Abstract: The invention relates to the video signal processing field, more particularly to a digital video data double transfer method. The method performs decoding, sampling and synthesis for input ITU-656 digital video signals with multipath resolution factor of D1 or 4CIF, wherein, each four lines of video signals are synthesized to one line of ITU-656 digital video signal with resolution factor of D1 or 4CIF; redefines the information format of the video signal input/output interface as ITU-656 taxonomy and then input the synthesized two lines or multiple lines of digital video signals with resolution of D1 or 4CIF to a digital video signal processing unit by the digital video interface. The invention solves the problem of digital video signal processing chip high efficiency application, and improves the video signal transfer efficiency greatly, with wide application prospects.
