ABSTRACT:
A display synchronization signal generator capable of displaying a stable image regardless of changes in a transmission speed of a received digital broadcast signal in a digital broadcast receiver. The display synchronization signal generator includes a speed difference detector, a vertical period change amount detector, a vertical synchronization signal generator, a pixel clock signal generator, and a horizontal synchronization signal generator. The vertical period change amount detector detects a change amount in a vertical period of an image to be displayed, based on a detected speed difference. The vertical synchronization signal generation unit generates a vertical synchronization signal with a period that is changed based on the change amount detected by the vertical period change amount detector. The pixel clock signal generator generates a pixel clock signal based on a basic clock signal. The horizontal synchronization signal generator generates a horizontal synchronization signal in response to the pixel clock signal.
