Abstract: A method for preparing content for watermarking is disclosed. The content is available in different versions on a server for at least a client and the different versions of the content are subdivided into temporally aligned chunks. For each version of the content, candidate locations for watermarking are obtained. A watermark payload bit insertion rate is determined according to a minimum path. Watermark embedding metadata is generated for each version of the content such that the watermark payload bit insertion rate is the same. A device for implementing the method and a non-transitory program storage device are also disclosed.

Abstract: A method for preparing a content for watermarking is disclosed, wherein the content is available in different versions on a server for at least a client and wherein the different versions of the content are subdivided into temporally aligned chunks. The method comprises obtaining, for each version of the content, candidate locations for watermarking; determining a watermark payload bit insertion rate according to a minimum path, wherein the minimum path comprises, for all sets of temporally aligned chunks, the chunks with the smallest number of candidate locations; and generating watermark embedding metadata for each version of the content such that the watermark payload bit insertion rate is the same. A device for implementing the method and a non-transitory program storage device are also disclosed.
