To keep their content safe from piracy, video content owners must understand the watermarking process.

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. Digital rights management (DRM) technology is a priority for Hollywood studios, which create high-quality video content and distribute it around the world. 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. In order to keep video assets safe, security experts use a variety of watermarking techniques. A content decryption module is required by the browser because it must first decrypt encrypted video before it can be played (CDM). Without this, the video can’t be viewed in its entirety in the DRM system. Encrypted media extensions (EMEs), which are browser APIs, are used to communicate between the browser and the CDM. 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.

Taking care of the original 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 CDN receives the compressed watermarking data that has been embedded into the original frames.

As a result of this approach, watermarks can be inserted into the video during compression. When the video frame is modified, the programme inserts unique information into the unused space. It safeguards the video asset’s code rate. Since watermark extraction can be done in real time while decoding, this method becomes extremely useful.

Extracting the watermark is critical. Piracy is a serious problem, and it needs to be dealt with quickly. The method used to embed watermars has an impact on the extraction procedure.
