Abstract: The disclosure provides a method of making watermarking data embedded in an Elementary Stream ES accessible to a receiver. The ES comprises video and/or audio data and is to be transmitted as a Packetized Elementary Stream PES in a Transport Stream TS such that the receiver can use the watermarking data to watermark the video and/or audio data in the ES without reconstructing the ES from the TS. The watermarking data identifies one or more watermarking locations in the video and/or audio data in the ES to be modified by the receiver in accordance with the watermarking data. The method comprises determining respective one or more watermarking TS locations in the TS corresponding to the one or more watermarking locations. The method further comprises embedding, in the ES, the watermarking data including watermarking location information identifying the one or more watermarking TS locations, or modifying watermarking data embedded in the ES by adding the watermarking location information.
