摘要： The invention relates to a method for decoding a watermark embedded in a video comprising blocks of samples representative of the video comprising the steps of determining in the video a location of a watermarked block; determining a location for each reference block among a plurality of reference blocks wherein a reference block is associated to a watermark value among a plurality of watermark values; comparing the watermarked block with each reference block; and identifying watermark value for the watermarked block from the results of the plurality of comparison. The method is remarkable in that each reference block is equally located in the video, for instance the pirated video, so that the plurality of comparisons between the watermarked block and each reference block is performed among the same video.

摘要： The invention relates to a method for watermarking at least one timestamp in a set of support data, comprising the following steps for each timestamp: association with the timestamp of the value at a given time of a reference timestamp signal, that is a determinist signal varying over time in a given temporal reference and being written as s(t), wherein t is incremented according to an incrementing step equal to one predetermined time unit; and watermarking of the value in the set of support data. The invention also relates to a corresponding decoding method comprising the following steps: reading, in the set of support data, of at least one value of a phase-shifted timestamp signal, of the same form as the reference timestamp signal but having in relation to this signal an unknown phase shift φ in a given temporal reference, the previous watermarking of each timestamp consisting in a watermarking of the value at a given watermarking time of the reference timestamp signal; estimation of the phase shift φ from the at least one read value of the phase-shifted timestamp signal and from the knowledge of the reference timestamp signal; and for the at least one read value, read at a given time tr, determination of an associated timestamp h associated according to the read time tr and the estimated phase shift φ.
