PROBLEM TO BE SOLVED: To provide a nonlinear edit system that can efficiently transfer a list of various parameters for real time processing of an video edit. SOLUTION: A parameter list is transferred between a PC unit and a video processing unit VPU through a dual port DP RAM. A packet for data transfer includes a packet size 50, a list number 51, a list size 52, a list ID 53, a layer number 54, a layer size 55, a layer ID 56, a base address 57, an offside address 58, a data size 59, a data number 60, data 61A, 61B, 61C or the like. Each of the data 61A, 61B, 61C respectively corresponds to a 24-byte transfer structure. Then a data rewrite position with respect to the transfer structure is designated by using the base address 57 or the like to transfer only required data.
