This paper introduces an implementation method of audio and video fusion equipment based on VPX architecture.The equipment adopts the form of "integrated framework + functional module", and the whole machine design conforms to vita65 specification. The equipment receives audio and video signals transmitted by SDI and IP, and uses Hisilicon series chips and FPGA chips to realize H.264 codec compression, image scaling, splicing, preview, storage and other functions. The equipment adopts configuration management software, which can create, edit and save a variety of configuration schemes. Through physical verification, the equipment has the advantages of high system integration, stable and reliable operation.
