摘要： The signal (801) of a first code sequence of a predetermined format a part of which is dummy data is sent to a code sequence rewriting means (1802) through a code sequence decomposing means (1801). The signal (806) of a second code sequence with which the part corresponding to the dummy data in the signal (801) is supplemented is sent to the code sequence rewriting means (1802) through a control means (1805), and the dummy data in the first code sequence is rewritten to the second code sequence. For trial viewing/listening, the signal (802) from the code sequence decomposing means (1801) is selected by means of a selector switch (1808). When the second code sequence (806) is acquired by purchase of a content, the signal (803) from the code sequence rewriting means (1802) is selected. Thus trial viewing/listening of a content such as music free of danger of decryption is possible, and a high-quality content can be reproduced by acquiring a relatively small amount of data.

摘要： A recording area of a recording medium is divided into two regions, one for basic information of a plurality of channels and the other for other additional information. Here, digital audio signals of at least left, center, right, surround left, surround right and sub-woofer channels are recorded as the basic information, and digital audio signals of at least left center and right center channels, their delayed center channels, mixed left channel and mixed right channel are recorded as additional information. When information recorded in either of these regions no longer exists, reproduction is made by using the information of the other region during subsequent reproduction. Further, among the digital audio signals of the eight channels described above (L, LC, C, SW, RC, R, LB, RB), compression/encoding having high auditory sense is applied to signals of the channels having higher auditory influences on the sence of feeling among the six channels (L, LC, C, SW, RC, R) than the other two channels, and encoding having higher compression ratio is applied to the digital audio signals of the two channels (LB, RB). Accordingly, the present invention can apply compression/encoding having high tonal quality to particularly important sounds, and can eliminate the waste of bit allotment quantity (byte allotment quantity).

摘要： The sound quality of inputted signals is changed in accordance with the sense of hearing. The differences of magnitudes of an attribute between frequency components approximately in a critical band are based on auditory characteristics. The frequency components are obtained from acoustic time signal information. The characteristic of this acoustic time signal information is changed by one of the following techniques: (1) the differences of magnitudes of an attribute between frequency components above the threshold of audibility or masking threshold level among the frequency components are changed; (2) the differences of magnitudes of an attribute between frequency components above the higher one of the two thresholds are changed; (3) the differences of magnitudes of an attribute between frequency components in a limited range of level are changed; and the differences of magnitudes of an attribute between frequency components in the approximately critical band obtained from acoustic time signal information having a frequency resolution and a time resolution and containing at least two different frequency components are changed. In such a way, the harmonic relationship between the frequency components in the critical band which is audibly supported is controlled, thus making it possible to adjust the sound quality of speech and acoustic signals to the level useful to a human being.

摘要： A digital signal transmission device in which input digital signals consisting of a train of words that are continuous in time are formed into a block every after a predetermined number of words, and the block is transmitted through the so-called encode filter or a differential processing filter to obtain an estimated error for a signal for each block. The encode filter consists of a plurality of filters made up of an estimating unit of an N-th degree and an estimating unit of a degree smaller than the N-th degree. Maximum absolute values in the blocks produced from the filters or maximum absolute values multiplied by a coefficient are compared with one another, and by selecting a filter which minimizes the value, the input digital signals can be transmitted through filters that provide the greatest efficiency for each of the blocks, e.i., that produce the least estimated errors.

摘要： It has been observed that the S/N ratio of differential-mode PCM and summation-mode PCM with respect to quantization noise is improved at low frequencies and high frequencies, respectively, and consequently the dynamic range thereof is increased. An input signal is divided into blocks of a predetermined number of bits, and, for each block, the one of the general-mode PCM, differential-mode PCM, and summation-mode PCM mode is selected in which adaptive encoding is most efficient, and consequently the quantization noise is smallest, and the input signal data in the mode selected for each block is transmitted together with a mode signal and an adaptive data signal, etc. It has also been observed that the closer to the main signal, the larger the masking effect on the sense of hearing, so that the S/N ratio in terms of the sense of hearing is improved by changing the noise spectrum during digitization to correspond to the spectrum of the input signal.

摘要： A high-efficiency encoding method that distributes variable bits among channels to the samples in the time regions or the frequency regions of a plurality of channels (CH1 to CH8). The high-efficiency encoding method quantizes the bit distribution amount of the channels (CH1, CH3, CH6) that distributes the amount of bits larger than a predetermined reference amount (e.g., 147 kbps) by decomposing it into a first bit distribution amount that does not exceed 147 kbps and a remaining second bit distribution amount (which exceeds 147 kbps). The high-efficiency encoding method makes it possible to reproduce compression signals maintaining high-quality tone by utilizing the bit distribution among the channels as well as to reproduce the signals without deteriorating the quality of tone even in a decoder that distributes the bits in the channels using a bit rate smaller than a predetermined value for each of the channels that are frequently used.

摘要： A multi-channel signal compressor for compressing digital sound signals in the respective channels of a multi-channel sound system. The apparatus comprises a first-stage compression system and a second-stage compression system. In the first-stage compression system, a coupling circuit performs coupling between the digital sound signals of at least two of the channels to generate coupling-processed signals, one for each of the channels. A compressor circuit receives the coupling-processed signals from the coupling circuit and frequency divides each coupling-processed signal into frequency range signals in respective frequency ranges, and compresses the frequency range signals obtained by dividing each coupling-processed signal to generate a first-stage compressed signal. In the second-stage compression system, a determining circuit receives the first-stage compressed signal for each channel from the first-stage compression system and determines an energy for each channel from the first-stage compressed signal of the respective channel. A channel bit apportionment decision circuit operates in response to the determining circuit, and apportions a predetermined number of bits among the channels to apportion a number of bits to each channel. Finally, an additional compressor additionally compresses the first-stage compressed signal of each channel using, for each channel, the number of bits apportioned to the respective channel by the channel bit apportionment decision circuit.

摘要： When a time region sample or a frequency region sample of input signals such as audio signals is quantized, the present invention executes block floating processing of MDCT coefficient as a frequency region sample, for example, then executes quantization to generate a first quantized value, calculates a quantization error between this quantized value and the MDCT coefficient, and quantizes individually this quantization error for each sample to generate a second quantized value and to divide the MDCT coefficient into at least two words. In this way, the present invention can minimize the deterioration of tone quality and can secure backward compatibility.
