    摘要： 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.

    摘要： In a synchronous processing circuit in the figure, an LPF (1) separates a vertical synchronizing separation signal (6) from a composite signal (5) from the outside, a 1/2 frequency division circuit (4) outputs a vertical phase detection signal (9) obtained by dividing the vertical synchronizing separation signal (6) into 1/2, a phase delay unit (2) to which the composite signal (5) is input outputs a plurality of different phase-delayed horizontal synchronizing signals (19 to 24), and a vertical synchronizing signal reproducing circuit (3) uses the vertical synchronizing separation signal (6) and the plurality of phase-delayed horizontal synchronizing signals (19 to 24) to output a vertical synchronizing signal (8) for which a phase relation with a horizontal synchronizing signal is determined.
