A video filtering device and method, and video display system

Abstract

The invention provides video filtering equipment, a video filtering device, and a video display system. The equipment comprises a signal input interface, a data collector, a processor and a signal output interface, wherein the signal input interface is connected with a video source terminal and the data collector, the processor is connected with the data collector and the signal output interface,and the signal output interface is connected with the display terminal. The embodiment of the invention provides the independent video filtering equipment arranged between the video source terminal and the display terminal, for recognizing and intercepting bad information in a video before playing in real time, so that the bad information can be filtered, the effect of real-time online visual protection is achieved, and management on video playing is improved; the equipment is convenient to use, and has the characteristic of plug and play, subsequent overhauling, maintenance and upgrade of theequipment are facilitated, and the equipment does not occupy resources of the video source terminal and does not occupy resources of the display terminal either when being used for filtering the video.

Description

technical field [0001] The present invention relates to the technical field of information monitoring equipment, in particular, to a video filtering equipment and method, and a video display system. Background technique [0002] At present, with the rapid development of the electronic information society, in people's daily life, various display devices can be seen everywhere as public electronic screens, in commercial buildings, office buildings, schools, hospitals, stadiums, stations, airports and other places All kinds of electronic screens can be seen everywhere. The public electronic screens are mainly used for policy promotion, business promotion, information dissemination, teaching demonstration, etc. Obviously, public electronic screens have become an important source of public visual information in people's daily life. The establishment of public electronic screens facilitates people's lives, increases publicity channels, and enables people to get in touch with fresh...

Problems solved by technology

The establishment of public electronic screens facilitates people's lives, increases publicity channels, and enables people to get in touch with fresh information, but it also brings potential risks of visual pollution

[0003] For example, recent misbroadcast accidents of pornography on public electronic screens have occurred frequently, causing bad social impact. Typical incidents include: On September 5, 2014, indecent videos were played on the monitors in the cafeteria of the Experimental School Affiliated to Peking University in Zhuhai City, Guangdong; on June 23, 2015, Heilongjiang Pornographic video was played on the outdoor electronic screen of Yunhua Plaza in Mudanjiang City; pornographic video was played on the outdoor electronic screen of Wandi Plaza in Lishui City, Zhejiang Province on August 5, 2015; pornographic video was played on the electronic screen in the atrium on the first floor of Wanda Plaza in Bengbu City, Anhui Province on February 12, 2016 ; On March 17, 2016, pornographic videos were played on the outdoor electronic screen of a real estate under construction in Xi'an, Shaanxi; Incidents of broadcasting pornographic, violent and other harmful information on public electronic screens occur frequently

[0004] At present, the protection of bad information on public electronic screens mainly relies on the management software and management system of video uploads. Through the management software and the system, the staff can confirm the video when updating the video, which can prevent the video containing bad information from being misunderstood to a certain extent. Play, but there are the following limitations: First: it only protects against one factor at the source of video playback, and the risks at the source of video playback are various, including U disk virus, network intrusion and other factors. Misplay of bad information caused by source factors is hard to prevent; second: based on the protection of bad information by managers, there are human factors involved, which cannot be considered, and it is still possible that videos containing bad information may be misplayed due to insufficient human control; third: added The difficulty of uploading video source updates

[0005] In the process of realizing the present invention, the inventors found that there are at least the following problems in the related technologies: In the related technologies, the management and control of managers is mainly used to avoid the playback of videos containing bad information, and there may be human factors involved or other uncontrollable factors that may cause The misplay of bad information videos was not controlled by technical means, and the final prevention was not done at the moment before the video was played, resulting in poor controllability of the playback of bad information videos
