摘要： 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.An encoder sets an interval including 16 frames as interval section to be processed, outputs high band encoded data for obtaining the high band component of an input signal and low band encoded data obtained by encoding the low band signal of the input signal for each section to be processed. In this case, for each frame, a coefficient used in estimation of the high band component is selected and the section to be processed is divided into continuous frame segments including continuous frames from which the coefficient with the same section to be processed is selected. In addition, high band encoded data is produced which includes data including information indicating a length of each continuous frame segment, information indicating the number of continuous frame segments included in the section to be processed and a coefficient index indicating the coefficient selected in each continuous frame segment. The present invention is applicable to the encoder.

摘要： An encoding apparatus that 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. 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.

摘要： In a path status monitoring method and device which can enhance or reduce a band more rapidly, for example, SONET frames FR serially connected over 32 frames to which frame Nos. FN (“0”-“31”)) are assigned are cyclically generated respectively for paths P0-P2 in a cycle TC (=64 ms). After output timing delays TD0-TD2 of the frames FR are shifted by an optimal delay interval D (=21 ms) between the paths P0-P2 based on the number of the paths “3”, the output timing delays TD1 and TD2 are restored by preliminarily obtained transmission delays for the paths P1 and P2 to the path P0. When the frames FR are transmitted through each of the paths P0-P2, statuses (path statuses MST) where a reception fault has occurred in each of the paths P0-P2 are collected to be stored in the frame whose frame No. FN=“0”.
