摘要： PROBLEM TO BE SOLVED: To provide an encoder maximizing calculation accuracy while ensuring real time performance. SOLUTION: An audio signal is inputted to reset a timer (S1). The frequency of the audio signal is divided into 32 frequency bands (S2) so as to calculate a scale factor (S3). Then a masking level where a processing time is fluctuated based on a signal is calculated (S41) and whether or not a timer value is higher than a reference value is judged (S42). When judged to be higher than the reference value, masking level conversion processing in the step S43 is conducted. When not, the processing of the step S44 is conducted. In this case, the processing in the step S43 is conducted at low accuracy but its processing time is short. On the other hand, the processing of the step S44 is conducted at high accuracy but its processing time is long.

摘要： PROBLEM TO BE SOLVED: To efficiently encode multichannel data by adjusting the bits to be allocated to the channels when entropically coding the multichannel data.
SOLUTION: The multichannel coding device 1 has n pieces of encoders 10
n corresponding to the audio data of n channels, and a channel bit allocation section 30 to allocate the bits number B
n each channel can use depending on the tentative bits number b
n determined from each encoder 10
n . Each encoder 10
n makes entropy encoding from the tentative quantizing step and outputs b
n obtained by summing all the bit lengths of each coding unit, then adjusts the bit length by revising the quantizing step depending on the B
n thus supplied. Or, the channel bit allocation section 30 distributes all the usable number of bits S as the B
n determined according to the ratio of each b
n to the total b
n .

摘要： PROBLEM TO BE SOLVED: To effectively detect a quantization value used for last encoding in a quantization arithmetic circuit for encoding data. SOLUTION: The quantization value in the last decoding is detected by using a decimal part generated in the quantization process of MPEG, etc. Namely, in the case of simple dubbing, in the case of the quantization value in the last decoding or a quantization value being its measure, a DCT coefficient can be divided, thereby the accumulated of its decimal part becomes '0'. Consequently, by selecting the largest quantization value in the quantization values the accumulated of the decimal part is '0', the quantization value in the last decoding can be detected. In order to improve detecting precision, quantization arithmetic processing is performed with all the AC coefficients except the DC component of all the DCT blocks of Y/Cb/Cr as objects by each macro block, and the decimal part obtained as the result of it is accumulated by the portion of 504 coefficient to be judged.

摘要： PROBLEM TO BE SOLVED: To realize various functions related to the changing of normalized information. SOLUTION: Encoded data are supplied to a computing element 710 through an input terminal 707. The element 710 adds numerical data supplied from a normalized information changing circuit 790 to scale factor information in the encoded data. Output of the element 710 is supplied to an adaptive bit assignment decoding circuit 706. The circuit 706 conducts a process on the supplied signals in order to release bit assignment. Inverse orthogonal converting circuits 703, 704 and 705 convert the output of the circuit 706 into the signals on a time axis. The outputs of the circuits 703 to 705 are synthesized by band synthesis filters 701 and 702 to yield full band signals. By operating the scale factor information by the operation of the element 710, a normalized information changing circuit 709 conducts level adjustment for every 2dB, for example, for reproduced data.
