Abstract
Apparatus is provided for use in a digital video signal playback device of the type having a record medium in which plural channels of digital video signals are recorded in a like plurality of tracks. Plural transducers, such as playback heads, are associated with respective ones of the channels and reproduce the digital video signals from the plural tracks, each transducer normally reproducing a respective, predetermined channel of the digital video signals. A detector detects the particular channel with which the digital video signal reproduced by each transducer is associated. A signal interchanger is provided with plural channel outputs and is responsive to the detector for directing digital video signals which have been reproduced by transducers associated with channels which differ from the channels of the reproduced digital video signals to the proper channel outputs as determined by the detector. Thus, regardless of the particular transducer which reproduces the digital video signals from a track, that digital video signal nevertheless is supplied to its proper channel output.
