Apparatus for correcting a time base error and for compensating dropouts included in a reproduced video signal

Abstract From the Canadian patent

An apparatus for correcting time base errors and for compensating for dropouts in a reproduced video signal includes a single random access memory for storing digital video data a correct video data producing circuit connected to the memory for producing correct video data from data read out from the memory, a switching circuit controlled by a dropout detecting pulse for supplying either the digital video data or the correct video data to the memory and a control circuit for controlling read and write address operations of the memory. The read and write address operations include the generation of a write address signal indicating a write address at which an output signal of the switching …
