发明名称 SUB-BAND VOICE CODEC WITH MULTI-STAGE CODEBOOKS AND REDUNDANT CODING TECHNIQUE FIELD
摘要 <P>PROBLEM TO BE SOLVED: To improve quality of speech derived from a codec such as a real time codec. <P>SOLUTION: Techniques and tools related to coding and decoding of audio information are described. For example, redundant coded information for decoding a coded unit includes parameters for a codebook stage to be used in decoding a current coded unit only if a previous coded unit is not available. As another example, coded audio units include a field indicating whether the each coded unit includes main encoded information representing a segment of an audio signal, and whether the coded unit includes the redundant coded information for use in decoding the main encoded information. <P>COPYRIGHT: (C)2012,JPO&INPIT
