摘要

When a frame immediately preceding an encoding target frameto be encoded by a first encoding unit operating under a linearpredictive coding scheme is encoded by a second encoding unitoperating under a coding scheme different from the linear predictivecoding scheme, the encoding target frame can be encoded under thelinear predictive coding scheme by initializing the internal state of thefirst coding unit, Therefore, encoding processing performed under aplurality of coding schemes including the linear predictive codingscheme and a coding scheme different from the linear predictive codingscheme can be realized.
