Title: Digital watermark processor, its insertion method and its detection method
Inventor: MASE KATSUYOSHI
IPC: H04N1/387
Filed: 2000-05-26
Abstract: PROBLEM TO BE SOLVED: To insert plural kinds of digital watermark information into electronic data, and to detect digital watermark information from the electronic data into which plural kinds of digital watermark information is inserted. SOLUTION: When plural kinds of digital watermark information is to be inserted into electric data, an image time stamp detector 3 extracts time stamps corresponding to each image data in the image data stream. Digital watermark insertion circuit 8 determines the kind of digital watermark information to be inserted based on the extracted time stamp, and inserts that kind of digital watermark information into each image data. This information is synthesized with voice data at Mixer circuit 9. When digital watermark information is to be detected from the electronic data, a digital watermark detector 4 determines the kind of digital watermark information to be detected and detects the digital watermark information. Data for display is created by the detected digital watermark information and by the image data.
