Abstract
A magnetic video reproducing apparatus employs a rotating two-head system, a helical scanning system and an azimuth system, and is capable of reproducing a video signal recorded in a recording medium at a high speed faster than the recording speed. The output side of a reproducing circuit (24) is connected with a delay circuit (31) for delaying a reproduced composite video signal for the period of about one field. The output directly generated from the reproducing circuit (24) and the output delayed by the delay circuit (31) for the period of about one field are switched by a changeover switch (32) at predetermined timing. Since, in fast reproducing operation, noises appear in the signal for predetermined periods within one field, the changeover switch (32) is so switched as to output the signal delayed for the period of one field including no noises during the subject periods. Such switching operation is performed by a vertical synchronizing signal separation circuit (33) for separating a vertical synchronizing signal included in the composite video signal, at regular intervals in synchronization with the signal.
