VIDEO FRAME SYNCHRONIZATION SYSTEM, VIDEO PROCESSING DEVICE AND VIDEO FRAME SYNCHRONIZATION METHOD
Document Type and Number:
WIPO Patent Application WO/2020/061785
Kind Code:
A1
Abstract:
Disclosed is a video frame synchronization system, comprising: a synchronization signal detection comparator, comprising a reference field synchronization signal input end, a feedback field synchronization signal input end and a detection comparison result output end; a controller connected to the detection comparison result output end of the synchronization signal detection comparator; a programmable clock generator connected to the controller; a video timing generator comprising a video timing configuration parameter input end, a pixel clock signal input end and a video timing signal output end, wherein the video timing configuration parameter input end is connected to the controller, the pixel clock signal input end is connected to the programmable clock generator, and the video timing signal output end is connected to the feedback field synchronization signal input end of the synchronization signal detection comparator; and a video encoder connected to the video timing signal output end of the video timing generator. Further disclosed are a video processing device and a video frame synchronization method.
