Embodiment Construction

[0031] Attached below Figure 1~2 The present invention will be further described in detail with specific embodiments.

[0032] The video output control method based on content detection provided by the present invention comprises the following steps:

[0033] Step 1: Get the audio and video information of the input video stream; that is, get the input audio and video signal through the audio and video input terminal (analog or digital audio and video interface).

[0034] Step 2: Extract key features of audio and video.

[0035] Step 3: judging whether the input video is a bad video;

[0036] Step 4: When the video is a bad video, close the video output stream and give an alarm.

[0037] In the above step 1, after obtaining the audio and video information of the input video stream, it is necessary to first determine whether the audio and video information is analog information or digital information, and if it is analog information, first convert the analog information into...

Abstract

The invention provides a video output control method based on content detection. The method comprises the following steps of acquiring audio and video information of an input video stream; extracting key features of the audio and video; judging whether the input video is a porn video; when the video is the porn video, closing the video output stream and giving an alarm. Meanwhile the invention provides a device which applies the above method, comprising a video input module, used for acquiring the input audio and video information, and converting the audio and video information into digital information if the acquired input audio and video are analog information; a video content detection module; a wireless data transmission module; a video output control module; and a power supply module. The method can filter the video information output from the multimedia terminal device in real time, and immediately give an alarm and close the video stream when finding the porn video, thus being capable of avoiding baneful influence caused by long-time spreading and diffusion of the porn audio and video.

Description

technical field [0001] The invention relates to the field of pattern recognition and information dissemination, in particular to the problem of multimedia terminal sensitive video filtering. Background technique [0002] With the development of multimedia terminals and network technology, outdoor new media such as outdoor video and mobile media terminals have become an important way of information dissemination. Media terminals using LED / LCD screens can be seen in squares, business districts, buildings, buses, subways, etc. They provide a variety of communication methods with rich colors and content, and have a wide coverage and great influence. Advantages, and has become an indispensable and important means in the field of modern information dissemination. [0003] However, due to poor technology or supervision, there have been many times in the society that pornographic videos are played on outdoor screens, and pornographic or violent videos are broadcast live on the Inte...
