Abstract
A magnetic tape recorder/reproducer for digital video signals has an error recognition circuit unit as well as circuit units for correction and/or concealment of recognized errors in the video signal. During a tracking adjustment procedure a manual control added to the tracking adjuster reduces the capability of error correction and/or concealment by black-marking erroneous words recognized in the luminance portion of the digital video signal.
