Forensic Video Watermarking to Prevent Piracy of OTT Content Explained in Simple Steps

Copyright infringement can be deterred with the use of forensic video watermarking, which enables content owners to find the source of the leak and correct the problem before it spreads to other users. DRM-protected content is more secure because of the watermark that is added to the media object.

With pre-packaging solutions and integrated content distribution, video watermarking service providers make it possible to deliver premium video streams in DASH/HLS formats. Customized options are available for both live and video-on-demand services.

Both scenarios require watermark embedding, so let’s walk through the process step-by-by-step.

In the case of a live stream, a single publishing point consumes two similar but individually watermarked content streams. The watermarking service’s embedder module receives a live stream from the encoder and processes it. Using this module, samples can be marked with an A/B watermark and the outputs corresponding to that are generated. In some cases, the embedder adds padding to ensure that samples from both A/B streams are the same size.

The encoder sends data in segments, and the output segments should be the same length as the encoder’s segments. The default for DASH is to set the parameter for HLS output to ensure that the encoder sends equal-length segments. DRM protected content must also be configured in the packager for this process to work.

A/B versions of content can be created by watermarking and then repackaging them using the service’s pre-package option. Create a server manifest to finish configuring the stream. Keeping the A/B versions’ names consistent with the personalizer package requires that each track have a distinct name. There are no additional costs associated with this video watermarking service, and it is flexible enough to accommodate personalised streaming services for end-users. encoding algorithm as the input to the watermarking process. This embedder module generates byte watermarked video streams, each with a unique identifier, as the output. Inconspicuous and dispersed throughout the video stream, these watermarks are virtually undetectable to the naked eye.

The video watermarking service must be seamlessly integrated into the entire content distribution process. End-to-end DRM content protection is ensured throughout the entire user experience. The embedder module uses a pre-processed file that usually has a predetermined encoding algorithm as the input to the watermarking process. This embedder module generates byte watermarked video streams, each with a unique identifier, as the output. Inconspicuous and dispersed throughout the video stream, these watermarks are virtually undetectable to the naked eye.

One manifest file with the.ism extension can contain all the bit rate renditions in files that are watermarked with progressive bit rates. In the root directory of your local server, these should be located and accessible via a streampath and manifest extension path. Both scenarios require watermark embedding, so let’s walk through the process step-by-by-step.
