Watermark Embedding

In order to embed a watermark in the original video, a preprocessing operation is required in the content encoding process. A watermarked value (0 and 1) is inserted in the original uncompressed video frame to generate a watermarked frame and output as two sets of encoded video.

The inserted watermark value is encrypted using a secret key unique to each content service provider, and can not be extracted from the outside arbitrarily.

The watermark embedding method can be selected from CLI embedder, embedder library or watermarking packaging service depending on the customer’s environment.
