Abstract:
1. A method of decoding an audio signal by a decoder, the method comprising: receiving, by the decoder, the audio signal including a block of audio data partitioned into N sub-blocks; restoring, by the decoder, a plurality of code parameters s( decoding, by the decoder, the N sub-blocks using the restored code parameters; receiving, by the decoder, the audio signal having a plurality of random access units, each random access unit including a number of frames and at least one of the frames being a random access frame, each random access frame being a frame encoded such that previous frames are not necessary to decode the random access frame; reading, by the decoder, location information from the audio signal, the location information indicating whether random access unit size information is stored or not in the audio signal, and if the random access unit size information is stored in the audio signal, the location information further indicating a location where the random access unit size information is stored in the audio signal; reading, by the decoder, the random access unit size information according to the location information, the random access unit size information indicating a distance between two adjacent random access frames in bytes; and decoding, by the decoder, the random access units based on the random access unit size information.
