Abstract: A data stream transmission/reception device manages external devices in at least two groups, assigns independent resources to the groups, and for each group, a connection is made to the assigned hardware resource via a preferentially-used plug. This enables handling a plurality of streams at the same time in the case of being connected to a plurality of conventional external devices that have only one logical plug.

Abstract: In a digital information reproducing apparatus, a digital signal having passed through a band-limited transmission system is waveform-shaped at a threshold level controlled to its optimal value so that the information can be properly read out. The apparatus includes a threshold level control circuit for controlling the threshold level to shape the waveform of the input signal. This threshold level control circuit has a first control circuit for controlling the threshold level with reference to a read clock extracted from the input signal, and a second control circuit for controlling the threshold level of a shaped signal which is obtained by waveform-shaping the input signal so that the DC component of the shaped signal becomes a predetermined value. The control of the threshold level is performed by cooperation of the first and second control circuits. The first control circuit is adapted to control the threshold level in accordance with a difference between the shaped signal obtained by waveform-shaping the input signal and the read-out signal obtained by synchronizing the shaped signal with the read clock. Thus, the threshold level for waveform-shaping a modulated channel code signal can be controlled optimally regardless of whether or not the modulation system is DC-free. The second control circuit serves to prevent a spurious lock of the first control circuit.

Abstract: A virtual RAM read address generating circuit (41) generates a virtual address-on the basis of an output signal of a crystal oscillation circuit (36). A phase comparison circuit (39) which performs phase comparison with a write address, and a spindle control circuit (3) which controls rotation of a disk with reference to outputs of a frequency comparison circuit (38) and the phase comparison circuit (39) are disposed. Therefore, a phase error can be fed back to a spindle motor, thereby preventing linear velocity deviation from occurring in a steady state. By using the thus configured reproducing device, the reproduction quality in the case where a disk wherein recording was performed by the CLV system is reproduced by the variable linear velocity reproduction system is ensured, and both high-speed access and low power consumption are realized.

Abstract: On a liquid crystal panel, plural areas whose number is larger than that of temperature sensors are defined. In a memory, temperature relation information representing a relation between an output value of a temperature sensor and a temperature of each of the plural areas is stored. A controller acquires the output value of the temperature sensor and estimates, based on the temperature relation information and the acquired output value, the temperature of each of the plural areas. According to this configuration, the temperature of each of the plural areas defined on the liquid crystal panel can be obtained with a small number of temperature sensors.
