摘要： According to one embodiment, since key information is written after a drive unit and host unit are assembled into a player, it is not necessary to manage, in the assembled player, the correspondence in secret key information between the drive unit and host unit. Further, in the player, even if, for example, the drive unit must be exchanged for another, encrypted key data can be shared simply by writing another key data item.

摘要： A digital filter having a characteristic expressed by a rational function executes a signal processing in a predetermined sequence in accordance with a pre-emphasis mode or de-emphasis mode. A first digital filter has a characteristic expressed by a denominator polynomial of the rational function and processes an input signal according to this characteristic to produce a first process signal. A second digital filter has a characteristic expressed by a numerator polynomial of the rational function and processes an input signal according to this characteristic to produce a second process signal. A mode selector selects one of the pre-emphasis and de-emphasis modes. A first switch supplies the input signal to the first digital filter in accordance with the pre-emphasis mode and supplies the second process signal from the second digital filter to the first digital filter in accordance with the de-emphasis mode. A second switch supplies the first process signal from the first digital filter to the second digital filter in accordance with the pre-emphasis mode and supplies the input signal to the second digital filter in accordance with the de-emphasis mode.

摘要： A repeater comprises an EDID memory to store a control data and a memory control unit. The memory control unit is configured to make access to the EDID memory to read the control data therefrom, store the read control data into the EDID memory and, when access is made to the EDID memory by the set-top box, transfer the control data stored in the EDID memory to the set-top box. In this case, the memory control unit outputs an inhibiting signal to a set-top box to inhibit it from making access to the EDID memory until the completion of an operation of storing the control data from the EDID memory in the set-top box into the EDID memory in the repeater.

摘要： Digital servo apparatus includes a counter adapted to count inputted reference clock pulses to display time data. The output of the counter is latched by a first tacho pulse (controlled signal) to a first latch circuit and the contents of the first latch circuit is transferred by a second tacho pulse to the second latch circuit and the present count data of the counter is latched to the first latch circuit. A discrimination circuit is adapted to discriminate whether or not a control signal is within a predetermined control amount, based on time difference data latched to the first and second latch circuits, and deliver an output signal corresponding to a predetermined control amount based on the result of discrimination.
