Abstract: 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.

Abstract: 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.

Abstract: A selectable operation amount is set as a threshold value according to an input operation amount, where if a determination value obtained by adding the input operation amount and an integrated operation amount or an output error accumulated value is greater than or equal to the threshold value, the threshold value is selected as the output operation amount, and if the determination value is not greater than or equal to the threshold value, a selectable output operation amount close to the threshold value is selected, and the ON/OFF control is performed with the selected output operation amount, while the selected output operation amount is subtracted from the determination value to correct the integrated operation amount, so that the input operation can be substantially output even if it takes an operation amount other than the selectable operation amount values.
