Реферат:	eng: A problem of digital watermarking of a sequence of TV images is considered. An algorithm of embedding of such watermarks based on combining singular decomposition and Haar filtration procedures and a corresponding blind algorithm of watermark retrieval are developed. It is shown that the embedded watermark is stable to basic distortions arising in the TV path, e.g., enhancement of noise, loss of definition, truncation and compression of the multimedia material by MPEG2 or AVC algorithms. Owing to noise-immune encoding, the number of correctly retrieved bits of digital watermarks can reach 100%.
