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.

The invention relates to a system for detecting a watermark using informed detection. A first signal potentially having a watermark embedded is received (601) as is a second signal corresponding to the original signal. The signals are segmented (605) into symbol segments. For each symbol segment a first characteristic is determined (607) for a first section and a second characteristic is determined (609) for a second section in response to the first and second signals in those sections. Specifically, ratios between average envelopes are determined. Thus, the first and second characteristic is indicative of the variations of the envelope during a watermark symbol.

A sequence of estimated watermark symbols is compared to reference watermark symbols and the presence of a watermark symbol is determined (615) depending on the comparison. The invention is particularly suitable for improved detection of a multiplicative watermark.
