A transmission device configured to transmit a transmission bit string which is an arrangement of a unit bit string of multiple N bits includes: a conversion unit configured to convert the unit bit string into a converted bit string in accordance with a conversion table obtained by obtaining an error rate wherein a k'th bit out of the N bits is in error; obtaining an error expectancy which is an expectancy that a significant bit of the N bits in the unit bit string will err; and creating a conversion table that correlates the unit bit string and a converted bit string obtained by converting the insignificant bit of the unit bit string to a smallest error expectancy bit pattern which is a bit pattern that minimizes the error expectancy of the multiple bit patterns; and a transmission unit configured to transmit the converted bit string.

In a sound-source signal separating method, a target sound-source signal in an input audio signal is enhanced, the input audio signal being from a mixture of acoustic signals from a plurality of sound sources picked up by a plurality of sound pickup devices. The pitch of the target sound-source signal in the input audio signal is detected, and the target sound-source signal is separated from the input audio signal based on the detected pitch and the enhanced sound-source signal.

Speech likeliness or a degree of speech is determined with a simple configuration or with a small amount of processing, and speech parts are separated from an input sound signal. The input sound signal is subjected to a waveform slicing process in frame units. The increase and decrease rate of a half wavelength in the frame is computed. The rate of a zero cross in the frame is computed. The increase and decrease rate of a half wavelength is computed by determining the rate of the portion where the upward half-wavelength or the downward half-wavelength of the waveform of the input sound signal changes to increase and decrease alternately or to decrease and increase alternately. The degree of speech is determined using each rate. Speech processing for separating or accentuating/attenuating speech and background noise in accordance with the degree of speech is performed on the sound signal for each frame.

Corresponding to the compared results of threshold values of uniformly random numbers supplied from a uniformly random number generator and pixel values of an original picture signal, each pixel value of the original picture signal is encoded. The resultant encoded picture signal is transmitted. When a decoding apparatus receives transmission data, the decoding apparatus cumulates encoded values of the transmission data for each pixel value, counts the number of cumulation times, and decodes the cumulated encoded values for each pixel value of the original picture signal corresponding to the number of cumulation times.
