HIGH-SPEED REPRODUCING CIRCUIT FOR VIDEO TAPE RECORDER

PROBLEM TO BE SOLVED: To reduce out-of-synchronism and to prevent an image from hardly being viewed by deviating skew distortion appearing on a screen to the left side. SOLUTION: When the five-times speed reproducing speed of an LP mode is set in a high-speed reproducing circuit 11, for example, vid...

Summary:PROBLEM TO BE SOLVED: To reduce out-of-synchronism and to prevent an image from hardly being viewed by deviating skew distortion appearing on a screen to the left side. SOLUTION: When the five-times speed reproducing speed of an LP mode is set in a high-speed reproducing circuit 11, for example, video signals in a first field are read out by 1st LP head 14a and a 2nd SP head 16b. The respective reproduced video signals are inputted to a 1st reproduced video signal output circuit 18a and reproduced video signals at high signal level are outputted. Similarly, video signals in a second field are read out by a 2nd LP head 14b and a 1st SP head 16a and selectively outputted by a 2nd reproduced video signal output circuit 18b. The reproduced video signals from the 1st and 2nd reproduced video signal output circuit 18a and 18b are switched for each field by a head switching circuit 20.
