3G-SDI/DVI portable video signal collecting method

Abstract

The invention discloses a 3G-SDI / DVI (3Gbps-Serial Digital Interface / Digital Video Interface) portable video signal collecting method which comprises the following steps of 1) sending location information of a video frame where a parallel video signal and a video stream are located to a caching module, 2) calculating an internal memory address, conducting circulation storing, and sending the parallel video signal to a frame control coding module, 3) coding and outputting the parallel video signal to a DVI coding chip directly, and monitoring each frame of the parallel video signal, 4) sending the parallel video signal in the current internal memory to a processor module with a file system when a specific frame or a problematic frame is monitored, and 5) sending the parallel video signal to a static storing module for storing. The method has the benefits that as an SDI signal is converted to a DVI signal to facilitate analyzing, a video image is analyzed in a static picture by setting slow video playing and a static frame, a specific picture or a video can be stored to the static storing module such as an SD (Secure Digital) card in real time.

Description

technical field [0001] The present invention relates to the field of video acquisition and analysis, and more specifically, relates to a method for acquiring portable high-definition digital video signals of 3G-SDI (3Gbps transmission rate serial digital signal) and DVI (Digital Video Interface). Background technique [0002] At present, in the field of radio and television in my country, the trend of 3G-SDI signal application has become more and more clear, and equipment providers can race against time to launch their own equipment compatible with 3G-SDI signals. In application, various equipment cascades often have some unexpected error effects. These phenomena are often fleeting and cannot be captured, resulting in the inability to analyze the cause of the problem and thus fail to solve the problem normally. The maintenance personnel of the equipment are not the suppliers of the equipment, let alone the R&D personnel of the equipment. When a problem is found, they cannot ...
