APPARATUS AND METHOD FOR FORMATTING, WRITING, AND READING DATA IN MULTI-CHANNEL WRITING

摘要

PURPOSE: An apparatus and a method for formatting, writing, and reading data are provided to easily re-write or read the data of a desired channel by multiplexing various packet data and to read the audio data of multi-channels without synchronous timing control. CONSTITUTION: In a pack, various packets are included. Each packet has a stream ID(Identifier). Audio data of a first channel composed of one or more frames are stored in a first packet. Frames of the audio data of a second channel read simultaneous with the first channel are stored in a second packet. To read the steams wherein the audio data of the first channel are stored, simply the first packet is read by checking the stream ID. A stream for another channel is read by simply extracting a corresponding packet. Since the packets are composed of frames, frame access is performed simply and all streams are synchronized easily.
