Abstract:
Detection of faults in a transmitted signal stream occurs by recovering, from the information stream, a water mark embedded in the stream prior to transmission. The embedded watermark has data characteristic of stream quality. Thereafter, the at least one watermark property is analyzed to detect faults in the received information stream.
