    摘要： A long-term prediction coding and decoding method and apparatus are described in which an error signal sample is obtained by subtracting from a current sample of an input sample time-series signal a multiplication result obtained by multiplying a past sample which is a predetermined time lag older than the current sample of the input sample time-series signal, by a multiplier. There are four possible methods for outputting parameters of a quantized multiplier p' and time lag τ as follows: 1) To output p' and τ once in the frame; 2) to output the quantized multiplier p' in each sub-frame; 3) to output the time lag τ in each sub-frame; 4) to output p' and τ in each sub-frame. In any of the above cases, the parameters are outputted in coded form.

    摘要： An object of the present invention is to efficiently perform weighted difference coding of two or more signals. Determination is made as to which of independent coding and weighted difference coding is to be used for each channel so that the total energy of the channel signals and weighted difference signals is minimized. A weighted difference signal is generated on the basis of the determination and a reference signal (parent) and a weight is generated as auxiliary codes, the difference signal is treated as an input channel signal, and the process of coding determination and difference signal and auxiliary code generation is repeated. The difference signal generated at the last iteration of the process and a signal to be coded by independent coding are compressive coded and the auxiliary codes generated at the iterations of the process are coded and outputted.
