Over-the-top (OTT) content can be successfully watermarked through the utilisation of session-based video watermarking, which is extremely effective.

The expansion in the availability of over-the-top (OTT) and video-on-demand (VOD) content has resulted in an increase in the demand for watermarking solutions. These solutions are intended to prevent the content from being used or disseminated illegally, and they have contributed to this spike in demand. As a result of this, there is a necessity for techniques that are able to recognise certain user accounts or streaming sessions in order to implement watermark detection. Watermark detection is essential for discovering leakers and taking the right steps against them. The demand cannot be met with procedures that are considered to be “standard” for watermarking.

At this point in the calculation, the technique of session-based video watermarking enters into action. Session-based watermarking is being examined as a potential solution to the problem known as the “analogue hole,” which has become more widespread as a result of the availability of HD monitors and cameras.

In order to develop a session-based watermark, you will need to produce two unique variations of the same piece of material (called A and B variants). Through the use of adaptive bitrate distribution, the files are segmented into smaller parts, and the playouts are organised according to a specified pattern of As and Bs. In the process of revealing the session identity, the one-of-a-kind A/B sequence is taken into consideration. This helps to ensure that the correct session is revealed. Each chunk that is utilised originates from either Track A or Track B. Once these chunks have been utilised, they are subsequently divided into session-based manifests along with descriptions of the various chunks and combinations that can be utilised. When things are handled in such a way, each session has the potential to have its own manifest that is founded on the binary representation of the information.

There is no longer a requirement for any client-side third-party integrations when only two copies of the material are cached using a content delivery network (CDN). This is because the server-side manifests already have all of the necessary information, which is the reason why this is the case. As a result of this, it is no longer need to make or store as many versions of the content as there are users on a content-sharing platform because there is no longer a demand to do so. As a result of this, it is no longer essential to do so. Session-based watermarks are difficult to erase or tamper with within a system that has been effectively developed and implemented. This is the case even if the user attempts to re-digitize, re-compress, or trim the item in question. This is the case regardless of whether the user changes the asset to an analogue format or not.

By utilising session-based watermarking, producers and streaming services are able to shield themselves against a broad variety of threats, including collusion and the manipulation of playlists, which might compromise their security. Using server-side watermarking, which eliminates the requirement for device integration as a prerequisite, it is possible to add an additional layer of protection to DRM protected content on a number of devices. This additional layer of protection can be applied to a number of different devices.

These solutions are intended to prevent the content from being used or disseminated illegally, and they have contributed to this spike in demand. As a result of this, there is a necessity for techniques that are able to recognise certain user accounts or streaming sessions in order to implement watermark detection. Watermark detection is essential for discovering leakers and taking the right steps against them. The demand cannot be met with procedures that are considered to be “standard” for watermarking.
