing the above method, reproduced pictures of high quality are obtained without jitters and skews due to dropouts.
