    • The present invention relates to a signal processing apparatus and a signal processing method, an encoder and an encoding method, a decoder and a decoding method, and a program capable of reproducing music signal having a better sound quality by expansion of frequency band.A high band decoding circuit decodes high band encoded data outputs a coefficient table having coefficients for the respective high band sub-bands, which are specified by a coefficient index obtained as a result of decoding. A decoding high band sub-band power calculation circuit calculates decoded high band sub-band powers for the respective high band sub-bands based on low band signals and the coefficient table, and a decoded high band signal production unit produces decoded high band signals from these decoded high band sub-band powers. At this time, an extension and reduction unit newly produces or deletes coefficients of the coefficient table for the respective sub-bands to correspond to the number of sub-bands of the calculated decoded high band sub-band powers, thereby to extend or reduce the coefficient table. The present invention can be applied to a decoder.

    • In a transmission apparatus, a comparison unit provides threshold values associated with an amount of data indicating a signal frequency, and compares an input parameter obtained by cumulatively adding a correction amount to the parameter with the threshold values. When the input parameter is within a range defined by the threshold values, a correction unit outputs a value of the input parameter. When the input parameter is out of the defined range, the correction unit outputs an associated one of the threshold values so as to eliminate an amount exceeding or falling short of the defined range, to thereby correct the input parameter. An addition unit detects the correction amount which is an amount of the immediately preceding value of the input parameter exceeding or falling short of the defined range, and cumulatively adds the correction amount to the input parameter used for the comparison of this time.
    • 在发送装置中,比较单元提供与指示信号频率的数据量相关联的阈值,并将通过将该修正量累加到该参数而获得的输入参数与阈值进行比较。 当输入参数在由阈值定义的范围内时,校正单元输出输入参数的值。 当输入参数超出限定范围时,校正单元输出相关联的一个阈值,以便消除超过或超出限定范围的量,从而校正输入参数。 加法单元检测作为输入参数的紧接在前的值的量的校正量超过或者不超过限定范围,并且将校正量累加到用于此时间的比较的输入参数。

    • The encoding apparatus generates information for generating a high quality high frequency sub-band signal when expanding the frequency band at the decoding apparatus. A signal encoding apparatus divides an input time series signal into a plurality of sub-bands and encodes a low frequency sub-band signal to generate encoded data of the low frequency sub-band signal. Concurrently, it compares the frequency amplitude peak of the new high frequency sub-band signal generated from the low frequency sub-band signal and the original high frequency sub-band signal and generates frequency amplitude peak information of the high frequency sub-band signal. Similarly, it compares the gain of the new high frequency sub-band signal generated by using the low frequency sub-band signal and the original high frequency sub-band signal and generates gain information of the high frequency sub-band signal. Subsequently, the signal encoding apparatus multiplexes the encoded data of the low frequency sub-band signal, the frequency amplitude peak information of the high frequency sub-band signal and the gain information of the high frequency sub-band signal and outputs compressed data.
