Video output device capable of tracking propagating sources

Abstract

The invention discloses a video output device capable of tracking propagating sources, comprising a central processing unit, a network interface module, a memory module, a man-machine interaction module and an audio/video drive module which are respectively connected with the central processing unit, wherein, the central processing unit is provided with a watermark generation unit and a superposition output unit; the watermark generation unit is used for generating watermark data information; and the superposition output unit is used for outputting the watermark data information and video information generated by the watermark generation unit. The video output device capable of tracking the propagating sources of the invention is provided with the watermark generation unit and the superposition output unit, leads that the video information output by the video output device can display or hidden with watermark information when a display terminal plays a video, and extracts watermark information in visual contact or a watermark detection device according to hardware information and user information in the watermark information, thereby positioning the propagating sources thereof, tracking related responsibilities thereof, and maintaining the lawful rights and interests of operators and content providers.

Description

technical field [0001] The invention relates to a video output device, in particular to a video output device which is combined with digital watermarking technology and can trace the transmission source. Background technique [0002] With the increasing maturity and popularity of video capture technology, video signals from video output terminals to display devices can be easily captured and edited. These behaviors will seriously affect the legitimate rights and interests of operators and content providers, and bring illegal content The video dissemination of the video has brought great convenience, and it is difficult to find the source of the dissemination at this time, and it is impossible to trace its legal responsibility. [0003] There are two main protection methods commonly used to prevent the illegal dissemination of video content: [0004] The first type: add a specific LOGO to individual screens in the played video, for example, add the LOGO of the content provid...

AI Technical Summary

Problems solved by technology

The method and device for embedding and extracting the watermark information, as well as the processing system embed the watermark information in the target file, so as to realize the protection of the copyright of the target file, but there are still defects that the source of transmission cannot be found, and the responsibility of the communicator cannot be held accountable.
