SMPTE ST 2101 – Format for Non-PCM Audio and Data in AES3 – AC-4 Data Type
This standard describes how AC-4 data rate reduced (non PCM) audio streams conforming to ETSI TS 103 190 are packed into an AES3 data stream, following the methods described by SMPTE ST 337. The AC-4 data type is identified by a data type number listed in SMPTE ST 338 and carried in the burst information word of the data burst preamble.
