ABSTRACT:
A video signal converting device is capable of converting an analog composite signal into a proper digital signal with a small delay even if the analog composite signal contains much jitter. The video signal converting device has a sampling clock output unit for outputting a sampling clock signal having a frequency which is 4n times the frequency of a burst signal contained in the analog composite signal (n represents a positive integer of 2 or greater), and an analog-to-digital converting unit for converting the analog composite signal into a digital signal based on the sampling clock signal output from the sampling clock output unit.
