Drop-out compensation circuit of still video reproducer

Abstract

Abstract PURPOSE:To carry out compensation having excellent vertical correlation by taking out electrical signals delayed by 0.5hr from the nonreproducing side and by compensating drop-out of a head at the reproducing side. CONSTITUTION:The titled device is provided with preamplifiers 1 and 2 to amplify reproducing signals of heads 3 and 4, respectively, and double switches 5 to switch a reproducing head at every field. Through this switch 5 the 1st circuit 6 for reproduction and the 2nd circuit for compensating drop-out are exclusively and alternatively connected to either heads 3 or 4, and electrical signals from either heads 3 or 4 are led to an adder 8 through the circuit 3 or 4. Then the electrical signal is outputted from the adder 8 to a monitor 9 as a reproducer and display device.
