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： 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.

摘要： An information encoding method for encrypting and encoding information signals, such as PCM audio signals, in which the information signals can be reproduced with low quality even in the absence of the key information for encryption. For carrying out the information encoding method, the input PCM signals are converted by a transform unit into frequency signal components which are encoded by a signal component encoding unit. High frequency range side signal components are sent to an Ex-OR gate to take an Ex-OR of the high frequency range side signal components with a pseudo random bitstring from a pseudo random bitstring generating unit. A codestring generating unit 1606 generates a codestring having the low frequency range side components from a signal component encoding unit and the encrypted high frequency range side components from the Ex-OR gate.

摘要： An apparatus for recording the transfer information transferred to it includes a plurality of recording media for recording the transfer information transferred from an information transfer apparatus, a writing control unit for controlling the writing of the transfer information in the recording media, and a transfer control unit for transmitting the transfer control information and an information transfer request signal to the information transfer apparatus. The transfer control information is the information for determining the transfer sequence of information blocks when the information transfer apparatus transmits the transfer information as the information blocks. The information recording apparatus transmits an information transfer request signal after transmitting the transfer control information to the information transfer apparatus. In this manner, the information recording apparatus receives the transfer information transmitted from the transfer apparatus on a information block basis and records the transfer information on the information block basis on plural recording media. It becomes possible in this manner to record information data on plural recording media not having a uniform writing speed from one recording unit to another, such as a flash memory, by parallel writing in a regular sequence, for enabling highly efficient information transfer by simplified control.

摘要： A signal encoding method and apparatus for encoding an acoustic signal, a recording medium having the encoded signals, a method for transmitting the encoded signals, and a signal decoding apparatus for decoding the encoded signals, are disclosed. With the encoding apparatus, an attack portion detection circuit detects an attack portion of the waveform acoustic signal where the waveform elements of the waveform acoustic signal rise sharply. A gain control circuit controls the gain for waveform elements at least upstream of the attack portion using a gain control amount adaptively selected from plural gain control amounts specified by a pre-set power of 2. A forward orthogonal transform circuit transforms the waveform acoustic signal into plural spectral components. A normalization and encoding circuit normalizes, quantizes and encodes the gain control information an plural spectral components. With the encoding apparatus, the encoding efficiency may be improved without complicating the construction, while the pre-echo may be suppressed effectively.

摘要： In the signal encoding apparatus and the signal encoding method of this invention, normalization coefficients for normalizing a first signal are set to an interval finer than that of normalization coefficients for normalizing a second signal. Namely, accuracy of normalization coefficients at the time of normalizing tone characteristic components is caused to be higher than accuracy of normalization coefficients at the time of normalizing noise characteristic components. Thus, this invention can carry out efficient encoding. In other words, this invention can improve accuracy of encoding of tone characteristic components while suppressing the number of bits necessary for encoding of noise components. As a whole, more efficient encoding can be carried out. Moreover, in the recording medium of this invention, since signals efficiently encoded by the signal encoding apparatus or the signal encoding method of this invention are recorded, recording capacity is effectively utilized. In addition, in the signal decoding apparatus, since signals encoded by the signal encoding apparatus or the signal encoding method of this invention are decoded, signal error in decoding can be reduced.
