scope:

This standard describes how data rate reduced (non PCM) audio streams conforming to ETSI TS 102 114 are packed into an AES3 data stream, following the methods described by SMPTE ST 337. The type of data in the AES3 stream is identified by a data_type value as defined by SMPTE ST 338 and carried in the burst information word of the data burst preamble. Since the data_type value associated with ETSI TS 102 114 is 17, the term 'Type 17' in this document will refer to a bitstream conforming to ETSI TS 102 114, comprising a "core substream" defined in Chapter 5, and / or "extension substream" as defined in Chapter 7.
