Advanced Audio Applications With SMPTE ST 2110-41

Work has been progressing in SMPTE and other standards bodies to define standards that will fully enable all features of Next Generation Audio codecs, such as Dolby AC-4 and MPEG-H, in ST 2110 networks. Standards are in place to support many current applications, but upcoming standards will enable new capabilities that can fully exploit all NGA capabilities, as well as future advanced audio applications. The SMPTE ST 2110-41 Fast Metadata standard currently is one key standard that will enable these functions. This session will cover recent work on ST 2110-41 and related standards for carrying rich audio metadata, including Serial ADM (ITU-R BS.2095) metadata. Recent work on file format standards that will enable seamless interchange of ST 2110 audio and metadata with file based workflows will also be discussed.
