The invention relates to a system for embedding a watermark into an input media signal. A plurality of sub-band signals of a sub-band encoded input signal is obtained; preferably by de-multiplexing of the corresponding bitstream. A set of sub-band signals is filtered by a sub-band filter (507) which has a response associated with the watermark. The sub-band filter (507) thereby generates a set of filtered sub-band signals which are combined into an output signal having the desired watermark. The output signal is preferably a compressed sub-band bitstream signal. A low complexity approach for embedding a watermark into a media signal by filtering in the sub-band domain is thus achieved obviating the requirement for decoding and re-encoding of the media signal.
