Claim Text:
1. An apparatus for decoding a digital audio or a digital speech signal, the apparatus comprising: a processor that: checks a flag indicating whether decoding of a current frame is possible without referring to information on previous frames, from a bitstream including at least one of the digital audio signal and the digital speech signal; determines whether the current frame is encoded in a linear prediction domain (LPD) or a frequency domain (FD), based on a coding mode of the current frame; decodes the current frame without access to the previous frames in the determined domain, when the decoding of the current frame is possible without referring to information on the previous frames, from the flag; decodes the current frame with access to the previous frames in the determined domain, when the decoding of the current frame requires information on the previous frames, from the flag; and generates a reconstructed audio or speech signal from the digital audio signal or the digital speech signal based on the decoded current frame, for audio or speech reproduction.
