    Abstract: An apparatus for embedding a watermark into contents data includes a parameter converting device for converting a parameter of first contents data to generate second contents data. A mixing device operates for embedding parameter information into the second contents data as watermark information. The parameter information represents a condition of the conversion of the parameter by the parameter converting device. The watermark information may include copyright information.

    Abstract: Additional information is generated for each of unit recording blocks in a recording medium. The generated additional information is recorded on a first area in the corresponding unit recording block. A piece of file data is recorded on a second area in each of the unit recording blocks. The second area differs from the first area. The additional information for each of the unit recording blocks includes 1) file identification information for identifying the file data, 2) next-sector address information indicating an address of a unit recording block following the present unit recording block, and 3) first-sector identification information indicating whether or not the present unit recording block is first one of the unit recording blocks assigned to the file data. The additional information may further include effective-data identification information indicating whether a piece of the file data recorded on the present unit recording block is effective or ineffective.

    Abstract: Digital image data is divided, per frame, into “N” fields. “N/m” combinations of imperceptible codes are produced, each combination having “m” codes given by an inverse of a function giving an identification code with the “m” codes as variables. “N” and “m” are an integer of 2 or more and “m” is given by dividing “N” by an integer. The combinations are embedded into the data to embed the “m” codes of each combination into the data in “m” fields according to a rule of positional correspondence to give correlation among “m” fields in “N” fields. The data is divided into “N” fields and the codes are extracted therefrom and combined into the combinations according to the rule. An operation is conducted based on the function. It is determined that the data has not been tampered with only when the operation gives the identification code for each combination.

    Abstract translation: 数字图像数据按帧划分成“N”字段。 产生不可知代码的“N / m”组合，每个组合具有由给出具有“m”个代码的识别码作为变量的函数的反函数给出的“m”个代码。 “N”和“m”是2以上的整数，并且“m”通过将“N”除以整数来给出。 这些组合被嵌入到数据中，以根据位置对应规则将每个组合的“m”个代码嵌入到“m”字段中的数据中，以给出“N”字段中的“m”字段之间的相关性。 数据被划分为“N”个字段，并且根据规则将代码从其中提取并组合成组合。 基于功能进行操作。 只有当操作给出每个组合的识别码时，确定数据没有被篡改。

    Abstract: Address information is recorded on an optical recording medium having groove portions and land portions. The groove portions form a recording track and are spaced at a constant track pitch. The land portions extend between the groove portions. The address information represents the positions of places on the optical recording medium. The recording of the address information is implemented as follows. The address information is converted into words of a self-synchronizable code. The words of the self-synchronizable code are subjected to bi-phase modulation to generate a bi-phase-modulation-result signal. The bi-phase modulation causes frequency modulation. Thus, the bi-phase-modulation-result signal is a frequency-modulation-result signal. The frequency-modulation-result signal is recorded on at least one sides of the groove portions to form wobble of the recording track.
