Abstract
A DD converter circuit for interpolating a digital video signal which is locked to a 14.3-MHz burst clock to convert the sampling data so as to be locked to a 13.5-NHz free-run clock, and a frame memory circuit for writing a digital video signal which is output by the DD converter circuit on the 14.3-MHz burst clock as well as reading the written digital video signal on a 13.5-MHz clock S are included. Therefore, a video signal processor which can realize the rate conversion of the digital video signal without using an analog PLL circuit can be provided.
