ABSTRACT:
In order to discourage compression of video and other visual image signal data that accompanies unauthorized reproduction, distribution and storage of such data, the signal data is modified in a manner to be essentially imperceptible but which, when compressed and then decompressed, causes the signal quality to be unacceptable. In one approach, the visual signal is modified directly. In another approach, the signal is first transformed into the same domain where a compression-decompression algorithm encodes and decodes the data, and then the transformed signal is modified so that the quality of the visual signal when decompressed and displayed is unacceptably degraded.
