ABSTRACT:
Video reproduction apparatus records a field of a high resolution time-division-multiplex (TDM) video signal on first and second adjacent tracks on a magnetic tape. A head switch signal is included within the TDM video signal recorded on the tape in order to minimize skew errors which may occur in mid-field when switching between videosignals sequentially played back from the first and second tracks. Each track has recorded thereon a plurality of horizontal lines of color video signals in a time-divisional-multiplex format including a compressed horizontal sync service signal and compressed video component signals arranged in time sequential order. A head switch signal is inserted in the compressed horizontal sync service signal of a designated horizontal line signal at the end of the upper half of the field recorded on the first track. During playback, a head switch detecting circuit detects the head switch signal in the designated line of the upper half field signal to effect a switch during the horizontal sync service interval between the signals played back from the first and second tracks.
