Live and audio-visual content piracy costs creators and distributors of original content a lot of money and time. If you want to stop the illegal streaming of live content, you need to find and stop the unauthorised streamers quickly, typically within 15 minutes. As 4K UHD and HDR content become more widely used, watermarking will need to be able to process the video data in real time while the video is playing back.

Digital output protection outside of the security perimeter provided by traditional techniques such as DRM protected content and CAS may not be effective in the fight against piracy.. This means that the content must be identified outside of the client’s video terminal in order to be tracked. In this case, the use of transactional watermarking becomes necessary. The ID of the source is encoded in the video pixels, and any streamed content can be traced back to the source of infringement or insensitive subscribers. video watermarking solutions that protect live-streamed content must allow licence holders to disrupt viewing within minutes of streaming by detecting and decoding watermarks in real time. Since “non-blind” approaches require a comparison with an original unmarked video, it is necessary to remove the watermarks directly from the video in order to quickly identify pirated content.

It is possible to watermark image sequences that record a 3D scene and extract the watermark from any rendered image generated for any arbitrary view angle, as opposed to the first two methods, which only  protect the watermark information for the two key components of 3D scene representation (geometry and texture). If you’re using dynamic watermarking, you may embed information on the video asset while it’s being played back at the user’s end, such as the user’s email, date  and time of watching, their IP address, or even their business logo. Because of their dynamic nature, they provide additional protection for confidential content that  is not intended to be shared or altered. DAI (dynamic ad insertion) is also activated via dynamic watermarking in order to optimise addressable ad income.

Content infringers typically need time and stability to plan hacking, trial-and-error strategies, and develop reverse-engineering techniques. Using dynamic watermarking, content creators can quickly and easily change and adapt watermarks, even modifying them for each live event if needed.

Because dynamic watermarks are software-based, they can easily reach a wide range of devices that sports fans watch matches on. They are also undetectable to the viewer and pirates, and can be quickly scaled up because they are based on the cloud. In addition, they are able to operate on low video resolutions to identify the source of piracy, as well as on high video resolutions. For each viewer, dynamic watermarks appear at random points in the video and are personalised to their preferences. Sharing or recording the video makes the piracy source obvious. In addition, they are difficult to remove without compromising the quality of the video clip, both of which make it unsuitable for further use in the future. During illegal acquisition (camera recording, screencasting, etc.) and storage, some dynamic watermarks are also kept (re-encoding, aspect ratio change, etc.).
