Abstract
The disclosure relates to processing content with watermarks to generate watermarked versions. In some aspects, each version may be different. Groups of fragments may be combined to generate a unique stream by pulling fragments from two or more of the groups of fragments. Further, fragmenting may be performed before watermarking, and fragments may be pulled and watermarked upon request.
