Abstract
A video information reproduction system includes first and second video information reproduction devices. A first synchronization signal processor of the video information reproduction device as a master device generates a phase synchronization signal including a first vertical synchronization signal and a first counter value and sends it to the second video information reproduction device. A second synchronization signal processor of the second video information reproduction device as a slave device compares the phase synchronization signal with a second vertical synchronization signal on the basis of a second video clock signal, and a second clock generator changes the frequency of a second decode reference clock signal on the basis of a result of the comparison.
