Abstract: Degrees of association between categories of songs (hereinafter, song categories) corresponding to information showing advertisement distribution target categories and distribution object advertisements are determined in advance in an advertisement DB. A song categorization module calculates degrees of association between an acoustic feature amount of a song being played (hereinafter, current song) and feature amounts of the song categories, and a song-related distribution object advertisement candidate group extraction module determines a distribution object advertisement corresponding to a song category with a high degree of association is determined as a distribution object advertisement. An advertisement presentation module provides information on the distribution object advertisement to a user along with current song information.

Abstract: In a parallel multi-value neural network having a main neural network 16 and a sub neural network 18 coupled with the main neural network 16 in parallel for an input signal, the main neural network 16 is trained with a training input signal by using a main multi-value teacher signal, and the sub neural network is successively trained with the training input signal by using multi-value errors between a multi-value output signal of the main neural network 16 derived through a multi-value threshold means 17 and the main multi-value teacher signal, so as to compensate the multi-value errors involved in the multi-value output signal of the main neural network 16 by the multi-value output signal of the sub neural network 18 derived through a multi-value threshold means 19. A desired multi-value output signal of the parallel multi-value neural network 15 is obtained by adding in modulo the multi-value output signals of both the neural networks through a multi-value modulo adder 20.

Abstract: In an echo canceller used in a four-wire digital telephone circuit, a main echo estimator (21) and a sub echo estimator (22) are coupled with a receive path for measuring a receive signal, and subtracters (25, 26) are inserted in a transmit path for cancelling an echo component in a transmit signal. Filter coefficients in said estimators (21, 22) are adaptively controlled by a convergence control processor (24). The main echo estimator has a small step gain for updating filter coefficients so that the response to an echo is slow, while the sub echo estimator (22) has a large step gain and quick response for an echo. An register accumulator (23) is provided so that the filter coefficients by the sub echo estimator (22) are selectively accumulated on the related filter coefficients in the main echo estimator (21) according to operation modes, ordinary mode, accumulating mode, and reset mode.

Abstract: In an echo canceller having PCM interfaces used in a PCM telephone circuit, an echo estimator (65) is coupled with a receive path through a linear code converter (632) for measuring a linear receive input signal, and a subtracter (7) is inserted after a linear code converter (631) in a transmit path for cancelling an echo component in a linear transmit input signal. The same procedure as that in a conventional echo canceller is performed in a divergent situation in the echo estimator (65) in which a large step gain is assigned, and in a convergent situation in the echo estimator (65) in which a relatively small step gain is assigned, a non-linear quantization processor (27,271) is inserted between the subtracter (7) and the echo estimator (65). The non-linear quantization processor (27,271) produces a new echo estimate containing a quantization noise, based on an echo estimate which is derived from the echo estimator (65).
