摘要： The input signal of one of the plural channels is converted by a converting circuit into frequency components which are separated into tonal components and noise components in a signal comment separating circuit. The tonal components and the signal components are encoded by a tonal component encoding circuit and a noise component encoding circuit, respectively. The amount of bytes allocated to the noise components in the respective channels is determined by a byte allocation circuit based upon time changes of the sum of the scale factors of the respective channels.

摘要： In this invention, an approach is employed to carry out blocking of an input signal to transform the blocked signals into spectrum signals to divide the spectrum signals into a plurality of units to normalize them thereafter to implement variable length encoding to all or a portion of the spectrum signals to output the variable-length encoded signals along with normalization coefficient and the number of re-quantization bits of each unit, wherein an upper limit is provided with respect to the number of bits per each block of a signal to be encoded and outputted to compulsorily change, in a block for which the number of bits above the upper limit is required, normalization coefficient of at least one unit thereafter to re-quantize and entropy-encode a corresponding signal to output the encoded spectrum signal, thereby permitting hardware scale to be smaller as compared to the conventional apparatus without depending upon unevenness of the number of bits by variable length encoding. In addition, efficient encoding and decoding can be carried out in a form such that influence from a viewpoint of the hearing sense is small.

摘要： A signal encoding method and apparatus by which a high encoding efficiency may be achieved by encoding tonal components of plural channels by exploiting channel-to-channel characteristics. The encoding of separately encoding first signals of plural channels is selectively changed over to the encoding of encoding the first signals of plural channels in common or vice versa depending on the results of detection of characteristics of the first signals of plural channels. The compression ratio may be improved if the first signals are encoded in common, while ill effects due to encoding in common may be avoided by separately encoding the first signals of plural channels.

摘要： In this invention, in the case of transforming an input waveform signal into frequency components at a frequency component decomposing circuit 701 to allow the frequency components from the frequency component decomposing circuit 701 to undergo normalization and quantization, and encoding at a normalizing/quantizing circuit 702 and a code train generating circuit 703, operation of QMF is omitted with respect to bands of the unnecessary side by a processing band control circuit 704, whereby the number of operations necessary for filter operation is reduced so that high speed operation can be carried out and work area necessary for filter operation can be reduced. Namely, this invention can simplify filter operation in accordance with, e.g., required quality of reproduction signal, and can reduce circuit scale of encoding unit/decoding unit.

摘要： An information encoding method and apparatus, an information decoding method and apparatus and an information transmission method in which encoding and decoding with higher efficiency and higher sound quality may be achieved by gain control in meeting with the degree of amplitude changes in the attack portion and the pre-echo may be prevented from occurring. Gain control and gain control compensation operations are performed by applying a gain control function with a smaller gain control quantity and by applying a gain control function with a larger gain control quantity to a signal waveform portion having a level just ahead of an attack portion higher than a pre-set level and to a signal waveform portion having an extremely low level just ahead of the attack portion, respectively. By changing the gain control quantity depending on the degree of amplitude changes at the attack portion of the signal waveform, the pre-echo is prevented from occurring, while the efficiency is prevented from being lowered due to energy diffusion in the frequency domain.

摘要： The present invention includes an encoding and decoding apparatus and method where there is used a transform processing to allow a waveform element of a corresponding block to interfere with waveform elements of blocks adjoining in both directions at the time of inverse transform processing as in the case of, e.g., MDCT, to compose a waveform signal, amplifying processing in encoding and corresponding correction processing in decoding can be carried out without inconsistency between blocks. Thus, occurrence of pre-echo can be prevented by simple configuration by using spectrum transform processing of high encoding efficiency.

In the data encoding apparatus for encoding and subsequently variable length encoding the input data, spectral data obtained on orthogonal transform coding are routed to a block floating circuit 403 for normalization and re-quantized in a quantization circuit 404 depending on the bit allocation number information from a bit allocation calculating circuit 406 so as to be then variable length encoded by an encoding circuit 407 and outputted at an output terminal 408.

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.
