发明名称 Video signal reproducing apparatus.
摘要 In a video signal reproducing system which employs therein a head tracking control system in which a reproducing head is moved in the direction substantially perpendicular to its scanning direction usually along each recorded track on a tape to cause a predetermined track skip so as to scan a selected one of the recorded tracks and is provided with a detecting circuit device for detecting the phase of color signal component, for example, the R-Y component of a video signal reproduced from the recorded tracks, an additional circuit (10, 11) is provided for preventing the detection of the phase of color signal component by the detecting circuit device from being in error following a track skip where the number of tracks skipped is such that the phase sequence between successive scanned tracks is incorrect. This is achieved by controlling the detecting circuit device with information about the track skip which is obtained in the head tracking control system.
