Abstract: When an input signal is signal-converted and is output, the copyright of a signal to be signal-converted is reliably protected. In an additional information detection/determination section, digital watermark information, CGMS information, etc., which are superposed on or added to an input luminance signal, are detected, and it is determined whether or not a signal which is to be signal-converted in a signal conversion section should be output on the basis of the detected additional information. When additional information for prohibiting or limiting copying has been superposed on or added to the input luminance signal, a switching circuit for output control is turned off so that the signal which is signal-converted in the signal conversion section is not output to the outside.

Abstract: The pattern (pattern characteristic quantity) extracted from the pattern image carried by original printing paper is stored on the original printing paper and the validity of the original printing paper is verified according to the pattern stored on code-added printing paper at the time of copying the printed contents of the code-added printing paper so as to determine if the code-added printing paper is truly original or not by means of the pattern carried by the printing paper itself. Therefore, it is possible to prevent unauthorized copying with ease without using any special paper and hence appropriately protect the printed contents.

Abstract: A calculator system for performing duplication of contents does not necessarily perform screening, i.e., electronic watermark detection, rather, contents copy control information can be obtained otherwise. For example, in the event of copying a CD regarding which it is known beforehand that there is no electronic watermark inserted in the contents, the electronic watermark detection processing itself can be skipped as long as the CD can be confirmed to be such, thereby reducing the amount of time necessary for copying. Electronic watermark inspecting processing with heavy computation loads is performed vicariously for judging whether or not duplication of contents is permissible.

Abstract: A first p+-type region on a surface of a photodiode unit is formed over a region from a surface of the photodiode unit through a surface of a signal charge read-out unit until reaching the charge transfer unit. Also, the following structure is adapted: the structure in which a boundary between the first p+-type region and a p++-type region is not on a same plane with a boundary of an n-type impurity region which forms the photodiode unit on a side of the signal charge read-out unit. Further, a second p+-type region is formed between the first p+-type region and the p++-type region on the surface of the photodiode unit. The second p+-type region has an impurity concentration between the impurity concentrations of the first p+-type region and the p++-type region.

Abstract: A copy control technique using digital watermark information, which makes it possible to prevent a content from being erroneously subjected to a copy control process according to wrong copy control information at a content-to-content transition. Copy control information in the form of digital watermark information (WM) is embedded in a content to control copying of the content in accordance with the embedded copy control information. A content-to-content transition is detected by detecting a change in a content state, such as a change in image luminance, or a change in copy control information associated with a content, or is detected on the basis of a flag, a descriptor, or channel switching. In response to detection of a content-to-content transition, a reset signal is output to a WM analyzer to reset current copy control information into a “undefined” state, so that copy control is performed in a mode such as a copy-free mode assigned to the “undefined” state.

Abstract: An information processing apparatus is connectable to a bus that is connected to a further apparatus. A detecting circuit detects whether the bus is connected to the information processing apparatus. When the detecting circuit detects that the bus is connected to the information processing apparatus, a control circuit controls a power supply circuit such that the power supply circuit provides power to a further circuit. When the detecting circuit detects that the bus is not connected to the information processing apparatus, the control circuit controls the power supply circuit such that the power supply circuit does not provide the power to the further circuit.

Abstract: In a recording system having an accounting function, in recording a copy target information signal onto a recording medium, an identification signal for identifying the contents of the information signal is saved in a recording machine, and at the time of copy, the saved identification signal and the identification signal of an information signal to be newly recorded are compared with each other to discriminate whether or not copy and recording of the same information signal was carried out by the recording machine in the past, thereby discriminating whether or not recording should be permitted on condition that accounting is carried out, on the basis of the result of comparison. If the information signal was copied in the past, copy and recording is permitted on condition that accounting is carried out, thereby preventing unlimited first-generation copy.
