Abstract

The invention discloses a solving method for multi-picture division cracked screen display of a high-definition video. The solving method adopts an SDI interface circuit, an HDMI interface circuit, a matrix chip, an SDI signal decoding circuit, an HDMI signal decoding circuit, an FPGA and a configuration circuit thereof, a DDR2 SDRAM data storage circuit and an HDMI signal coding circuit, wherein after the matrix chip receives SDI/HDMI signals from the SDI interface circuit and the HDMI interface circuit, the SDI signal decoding circuit and the HDMI signal decoding circuit decode the signals and convert into parallel digital signals; and then the parallel digital signals enter the FPGA and the configuration circuit thereof to extract, store and compound nine-channel video signals, and the processed data is converted into HDMI video signals by the HDMI signal coding circuit. The solving method provided by the invention can effectively solve the problem about multi-picture division cracked screen display of the high-definition video, and delay during display can be controlled within a frame by using the method.

Description

technical field [0001] The present invention relates to the field of video processing, in particular to a solution to high-definition video multi-picture split screen display. Background technique [0002] With the development of technologies such as computers, DSP, and ultra-large-scale integrated circuits, screen splitters have begun to adopt hardware design. First, convert each video signal into a digital video signal; then, process each video signal in the digital field. The design and debugging of the circuit have been greatly improved. However, there are many independent logic circuits used in the design, and some even use dedicated DSP chips to process the segmentation of video images. Although it can meet the requirements for video image data processing speed, it still needs an additional CPU to coordinate the work of the system, so that the whole system still appears to be bulky and the system cost is relatively high. With the continuous development of semiconduc...
