Abstract

The invention discloses a high-definition video seamless matrix based on a FPGA (field programmable gate array). The high-definition video seamless matrix comprises a simulation matrix chip, a high-definition A / D and equilibrium processing chip, an FPGA digital signal seamless switching processing chip and a high-definition D / A and output pre-emphasis processing chip, wherein the high-definition A / D and equilibrium processing chip comprises an SDI interface input decoding chip and a DVI interface input decoding chip, the high-definition D / A and output pre-emphasis processing chip comprises an SDI interface output coding chip and an HDMI interface output coding chip, and the input end of the FPGA digital signal seamless switching processing chip is also connected with a DDR2 memory and an EPCS serial memory. The high-definition video seamless matrix based on the FPGA can support high-definition 1080P and ultrahigh-definition 4K*2K video resolution ratio, can eliminate chattering phenomenon such as instant black screen, blurred screen and the like caused by the switching of different signal video sources, can realize a trick switching effect of seamless pure switching, fade in and fade out and the like by virtue of internal integration under the situation that no other interface product is used and brings about a brand new experience to users.

Description

technical field [0001] The invention relates to a video matrix, in particular to an FPGA-based high-definition video seamless matrix.
