    摘要： A communication system includes: a transmitter adapted to transmit a synchronizing clock and serial data synchronous with the synchronizing clock over a line at low amplitude; and a receiver adapted to receive the serial data and synchronizing clock from the transmitter. The receiver includes an amplifier adapted to amplify the received synchronizing clock of low amplitude to restore the clock to its original amplitude, a latched comparator adapted to latch the received serial data in synchronism with a reproduction clock, and a phase-locked circuit.

    摘要： Regularity information such as time codes embedded preliminarily through an electronic watermark is detected from a predetermined number of pieces of continuous frame data of video content through the electronic watermark. In the case where the electronic watermark is not detected from the predetermined number of pieces of continuous frame data, a non-detection count is calculated, and falsification of the predetermined number of pieces of frame data is determined on the basis of the detected regularity information and the non-detection count. Accordingly, falsification such as deletion, addition, and replacement of video content is detected with high accuracy using the electronic watermark.

    摘要： The problem to be solved is to allow anyone other than the contents license owner to acquire a right usage opportunity of contents while the fraud in the contents can be detected. To solve this problem, a contents ID, distribution media information specifying the distribution media of the contents, and identification information containing distribution period information specifying the distribution period of the contents are attached to the contents body When a contents acceptance module 140 receives the contents data, an acquisition pattern recognition unit 142 recognizes the acquisition pattern information of the contents data. A identification information extraction module 154 of a contents validity determination module 150 extracts identification information from the contents data. A validity determination unit 153 compares the condition specified by this identification information with the contents acquisition media and the acquisition period indicated by the acquisition pattern information and if the acquisition pattern information satisfies the condition specified by the identification information, the contents data is stored in the contents-for-distribution file 126. Additionally, if the contents are determined to be illegal a deletion request is sent to the requestor.

    摘要： At least one kind of control signal concerning control of contents, added to specific locations inside contents data, is detected as first control information, and at the same time, at least one kind of control information concerning control of contents, embedded inside the contents data by a digital watermark, is detected as second control information. Consistency between the first control information as detected, and the second control information as detected is determined and on the basis of results of the determination, the control of the contents is executed. Thus, it is possible to reduce a possibility of the contents being improperly copied, thereby enabling the control with assurance of still higher safety.

    摘要： A power switch and connector that are conventionally included in a body are formed in spaces created at the outer ends of the shafts of hinges other than the body and a display, whereby the body is thinned. Electronic device comprises a body, a display, and a hinge that joins the body and display so that they can be freely opened or closed. A power switch is formed at an end of the shaft of the hinge. Furthermore, the electronic device comprises the body, the display, and another hinge that joins the body and display so that they can be freely opened or closed. A port of a connector opens at an end of the shaft of the hinge.

    摘要： An information presentation apparatus includes an information organization structure editing unit, a search condition creating unit, an information collection unit, and a collection result joining unit. The editing unit prompts a user to enter plural terms and one or more relations among said terms and store them as an information organization structure. The search condition creating unit creates a search condition of information from the terms and the relations among the terms stored in the information organization structure. The information collection unit searches information storage by using the created search condition and collect location information of the data meeting the search condition. The collection result joining unit visually joins the terms and the relations among the terms stored in the information organization structure with the location information of the searched data and displays the joined result.
