摘要： A digital watermark information detection method for detecting information inserted as a digital watermark from contents has a step of converting the contents into a predetermined specified format and a step of trying to detect information from the converted contents. When a plurality of specified formats are defined in advance and detection of the information from the converted contents fails, the contents is converted into another specified format and the information detection is retried.

摘要： It is an object of the present invention to more strongly protect data to be distributed from being illegally plagiarized, and further, to add an electronic watermark function necessary to protect the copyright to all reproduction means apparatuses. In order to achieve the above-described objects, according to the present invention, data targeted for protection is encrypted, and an encryption key required for decrypting this encrypted data and reproduction control data for protecting the copyright are embedded in encrypted data through the use of the electronic watermark. Thus, when reproducing the data, the electronic watermark is detected, and the encryption key required for decrypting the cryptogram and the reproduction control data for protecting the copyright are restored. Through the use of the restored encryption key, the cryptogram is decrypted. Thus, through the use of the reproduction control data restored, the reproduction of the data targeted for protection is controlled.

摘要： In an electronic watermark embedding technique, even when image data compression such as MPEG2 compression is conducted for image data of an image including a watermark while keeping deterioration of picture quality within an allowed range, the electronic watermark is kept retained. A watermark embedding operation and an MPEG2 encoding operation as well as a watermark detecting operation are cooperatively executed. Specifically, in the WM embedding operation, information regarding an operation state of an MPEG2 encoder, particularly, information regarding an amount of data is received. According to the received information of data, parameters such as the total amount of the watermark to be embedded, strength thereof, and an embedding position thereof are controlled.

摘要： The controller includes a deflection signal generator for generating a deflection signal for causing the electron beam to deflect and perform overwriting so that a beam spot of the electron beam follows the translation of the substrate over a period during which the substrate is rotated over a predetermined number of overwriting cycles; and a data output unit for outputting the drawing data, wherein, the deflection signal generator generates a deflection adjustment signal for irradiating the electron beam at a starting position for drawing a concentric circle to be subsequently overwritten after a predetermined deflection adjustment period has elapsed since overwriting of concentric circles based on the drawing data has completed.

摘要： Recording capacity per layer is detected from a disc and bit allocation of wobble addresses in a conventional optical disc and bit allocation in a high-density optical disc are controlled selectively to detect physical position addresses on the disc. Address detection can be performed for two kinds of discs which are equal in structure of addresses embedded in wobbles but different in bit allocation of addresses.
