Abstract: There are provided a decoding device and method, a program recording medium, and a program capable of improving the performance of decoding of a modulated code which has been encoded according to a variable length table. A 17PP-SISO decoding section (181) uses the Viterbi decoding algorithm and the BCJR decoding algorithm according to the 17PP encoding table (201) and the trellis expression expressed by a path 1-to-1 corresponding to each state transition of the entire encoding process, thereby SISO-decoding the signal from a PR-SISO decoding section (81) and supplying the SISO-decoded signal to a turbo decoding section (84) via a deinterleaver (83). The turbo decoding section (84) executes turbo decoding processing for the output from the 17PP-SISO decoding section (181). The present invention can be applied to a recording/reproduction device for recording and reproducing a signal onto/from a recording medium such as a high-density optical disc.

Abstract: An acoustic signal reproducing apparatus for reproducing acoustic signals by headphone devices (2) is disclosed. The left channel and right channel acoustic signals are provided by a device (23) for processing the acoustic signals with constant transmission characteristics from an imaginary sound source to both of the listener's ears. The left channel and right channel acoustic signals, processed in this manner by the device (23), are provided by an acoustic signal processing device (21) with a level difference and time difference consistent with changes in orientation of the listener's head (M).

Abstract: In the audio signal reproducing apparatus, information on the transfer characteristics representative of the transfer characteristics from virtual sound sources to both ears of a listener in at least a first quadrant of the rotational angular position of the head M of the listener is stored in storing means 22. The transfer characteristics in rotational angular position of the head M represented by detection outputs from detecting means 5L, 5R and 13 for detecting the rotational angle position depending upon the movement of the head of the listener are formed based upon the transfer characteristics information of at least the first quadrant stored in the storing means and left and right channel audio signals are processed by audio signal processing means 23 for achieving a proper binaural reproduction relative to the virtual sound sources. Also in the audio signal processing apparatus of the present invention, information on the transfer characteristics from virtual sound sources to both ears of a listener for each given rotational angle depending upon the movement of the head M of the listener is stored in storing means 62. The rotational angular position of the head of the listener is detected by detecting means 45L, 45R and 53 at a solution higher than that of the information of the transfer characteristics stored in said storing means. The information on at least two transfer characteristics in the vicinity of the rotational angular position represented by the detection outputs from detecting means is read from the storing means. The information on the transfer characteristics in the rotational angular position of the head represented by the detection output is interpolation operated by interpolation operating means 61. Based upon the information on the transfer characteristics determined by the interpolation operation means, left and right channel audio signals are processed by audio signal processing means 63 for achieving a proper binaural reproduction relative to the virtual sound sources.

Abstract: There are provided a decoding method, a decoding device, and a program capable of suppressing the operation frequency to a range capable of sufficient realization of it and easily performing control of memory access while suppressing the circuit size. LDPC (Low Density Parity Check) code is decoded by using a conversion inspection matrix obtained one or both of the row replacement and the column replacement for the inspection matrix of elements of the LDPC code. In this case, the conversion inspection matrix can be expressed by a combination of a plurality of constituting matrixes such as a unit matrix of P × P, a quasi-unit matrix in which one or more components 1 of the unit matrix have become 0, a shift matrix in which a unit matrix or a quasi-unit matrix is cyclically shifted, a sum matrix which is a sum of at least two of the unit matrix, the quasi-unit matrix, and the shift matrix, or 0 matrix of P × P. A check node calculation section (302) simultaneously performs calculation of P check nodes while a variable node calculation section (304) simultaneously performs calculation of P variable nodes.
