ABSTRACT:
A portable video recorder transduces video signals onto an elongated medium. The transducer-to-medium velocity is controlled by a rotary member such as a capstan, turntable or headwheel. In portable applications, motion of the recorder causes accelerations or variations in velocity of the rotary member which affects the regular spacing on the medium of sync or timing signals transduced thereto. Regular spacing of sync signals is desirable for good reproduction on playback. Timing or sync signals generated by the rotary members are used to control the rate of the timing signals of the video to be recorded as they are applied to the transducer, thereby making the spacing regular.
