ETSI ETSI TS 102 114 V1.5.1 (2018-05)17 1 Scope The present document describes the key components of the DTS Coherent Acoustics technology which is known in the market as DTS-HD. Prior editions of the present docum
31、ent added Annexes describing stream encapsulations of the bitstreams defined herein for MPEG-2 Transport Stream (based on ISO/IEC 13818-1) and ISO Based Media Files (using ISO/IEC 14496-12 5). This edition has been extended with two new Annexes that describe particular methods of network distributio
32、n of the defined bitstreams using MPEG-DASH (ISO/IEC 23009-1 3) and MPEG-CMAF (ISO/IEC 23000-9). 2 References 2.1 Normative references References are either specific (identified by date of publication and/or edition number or version number) or non-specific.
