Audio Data Packet Format and Decoding Method thereof and Method for Correcting Mobile Communication Terminal Codec Setup Error and Mobile Communication Terminal Performance Same

摘要

Disclosed is an audio data packet format for transmitting an IYIPEG-4 HE-AAC frame via a voice channel of a mobile communication network, a method for decoding the audio data packet format, a method for correcting a codec setup error by identifying a codec used to encode sound source data inserted into a data field of voice slot data, based on the sequence number of the voice slot data, and correcting the codec setup error when a codec set up in a mobile communication terminal is different from the codec used to encode the sound source data, and a mobile communication terminal adapted to correct a codec setup error.
