Abstract: PROBLEM TO BE SOLVED: To improve the proof quality of image data and to obtain an electronic watermark embedding technique with little waste. SOLUTION: Embedding data to be embedded as an electronic watermark are obtained and the embedding data are successively repeated without space at least three times to form packed data. Redundant bits of a fixed length which are used for correcting errors of information bits are added right after the information bits which are formed by subsectioning the packed data into bits of a fixed length for forming actual embedding information.

Filed: 2000-06-23
Abstract: PROBLEM TO BE SOLVED: To provide a digital modulation transmission apparatus with which the analysis and adjustment of a cause to a defect of transmission apparatus. SOLUTION: In the transmitter of the OFDM system employing a modulation system (synchronization modulation system) corresponding to the synchronization detection, a 3rd signal is modulated by the DBPSK in addition to a main information code and a pilot signal modulated by the BPSK, a signal point 'Δ(delta)' of the 3rd signal is taken in a direction of the Q axis and a signal point ' (a)' of a pilot signal is taken in a direction of the I axis. The transmitter conducting modulation by the synchronization modulation system is adjusted by displaying the arrangement of signal points of the pilot signal being a reference signal at demodulation and a signal modulated by an information code.  Even in the case of the 3rd signal modulated by the DBPSK not in a direct relation to the synchronization modulation system, when the position of the signal point is overlapping the position of the pilot signal, it makes adjustments rather difficult. However, according to this invention, the signal point of the pilot signal and that of the 3rd signal are observed in a completely separated state, and hence the adjustment is facilitated.
