PROBLEM TO BE SOLVED: To enable a reproduction side to normally make reproduction even if multichannels are selectively transmitted by compression or non-compression and even if down-mixing on the reproduction side is selectively permitted or prohibited. SOLUTION: An ATSI includes a first identifier to indicate whether the multichannel data in an audio packet is compressed or not and a second identifier to indicate whether the down-mixing of the multichannel data in stereoscopic two channels is permitted or prohibited.
