Abstract
A method of processing a video fragment into two or more variants of the video fragment, each variant having a different watermark, the method comprising: fragmenting a video content into a sequence of fragments; watermarking a plurality of the fragments to create two or more variants of each of the plurality of fragments, wherein the two or more variants of one fragment are watermarked using different watermarks; adjusting the length of the two or more variants for at least one of the fragments to a same adjusted length, wherein the adjusted length is indicative of a temporal position of the two or more variants of the at least one of the fragments compared to variants of other fragments in the sequence of fragments.

A method of processing a video fragment of a video content into two or more variants of the video fragment, the method comprising:
- fragmenting the video content into a sequence of fragments;
- watermarking a plurality of the fragments to create two or more variants of each of the plurality of fragments, wherein the two or more variants of one fragment are watermarked using different watermarks;
- adjusting a length of the two or more variants for at least one of the fragments to a same adjusted length, wherein the adjusted length is indicative of a temporal position of the two or more variants of the at least one of the fragments compared to variants of other fragments in a sequence of watermarked fragments, the temporal position being defined as a position within a limited number of possible positions for the watermarked fragments in the video content.
