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： 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.

摘要： A digital input signal is compressed to provide a compressed output signal in a manner which prevents pre-echo, a common defect of data compressors. The digital input signal is divided in time into frames, and into at least one block of data in each frame. The frames include a past frame preceding a present frame. Block floating is applied to the data in the block in each frame. Quantizing bits are adaptively allocated to the data in the block in the present frame in response to the block in the past frame. Finally, the resulting quantized data is added to the compressed output signal. In a first variation, a signal energy or an allowable noise level is determined for the block in each frame. A word length is determined for the block in each frame in response to the determined signal energy or allowable noise level of the block. The quantizing bits are allocated to the data in the block in the present frame in response to the word length for the block in the past frame. In a second variation, a signal energy in the block in each frame is determined, and quantizing bits are adaptively allocated to the data in the block in the present frame in response to an interpolation between the signal energy for the block in the present frame and for the block in the past frame.

摘要： In a data transfer system, when transferring data which has been transferred to a storage in a PC, to a mobile terminal connected to the PC, the PC acquires the file format of the data and the file format which can be processed by the mobile terminal and determines whether the conversion of the file format is necessary. When the conversion of the file format is necessary, the PC issues a request for a conversion to a format converter. The format converter acquires data from the PC and transfers the data back to the PC while performing conversion. The PC transfers the converted data to the mobile terminal.

摘要： Efficiently encoded signals wherein the compression ration can be high without a corresponding degradation of signal quality. The range of values of subband-based signal components for quantization to zero, to which a short codelength is given, is set so as to be larger. Consequently the ratio of the subband-based signal components quantized to values of a shorter codelength will become higher than if the subband-based signal components are quantized in such a manner as to minimize the total quantization error energy in each frequency band.
