A method for controlling a reproduction device which reproduces data held in a USB device connected to a USB terminal is provided. The method includes: detecting that the USB device is connected to the USB terminal; transmitting a call to the USB device, if the connection of the USB device is detected; detecting, during a first waiting time, a response from the USB device to the call transmitted to the USB device; detecting, during a second waiting time, different from the first waiting time, a response from the USB device to the call transmitted to the USB device, if the response from the USB device is not detected during the first waiting time; and reproducing the data held in the USB device, if the response from the USB device is detected during the first waiting time or during the second waiting time.

A gain setting method for setting a gain in an amplifier that amplifies signals obtained from an optical disk, which includes: a measuring step for measuring an output level of the amplifier; and a gain setting step for setting the gain as the value of the target level/output level, when the measured output level is in a range of 1/N times and N times (N is an integer of 2 or larger) with respect to the preset target level.

Disclosed is a playback device capable of audio playback with little or no interruption. Yet, there is no need of increasing the memory capacity of the playback device and sacrificing the usability of the playback device. The playback device stores, to its internal memory, identification information of audio data stored on a recording medium such as an optical disc, and specifying information specifying the storage location of the identification information. The playback device sequentially stores the audio data to a remaining area of the memory. The audio data stored in the memory is supplied for playback.

To discriminate a disk in a short time, a calculating partmeasures an amplitude of one of a focus error signal and a tracking error signal, which are output from a differential signal generating part, several times, and outputs the measured amplitudes to a controller. The controllercompares the input amplitudes with threshold values stored in a memory, respectively, and determines whether or not an amplification gain of one of the focus error signal and the tracking error signal is changed. If it is determined that the amplification gain of one of the focus error signal and the tracking error signal is changed, the controllerchanges the amplification gain of one of the focus error signal and the tracking error signal to an amplification gain represented by one of the threshold values and discriminates the kind of an optical disk based on the changed amplification gain.

A audio processing apparatus capable of judging and correcting volume levels of audio data, with a level judgment thinning controller for thinning the frequency of the level judgments provided therein, can reduce a throughput and implement the level judgments and corrections in the case of multi-channel input audio data maintaining the original number of the channels thereof. The audio processing apparatus, with a plurality of level judging devices and level correcting devices further provided therein, can implement audio processings at optional settings in response to users' preferences. The present invention thereby provides the capability of judging and correcting levels of the multi-channel audio data while maintaining the original number of the channels thereof.

The multimedia data decoder includes a decoding section and a control section. The decoding section for decoding coded data in a bit stream has a function to detect a synchronous word from the bit stream, analyze decoding information following the synchronous word and extract specific option designating information from the decoding information. The control section determines whether or not the option designating information extracted by the decoding section has any out-of-standard value, that is, any value that is not defined by a standard. If the option designating information has any out-of-standard data, the control section controls the decoding section so as to replace the out-of-standard value with a value defined by the standard and conduct a decoding process. For this purpose, the control section applies replacement information to the decoding section. Accordingly, decoded data is obtained even if the decoding information has an out-of-standard value.

A digital signal processor includes a coded audio data generation unit for generating coded audio data; an audio data generation unit for generating audio data; a signal switching unit for outputting one of the coded audio data and the audio data respectively supplied from the coded audio data generation unit and the audio data generation unit, and switching the output between these data; and a signal switching control unit for detecting the periodicity of the coded audio data outputted from the coded audio data generation unit, and controlling the signal switching unit so as to switch the output at the boundary of periods of the coded audio data.

Digital signal processor

A digital circuit, which avoids problems in LSIs including erroneous operation even when noise is superposed on a clock signal, is provided. A frequency divider divides the frequency of a first clock signal to generate a raw clock signal. A first flip-flop synchronizes the raw clock signal with a second clock signal. A second flip-flop synchronizes an output signal of the first flip-flop with the first clock signal and outputs the synchronized signal as a reproduced clock signal.
