摘要： A low-pass filter of over-sampling type oversamples an input digital audio signal T1 and filters and removes the low frequency components of the produced aliasing noise. A spectrum analyzer circuit calculates the spectrum intensity of a predetermined band of an output signal from the low-pass filter. An expanded signal generating circuit generates an expanded signal having frequency components of the output signal from the low-pass filter. A level control circuit controls the level of the expanded signal according to the spectrum analyzer circuit. An adder adds the level-controlled expanded signal to the output signal from the low-pass filter thereby to generate a digital audio signal T2.

摘要： This invention relates to a time code recording and reproducing apparatus for recording and reproducing time codes corresponding to a digital signal. Time code converting means (100) converts a first time code into a second time code. A frame phase which occurs during the recording of input information is determined by frame timing generating means. A phase difference between a frame of the second time code and a recording frame is detected by phase difference detecting means (103). Phase difference correcting means (104) outputs a third time code on the basis of the detected phase difference. The input information is recorded together with the third time code. Thereby, the recording can be performed while the relation of the correspondence between the input information and the time code is held. In addition, the reproduction can be performed.

摘要： A sub-scrambling/descrambling method and device enhances the degree of scrambling of linear PCM data. Data is delimited at predetermined times, and the minimum value of a run is found and used as annex information. The run part is replaced with an arbitrary irreversible random data string, which is processed by a main scrambling device to generate transmission data. After main descrambling of the transmission data, a descrambling device takes out the annex Information and replaces the random data string with a predetermined “0” or “1” run according to the annex information. Thus, the degree of scrambling of linear PCM data is enhanced as much or more than compressed video data.
