Abstract
A video processing device includes: a deserializer that both converts a serial digital interface signal received as input to parallel data and extracts a clock; format detection means that both detects a video data format that is included in the parallel data that were converted by the deserializer and supplies clock ratio information that indicates the ratio of the clock frequency and the pixel clock frequency stipulated by the format; pixel clock generation means that generates a pixel clock based on the clock that was extracted by the deserializer; saving means that saves video data and supplies the saved video data in synchronization with the pixel clock; write control means that, based on the clock ratio information, divides the video data that are contained in the parallel data that were converted by the deserializer into two or four portions and saves the divided data in the saving means; and an unpack processor that, synchronized with the pixel clock, subjects the data that are supplied from the saving means to processing that accords with the video format.
