Conversion from CVBS to SDI based On FPGA

Serial Digital Interface (SDI) has become a standard video interface gradually. The former methods to implement the SDI cause much costs and low agility. Aiming at the situation that analogue and digital coexist, this paper uses a FPGA-based way to design the SDI, it mainly expounds the scheme of the SD SDI design, and analyses its structures and function of each module, which is implemented by Hardware Description Language.
