RECORDING MEDIUM AND SOUND DECODER FOR DECODING SOUND DATA RECORDED THEREON

摘要

PROBLEM TO BE SOLVED: To make a reproduction side normally reproducible even when a multi-channel selectively transmitted by compression or non-compression, and down-mix of the reproduction side is selectively permitted or inhibited. SOLUTION: ATSI contains a 1st identifier presenting whether or not multi- channel data in an audio packet are compressed, and a 2nd identifier whether or not it is allowed or inhibited to down-mix the multi-channel data into 2- channel stereo.
