摘要： A signal processing device and method for performing a code string transform by transforming a time series signal with a frequency band from 0 to 20 kHz from a coding system into another, wherein the arithmetic operations of MDCT and IMDCT with a limited frequency band from 0 to 15 kHz are carried out at high speed by performing computations using an FFT operation with a short tap length in the IMDCT processing operation. This allows a reduced work area and a higher speed for arithmetic operations by reducing the number of multiplications and additions when performing MDCT operations, IMDCT operation and/or transforming code strings between different coding system.

摘要： To make it possible to provide high-quality music signal regardless of the advertising voice superimposing position, an encrypted pure music signal input through a transmission medium and an unencrypted advertising voice signal are separated by a signal string separation section. A signal transform and combining section decodes the encrypted pure music signal and combines the decoded music signal with the advertising voice signal into a resultant signal of the music and advertising voice signals, then outputs the resultant signal to a code string combining section, which then combines the encrypted pure music signal and the resultant signal of the music and advertising voice signals and supplies the result to a recording section for recording the result on a magneto-optic disc.

摘要： When sample data is played back, audio guide data G1 and G2 and subsequent frame data are played back based on usage license information L1 contained in the sample data. When high-quality data is generated, the audio guide data G1 and G2 and the usage license information L1 are overwritten based on usage license information L2 contained in additional data. When the high-quality data is played back, audio guide data G1′ and G2′ and subsequent frame data are played back based on usage license information L3. A user is then able to identify the playback status of the sample data or high-quality data by listening to an audio guide.

摘要： It is intended to remove a risk of illegal high quality restoration while enabling trial viewing of contents such as music, to make it possible to reproduce contents with high quality by acquiring a relatively small amount of data, and to make it possible to implement hardware at a lower cost. To generate trial listening data containing dummy data, a pseudo random number R is generated first. A remainder r of R divided by 128 is calculated. The remainder r is coded and incorporated into high sound quality restoration data. A bandwidth limitation region of trial listening data is replaced by dummy data starting from its rth bit. As a result, the head position of the dummy data in the trial listening data varies frame by frame, whereby the safety of the trial listening data can be increased.

摘要： An original code string is decomposed into preview data (trial data) and high-quality data in a code-string decomposer. The high-quality data is separated into first data having an exactly or almost regular pattern and second data other than the first data by a high-quality data separator 1882. The second data is encrypted. The first data is not encrypted, or is encrypted by an encryption process other than that used for the second data. With this arrangement, important data is prevented from being deciphered.

摘要： A first audio signal is generated from a number of stereo input channels (such as a left and a right channel). A signal level that corresponds to one of the plurality of input channels and another signal level from another of the plurality of input channels are determined. A second audio signal is selected on the basis of the signal levels such that the second audio signal is selected from the group consisting of the one input channel, the other input channel, and a signal generated from the number of input channels that is different than the first audio signal. The first audio signal and the selected second audio signal are separately coded.
