Research On High Definition Video And Image Transmission System Based On Gigabit Network

Gigabit Ethernet technology has the characteristics of high real-time,fast transmi ssion and good portability,we study the solutions of the current high-definition vide o transmission system,By contrast,in view of the deficiencies and shortcomings of ex isting programs,present a high definition video transmission scheme based on Gigabi t network is proposed,accomplish the digital transmission of uncompressed HD video.FPGA collects the DVI video data by digital camera or interface chip,Cache processing by SDRAM/FIFO,FPGA group data processing of the data to be transmitted to the h ost computer to decode and display the data.Through the simulation,assembly,debu gging and verification of the system,the system can transmit high-definition video,ba sically completed the relevant design requirements,has a certain practical value.This scheme abandons the 100m network video transmission problem resolution is not enough,method for implementing point to point video data transmission using pre set MAC address,increased bandwidth usage,improve the video transmission speed,Com pared with the traditional FPGA system,the paper uses the kernel to realize gigabit n etwork video transmission,Greatly reduce the utilization of system resources.Reduce the cost of gigabit network video transmission,At the same time,it is easier to configure the system,Popularization and application of high definition video transmission.This paper introduces the main work of the subject,mainly doing the following a spects of work:1.The simulation and test of UDP transmission protocol have bee:n completed2.Completed Gigabit Network preset MAC address writing3.Completed data communication between Gigabit Network FPGA and PC4.Data communication between two boards is completed5.Completed single board data image transmission6.Double board image data transmission is completedThis paper introduces the working principle of gigabit network video transmission system,The overall design scheme of the system is described,The development platform of the system,hardware design and software design are introduced in detail,Finally,the whole system is simulated and debugged,The feasibility of the scheme is analyzed and verified.Finally,through testing,the fastest transmission speed can reach 938MBps,and the speed can be stably transmitted over 800MBps.
