Over-the-top (OTT) services like Netflix and Amazon Prime must now employ multiple tactics to combat premium video content piracy. Players on the over-the-the-top (OTT) network risk losing money if illegal hackers succeed in stealing their data. A top priority for Hollywood studios that create and distribute high-quality video content is DRM technology. In the event of a successful piracy attack, premium video content owners want to include information about the video’s owner, user, and device in the video file itself during playback.
The DRM approach and video watermarking technology can be used in tandem to protect OTT content, both of which are typically provided as software as a service by the same vendor, known as multi-DRM SaaS vendors.
The vendor uses an SDK to embed binary data into the video asset as part of the forensic watermarking technology. Each user’s copyright and other personal data is stored in these files. DRM watermarks are enhanced by the vendor’s watermarking algorithm, which adds barely perceptible but extremely robust watermarks that a pirate cannot easily alter. Even if a pirate repeatedly encodes and decodes the watermarked video asset, the data’s robustness protects it.
There are a variety of methods for embedding video watermarks in DRM protected content. Many different watermarking techniques are employed by security experts when it comes to protecting video assets. The browser necessitates the use of a content decryption module in order to view encrypted video (CDM). Without this, the video can’t be viewed in its entirety in the DRM system. Communication between the browser and CDM is accomplished through the use of browser APIs known as encrypted media extensions (EMEs). An HTML5 player is used in web browsers to display the OTT content. EMEs enable browsers to make use of HTML5. Video content can be streamed without the need to download extensions like Adobe Flash or Microsoft Silverlight using a combination of the CDM and an HTML5 browser.
Reuse of redundant spaces in the compressed video stream is an important step in the post-compression stage of the forensic watermarking process. Forensic watermarks can be inserted into these spaces after compression has been completed to the satisfaction of the editor. Algorithms and codecs must be kept separate in order for the watermarked asset to perform as efficiently as possible.
Maintaining the source video Before the original video is compressed, this algorithm is applied. The video asset is viewed by the algorithm as a sequence of still images called frames, each of which contributes to the video’s overall effect at a specific frame rate. The compressed watermarking data embedded in the original frames is delivered to the CDN.
Because of this method, watermarks can be added to videos as they are compressed. When the video frame is modified, the programme inserts unique information into the unused space. The code rate of the video asset is kept safe. Since watermark extraction can be done in real time while decoding, this method becomes extremely useful.
It’s critical to get the watermark out. Piracy is a serious problem, and it needs to be dealt with quickly. The extraction procedure is affected by the embedding method.
