Abstract: There is provided an audio encoding device capable of effectively encoding stereo audio in audio encoding having monaural-stereo scalable configuration. In this device, a correlation degree comparison unit (304) calculates correlation in a first channel (correlation degree between the past signal and the current signal in the first channel) from the first channel audio signal and calculates correlation in a second channel (correlation degree between the past signal and the current signal in the second channel) from the second channel audio signal. The correlation in the first channel is compared to the correlation in the second channel. A channel having the greater correlation is selected. According to the selection result of a correlation comparison unit (304), a selection unit (305) selects the first channel prediction signal outputted from a first channel prediction unit (307) or the first channel prediction signal outputted from a first channel signal generation unit (311) and outputs the selected signal to a subtractor (303) and a first channel prediction residual signal encoding unit (308).

Abstract: A scalable encoding device is capable of improving quality of a decoded signal without increasing an encoding amount and compensating data with a sufficient quality upon data loss. An extension layer bit distribution calculator calculates a bit distribution of a quality improving encoding data and compensation encoding data in the extension layer according to an audio mode of the input signal. An extension layer encoder generates quality improving encoding data according to the specified number of bits. A compensation information encoder extracts a part of core layer encoding data and makes it as compensation encoding data for the core layer. An extension layer encoded data generator multiplexes the extension layer bit distribution information, the compensation encoding data, and the quality improving encoding data so as to obtain extension layer encoding data.

Abstract: When front side members are bent by a front-rear-directional collision of a vehicle, the front side members come in surface, not point, contact with an adjacent member in the vehicle by a contact surface formed at a contact portion. Accordingly, the front-rear-directional collision load is stably transmitted to a member, such as an adjacent engine, such that it is possible to efficiently improve the effect of distributing and reducing the load in a collision. Further, since the bent front side members stably come in surface, not point, contact with the adjacent member, such as the engine in the vehicle, it is possible to decrease the possibility of unexpected fracturing of the front side members.

Abstract: A light diffusing element diffuses light output from an output facet of an optical fiber that enters the light diffusing element at a first end and outputting the diffused light from a second end. The light diffusing element is equipped with a semireflective surface for reflecting a portion of the light, provided at a predetermined portion of the light diffusing element corresponding to the core of the output facet. The semireflective surface intersects at least with the optical axis of the optical fiber. Thereby, propagation of light in directions away from the optical axis of the optical fiber can be promoted during the step of reflecting the portion of the light that enters the light diffusing element.

Abstract: A prediction performance between individual channels of a stereo signal is improved to improve a sound quality of a decoded signal. A first low pass filter LPF interrupts a high-range component of a first channel signal S1, and outputs a first low-range component S1′. A second low pass filter LPF interrupts a high-range component of a second channel signal S2, and outputs a second low-range component S2′. A predictor predicts the S2′ from the S1′, and outputs a prediction parameter composed of a delay time difference t and an amplitude ratio g. first channel encoder encodes the S1. A prediction parameter encoder encodes the prediction parameter. The encoded parameters of the encoded parameter of the S1 and the prediction parameter are then outputted.
