A method of detecting and extracting a watermark (digital watermarking) in a digital signal. The watermark is composed by the repetition of elementary components of a load to be transmitted. At least one repetition of an elementary component in the digital signal is detected. At least one quality attribute is assigned to each repetition of at least one elementary component. The repetitions of an elementary component are sorted according to a function of the quality attributes of these repetitions. Certain repetitions, dubbed individualities, of an elementary component are selected. The selected repetitions are fused.

Method of detecting and extracting a watermark

An apparatus for serving audiovisual content comprises a parser, a decompression module, a packaging module, and a transmission module. The parser is adapted to receive an image data file and separate the image data file into a first compressed image component and a second compressed image component. The decompression module is coupled to the parser and adapted to decompress the first compressed image component into an uncompressed image component. The packaging module is coupled to the decompression module and adapted to package the uncompressed image component into a data stream having plural data fields arranged in a format defined in accordance with an industry-accepted standard and the second compressed image component into unused ones of said plural data fields, for transmission over a data interface. The transmission module is coupled to the packaging module and adapted to transmit the data stream over the data interface.
