AUDIO ENCODING METHOD, AUDIO DECODING METHOD, AUDIO RECEIVING DEVICE, AND AUDIO SIGNAL TRANSMITTING METHOD

摘要

PROBLEM TO BE SOLVED: To enable a reproduction side to make reproduction normally even if multichannels are selectively transmitted by compression or non-compression and even if downmixing on the reproduction side is selectively permitted or prohibited. SOLUTION: 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 downmixing of the multichannel data in stereoscopic two channels is permitted or prohibited. Consequently, when data transmitted by packetizing the identifier to indicate whether the multichannel data are compressed or not and the identifier to indicate whether the downmixing of the multichannel data in stereophonic two channels is permitted or prohibited are received, the data can be decoded and reproduced normally.
