摘要： A synchronization signal detecting section is internally provided with a stream type counter for counting stream type information output from a header information analyzer and a stream type determining section for instructing, based on a value in the stream type counter, a signal processing section to initiate stream conversion. If the value in the stream type counter reaches a predetermined value, it is determined that the input signal is a stream signal. If the value in the stream type counter does not reach the predetermined value, synchronization signal detection is restarted from the address which is one bit ahead of an address stored in a synchronization address storing section.

摘要： To allow high speed search for audio files described in a play list and to quickly perform reproduction of the audio files according to the play list even when a plurality of audio files are recorded on a recording medium, a matching comparison unit for performing a search for a file name described in the play list from file names included in a file name list is provided in a signal processing circuit for performing processing such as decoding of an audio file. When reproduction using the play list is instructed, respective file numbers of the audio files detected in the search by the matching comparison unit are output to a control circuit.

摘要： An audio processing unit that provides a high-sound-quality reproduction even when a band property of an input encoded signal drops at or below a Nyquist frequency. The audio processing unit has a band-variable bandpass filter 1500; a band determining section 1700 for determining a passband of the band-variable bandpass filter with respect to a band extension component from an extended band generating section 1300 by using decoding information from a decode-processing section 1100 as a band determination information; and a bandpass filter controller 1600 for controlling the passband of the band-variable bandpass filter in accordance with an indication from the band determining section.

摘要： The clock supply device, which supplies a master clock to a stream processing apparatus that processes stream data frame by frame in synchronization with the master clock, includes a clock supply section, a processing amount computation section and a clock control section. The clock supply section supplies a clock having a predetermined frequency to the stream processing apparatus as the master clock. The processing amount computation section computes, at predetermined processing timing in a series of data processing performed for each frame by the stream processing apparatus, a data processing amount accumulated until the processing timing for each frame. The clock control section outputs a control signal according to a comparison result between the computed data processing amount and a predetermined threshold. The clock supply section switches the frequency of the clock supplied to the stream processing apparatus in response to the control signal.
